gpuOwL-specific reference material
This thread is intended to hold only reference material specifically for GpuOwL.
(Suggestions are welcome. Discussion posts in this thread are not encouraged. Please use the reference material discussion thread http://www.mersenneforum.org/showthread.php?t=23383.) To get started in gpuowl, on linux, see Ernst Mayer's directions: https://mersenneforum.org/showthread.php?t=25601 For Windows, see below. In either case, note that the computation types, hardware supported, fft size limits, file formats, etc have varied greatly and rapidly over the course of the hundreds of versions. Choose version according to what you want to run and what each offers. On a completed install of Windows (may as well have done Windows updates to current also): Enable or install and configure any remote desktop software you plan to use; Windows Remote Desktop, TightVNC, etc. Create a working folder. (I create one for each instance for each gpu.) Do create it as a subdirectory of the user's default folder. Permissions will be ok there. DO NOT place it in system directories, Program Files, etc. Permission problems are common if attempting to run there. Get and install the gpuowl software Either download a current build from the end of the Gpuowl Windows build thread https://www.mersenneforum.org/showthread.php?t=25624 or for an earlier version https://www.mersenneforum.org/showpo...39&postcount=4, or from the download mirror https://download.mersenne.ca/ which has many Windows versions and a few Linux versions. Unzip it into a working folder under the user's home directory (NOT in Program Files or other restricted areas as some have attempted, and run into permissions problems). Or follow the Windows build instructions at https://www.mersenneforum.org/showpo...4&postcount=21 to create a build environment (once) and follow the compile and link section there as needed. Next, decide whether you will run it manually or use primenet.py. If using gpuowl's primenet.py or certain other tools provided for gpuowl, you'll need a Python 3 installation. For Python, follow the instructions of a good one, such as https://docs.python.org/3/using/wind...l#windows-full (I've been exploring compiling primenet.py into a standalone executable, but haven't quite worked out how to get one small enough to post it on the forum as an attachment yet.) I recommend running one instance of gpuowl manually at first, to learn what normal operation looks like, so that if/when issues with operation appear, you're familiar with the program. (Add complexity later, after learning the basics.) It will also give you a greater appreciation for the automation built into primenet.py and other programs such as prime95 and mprime. Note, not all gpuowl versions include all the features described below. Some are rather recent additions. Create a config.txt Suggested contents: -user your-primenet-uid -cpu systemname-gpumodel-number-winstance -device n -maxAlloc gpuram-delta For example, since my primenet-uid is kriesel, for system asr2, second Radeon VII gpu, instance 2, the gpuram is 16GB total but if I have 2 instances running P-1 on the same gpu and their stage 2s might coincide, I might use maxAlloc= gpuram 8000 - delta 500 =7500 for each instance. Then the config.txt line for the second gpu, second instance would be -user kriesel -cpu asr2-radeonvii-2-w2 -device 1 -maxAlloc 7500 (Device numbers start at 0 in gpuowl and some other GIMPS gpu applications.) Other -options are given in help output. -yield or -power 8 may be useful. I find it useful to create a short batch file also, and desktop shortcut to it. The batch file can be as simple as g6.bat: Code:
title %cd% gpuowl-win The shortcut command should not be a direct invocation of the batch file. Use a cmd /k prefix so the window lingers in case of problems, to give you long enough to see and read any error message. Having the help.txt and use-flags.txt files in the working directory for ready reference is also convenient. Create a worktodo.txt Go to https://www.mersenne.org/manual_assignment/ to get a single PRP assignment or PRP DC assignment. The excellent Gerbicz error check GEC) on PRP work will determine whether the gpu is producing reliable interim results. Verify the gpu and system combination is reliable in PRP/GEC, before attempting any P-1 factoring or LL DC, which have less error detection. Open worktodo.txt for editing. Paste the assignment into worktodo.txt and follow it with a return. Save the modified file. Try running gpuowl via the batch file at a Windows command prompt: g6 If it works, it should look something like the following, allowing for differences in parameters entered in config.txt, gpuowl version, exponent, work type, etc. If not, fix and retry. A PRP start: lines should contain "OK", "EE" instead means errors, trouble, perhaps clocks set too high or unreliable system ram or a failed fan. Code:

Verify you're logged in (see upper right of the web page.) Open the results.txt file in an editor. Copy the result. Paste it into the results field of the web page. Click on "Submit". Optionally, enter a note that the results line has been reported. I usually use "reported mm/dd/yy" filling in the date. Upload the proof file (AFTER reporting the result record) There's only a proof file for PRP runs begun with proof-capable versions of gpuowl. It's found in subfolder proof, and has a name composed of the exponent and proof power. For example, exponent 1234567 power 8 would be 1234567-8.proof in folder workingdirectory\proof. There are several possible upload methods listed at https://www.mersenneforum.org/showpo...0&postcount=26 for which some have the steps described there. Using multiple instances There are two ways that running multiple instances on the same gpu at the same time may increase throughput. 1. Aggregate throughput may be higher running two instances on the same gpu at the same time. Any wait time that occurs for one instance on the gpu while the cpu performs the GEC, or reads from or writes to files or the console, or moves data over the PCIe bus between gpu ram and system ram, may be usable by the other instance. 2. Emptying the worktodo file or halting on an error condition by one instance does not completely stop progress; any other running instance then can use resources the stopped instance is no longer using. A single instance if halted does not leave the gpu idle for hours or days if at least one other instance is still running on it. Multiple instances are not guaranteed to improve sustained throughput. Throughput seems to be better if the two instances are running similar code an parameters; two 5M fft PRPs for example (not a 5M and an 8M, or P-1 and LLDC). The conceptually simplest way to run multiple instances is to create a separate working folder with its own set of files including gpuowl executable, same as the first instance. A more compact way is to use the executable in a common folder by all instances of all gpus, IF updating version on all instances simultaneously is ok. Backups Now might be a good time to refresh your Windows backup, system restore point, etc. Also verify that your gpuowl folders, containing assignments, results, interim save files, configuration, etc. will be backed up. Using gpuowl's primenet.py There's a separate post detailing primenet.py setup and use at https://www.mersenneforum.org/showpo...2&postcount=25. It's probably best to rename the results file containing already-reported results before starting to use primenet.py for reporting. Pool I haven't tried it yet, but particularly with multiple instances, multiple gpus of the same type, or both, it appears it could make manual work assignment and result reporting easier. The help output says: Code:
-pool <dir> : specify a directory with the shared (pooled) worktodo.txt and results.txt Multiple GpuOwl instances, each in its own directory, can share a pool of assignments Table of contents

GpuOwL run time vs exponent or fft length or version
RX550 data
gpuOwl v2 5000k fft RX550 gpu, MSI 18.2.3 driver Feb 26 2018:in a quick test (~40,000 iterations each) was: short carry 17.3 ms/iter, medium 17.6, long 17.4, compared to V1.9 gpuOwL on the same gpu, same pcie physical connection, April 2017 MSI driver, 10.9 ms/iter for -fft DP -legacy -size 4M; 18.9 ms/iter -fft M61 -size 4M; 21.4 ms/iter -fft DP -legacy -size 8M. The driver change coincided with an increase by about 5% of iteration time, on the same gpu, in V1.9 gpuOwL. http://www.mersenneforum.org/showpos...&postcount=370 See the first attachment below for V1.9 on an RX550. See also the 4-program speed comparison in the general reference thread. http://www.mersenneforum.org/showpos...76&postcount=8 For an RX480 my data indicates 3.4-3.6 times faster than RX550, on the same exponents and gpuOwL versions, at http://www.mersenneforum.org/showpos...&postcount=386 and subsequently An Intel IGP HD620 could run V0.5 or v1.9 but it was not worth doing. On mine the hit on prime95 throughput was larger than the gpuOwL throughput as a result. More detail on the V0.5 try (LL): http://www.mersenneforum.org/showpos...&postcount=176 (I discontinued running gpuOwl on the IGP. The tradeoff with mfakto there was much better.) Detail on the V1.9 try (PRP): http://www.mersenneforum.org/showpos...&postcount=285 A listing of V3.5 OpenOwL command line options and fft lengths can be found at http://www.mersenneforum.org/showpos...&postcount=565 Detail on benchmarking V3.3 and V3.5 OpenOwL fft lengths on RX480 can be found at http://www.mersenneforum.org/showpos...&postcount=570 Second attachment below tabulates ms/iteration timings for various versions, V3.x - V3.9, V4.6, and V5.0, and fft lengths, on an RX480, and includes some graphs and ratios. Third attachment compares V6.2, 5.0, 3.8, 2.0, and 1.9. Each are fastest for some fft length / exponent ranges, except v2.0. The trend line fit for asymptotic scaling of the fastest version versus fft length or exponent is iteration time p^{1.078}, so run time p^{2.078}, for exponents 100M<p<~2520M (6M to 144M fft length).

gpuOwL bug and wish list
Here is the latest posted version of the list I am maintaining for gpuOwL. As always, this is in appreciation of the authors' past contributions. Users may want to browse this for workarounds included in some of the descriptions, or for an awareness of some known pitfalls. Please respond with any comments, additions or suggestions you may have, preferably by PM to kriesel.

Getting started with gpuOwL
This is an old post, but kept in place for its documentation of what can be done with the very old builds, and the long list of (mostly Windows, plus rarely Linux) builds available.
See the Available Software guide portion for gpuOwL, for where to get code, a brief summary of capability, and a discussion thread for it. Or scroll to the bottom of this post. Note this was originally written for very early versions, and that has been left in place here for those occasions when an old version is the best tool for a particular task. It's pretty simple to get started with gpuOwL. Get the version that supports the fft length corresponding to the exponents you want to run, and build it for your operating system, or find a suitable executable someone else has already built. Kracker was kind enough to post build directions for Windows (including setting up a free open source build environment) at http://www.mersenneforum.org/showpos...&postcount=356 and a Windows build or two in the past in that same thread. Install the OpenCL drivers on your system and confirm function with a separate OpenCL query utility. Make sure you have gpuowl.cl in the working directory. For V1.9, depending on the transform type used, you may want nttshared.h in there too, such as if using -fft M61. (See http://www.mersenneforum.org/showpos...&postcount=224) No ini file. Very little setup. Manually check out some exponents for PRP test or PRP double check (unless you're using an old version that does LL, get that type of assignment instead) and put those records in a file called worktodo.txt, just as mersenne.org's manual checkout gives them. You may want to use a small shell script or batch file depending on which OS you're using. Syntax and options change with gpuowl version. https://www.mersenneforum.org/showpo...&postcount=353 V0.6 syntax example: Code:
gpuowl -logstep 5000 -savestep 2000000 -checkstep 250000 -uid kriesel/condorella-rx550 Code:
:set opts=-fft M61 -size 4M set opts=-legacy set dev=2 gpuowl -user kriesel -cpu condorella-rx550 -device %dev% -verbosity 2 %opts% For V2 it's also simple, and somewhat differs: Code:
gpuowl -device 0 -user kriesel -cpu condorella-rx480 -carry long http://www.mersenneforum.org/showpos...&postcount=370 In V2 there's a -step option; see http://www.mersenneforum.org/showpos...&postcount=353 V3.x is different yet. See for example http://www.mersenneforum.org/showpos...&postcount=565 As is V4.x. As is V5. Code (for Windows unless otherwise indicated) For gpuOwL Windows code, and source see http://www.mersenneforum.org/showthread.php?t=22204 An early guide for compiling 0.x on windows with msys64+mingw64 http://www.mersenneforum.org/showpos...3&postcount=26 Windows in current versions includes the ability to handle .zip files but does not include support for some other compressed archive forms.

gpuOwL requirements
My current understanding of the requirements, from the Windows point of view
OpenCL installed, at least version 1.2 if not 2.0. (Some of the more recent versions require OpenCL 2.0) One or more units of OpenCL compatible hardware, with corresponding driver(s) supporting OpenCL of the required level, such as certain AMD GPUs, Intel IGPs, or CPUs. NVIDIA gpus with compute capability somewhere above 3.0 began to be supported at gpuowl v6.5. Currently GTX10xx and newer NVIDIA model gpus work, and somewhat older too. gpuOwL below v6.5 does not currently run on NVIDIA gpus, on Linux or Windows, and to my knowledge Preda's releases before that did not. http://www.mersenneforum.org/showpos...&postcount=277 Someone reported porting a long ago version for his own use. http://www.mersenneforum.org/showpos...&postcount=107 Per instance, gpuOwL v1.9 on 8M fft length running exponents ~150M, exhibited in Task Manager, ~115MB private working set, 145MB working set, 382MB peak working set on Windows 7 64-bit. Meanwhile GPU occupancy was ~475-490MB each. Discrete (add-in card) GPUs give better performance because of their dedicated memory. Integrated graphics processors use memory and TDP budget shared with the CPU core(s) and will affect performance of CPU applications. IGPs may lack DP support or otherwise lack compatibility with the AMD-oriented gpuOwL DP code, and so require running V1.9 -fft M61, which is slower. In case of difficulty, it's recommended to verify the successful installation of OpenCL and compatible drivers with a utility, such as clinfo, oclDeviceQuery.exe, or the advanced tab of GPU-Z (a Windows gpu status graphical utility). Memory requirements are modest. I'm seeing only about 290MB occupied during 4M fft length -DP transform on an RX550. That may scale to roughly 1.3GB for a future 16M fft implementation, 2.7GB? for 32M, which would not fit on that 2GB card. (It would probably also run way too slowly for that card to be practical, at roughly estimated 2-3 years per exponent.) It illustrates that for primality testing, 4GB is probably enough for a long time. gpuOwL v2 on Windows 7 sp1 with current updates failed with an MSI-sourced driver dated April 2017 on an MSI RX550. It worked with the MSI driver 18.2.3 dated Feb 26 2018. There's a March 23 2018 driver available from AMD, v18.3.4, or probably more recent by now, that I have not tried on v2.0. https://support.amd.com/en-us/download Top of reference tree: https://www.mersenneforum.org/showpo...22&postcount=1 Last fiddled with by kriesel on 2020-08-09 at 19:17 Reason: update for v6.5 |

gpuOwL features and requests
(caution, some of this is outdated. gpuowl is up to v6.5 as of 2019-05-09.)
Nice features The Gerbicz check, of course, detecting errors and allowing timely rollback to ensure an accurate result. Full time logging in addition to console display. The -step argument in gpuOwl It seems to me after a quick look at the source, the ability for the user to override the automatic program behavior, with a specified constant step count between Gerbicz checks. I interpret this to mean -step requires a step count parameter in the range 1000 to 500000 that are 1, 2, or 5 times a power of ten; 1000 or 2000 or 5000 or 10000 ... 500000. Or perhaps larger also. It may be both output and Gerbicz check interval. Two use cases I've run into are: 1) Hardware and software are very stable, exponent is far from an fft length limit, overhead of starting at small step sizes is not necessary, run a large step size from the start. (This case might benefit from adaptive step size after starting large if an error occurs during the run. Also user settable number of consecutive retries if an error occurs) 2) Repeatable error has occurred, such as the exponent is slightly too large for the fft length, I'd like to determine as finely as possible, at what iteration it occurs, with a rerun from last known good save file, using minimum step size until encountering the error again. (This case might benefit from a user set limit of retries (0 - ~9) before giving up on the exponent and starting or resuming the next worktodo entry.) Source fragments supporting the opinion are at http://www.mersenneforum.org/showpos...&postcount=353 The ability to switch transform midstream Per Preda the author of gpuOwL, the save file is in compacted bits format (independent of the transform). see http://www.mersenneforum.org/showpos...&postcount=312 Feature requests Save frequency option Is there a command line option to control the frequency of saving a disaster-mitigator interim file, which seems to be produced at 10^7 iterations intervals in V1.9? I would like to try running at 5M iteration intervals for safety files. I don't see any in the V1.10 source. I suppose I could run some little batch file. Gpu operation priority lower for gpuOwL computation or periodic yielding by gpuOwL When running gpuOwL on the same card running the display, and using the local display rather than remote access, the screen seemed sluggish; I'm not aware of any option in gpuOwL equivalent to the -polite option in CUDALucas, which gives display operations a turn now and then (with frequency user settable). A port to NVIDIA! More fft lengths where useful, integrated into one application; 4M and 8M DP and M61 fft; 5000K DP, and anything new.

Determining upper exponent limit for a transform type and fft length
In gpuOwL V1.9, a lengthy experiment was conducted on how to efficiently determine the upper exponent limit for PRP with Gerbicz check for a given fft length and transform type. This was conducted on the M61 transform type and 4M fft length, for which the program author did not know the limit. (It was not possible to do it on 8M fft length, since maximum exponent is higher for the M61 transform than the corresponding DP transform, and the program's maximum exponent was capped at the 8M length DP transform approximate limit. It would also have taken more than 4 times as long.) The calculations were performed on a relatively slow RX550, which contributed significantly to the experiment's calendar duration.
By approaching the limit from above, generating error failures quickly in relatively few iterations, convergence to an approximate limit is achieved much faster than approaching the limit from below, with fully run to completion exponents. This might seem like a lot of iterations would be wasted for runs that generate errrors. However, gpuOwL in v1.9 and later had the useful property of storing interim results in a form that could be continued by a different program version and transform type. So a run that produces errors at a few million or even tens of millions of iterations with one transform type and fft length can be continued to completion by a different program version, transform type, and fft length. Many of the exponents that generated errors as M61 4M, have been run to completion with newer faster DP fft lengths as PRP tests or PRP DC tests on an RX480, as will be a few more still remaining. Tabulating exponents tried, the success or failure, number of iterations completed, and fits through the failure data and success data separately, produce a good picture of a limit estimate. In this way, it can be determined to fairly close accuracy where the limit of completion lies, while doing work useful to the GIMPS project progression in first-time or double check effort. Tabulating along the way, with spreadsheet-generated regression fits, was used to somewhat guide the selection of next trial exponent. When practical, avoiding overlap with existing assignments was also considered in trial exponent selection. In the example attachment, about 1.06 exponents' equivalent of failed run iterations, plus 5 completed exponents, were used, to determine a limit value around 83869400, within a span of about 190 out of ~84 million, or 2.24ppm. Approaching strictly from above, stopping when two exponents are completed, and using less closely spaced test exponents, one could reduce the work to less than the equivalent of 3 completed exponent runs. At a cost of at most one full run per trial, the experiment could be extended to give about one bit more precision in the limit per additional trial. The practical utility of adding more bits precision to the limit is low, since there are only 5 currently unfactored candidates between 83869319 and 83869507, all of which have a LL or PRP result reported currently, and there are considerably faster fft length/transform combinations available now for performing primality or pseudoprimality tests in that exponent range. https://www.mersenne.org/report_exponent/?exp_lo=83869319&exp_hi=83869507&full=1 It's worthwhile to note that the limit value determined is not a guarantee that an exponent below that value would be certain to run to completion without error. It's merely a limit below which no error was seen, in the hundreds of millions of iterations required for the 4 exponents that completed. The error occurrences are not predictable, within a span of exponent of 15,000, and seem to behave statistically. The limit of the M61 4M transform appears to occur at about 19.996 bits/word, or approximately 20 - 1/256, somewhere between 83,869,319 and 83869507.

gpuowl V6.11, 6.7, 6.5, 6.2, 6.0, V5.0-9c13870 fft lengths, and earlier
Prior to theV5.0-9c13870 commit, the M=3 in the V5.0 list were not available.
Prior to V5.0-df2bdf2, <0.5M were not available. Prior to ~V3.5, the M=5 and M=9 were not available. V3.3 supported 4, 5, 8, 10, 16, 20M. V2.0 supported 5M only. V1.9 supported 2, 4, and 8M. V1.0 and earlier were 4M only. (I think the earliest PRP was at V0.7, prior to that it was LL) V5.0: Code:

PRP3 run time scaling in V5.0-9c13870 (no P-1)
Gpuowl PRP3 has been run on all known Mersenne prime exponents feasible on its currently available fft lengths, mostly in ascending order. This provides run time scaling, reliability check on the hardware, and a check for any occurrence of false negatives or error detections, from the same run set. The test is being run on an RX480 under Windows 7 x64, along with a running instance of prime95 and mfakto running on an RX550 in the same system.
For the exponents below 216091, the minimum available fft length, 128K, is too large, giving bits/word below 1.5, and in most cases immediate fatal errors. p=132049 runs briefly, at 1.01 bits/word, but detects Gerbicz check errors repeatably in the initial 800 iteration block and exits after 3 rounds of that. For exponents 216091 to 1398269, the run time is highly linear since they all are run at fft length 128K; p^{0.99}. For exponents above 1398269, since the fft length is chosen approximately proportional to the exponent, it seems reasonable to expect the scaling to approximate a power law above 2, since fft multiplication time is, per Knuth and other sources, proportional to n ln n ln ln n. Then a full PRP3 test would take n-1 iterations, or approximately n^{2} ln n ln ln n for large n. In the attachment for CUDALucas run time scaling at https://www.mersenneforum.org/showpo...23&postcount=2 there is scaling to p^{1.85} for 10^{6}<p<10^{7}, and to p^{2.095} for 10^{7}<p<10^{8}. Run time scaling for prime95 for 86243<=p<=2976221 was p^{2.094}.https://www.mersenneforum.org/showpo...78&postcount=2 The scaling for gpuowl appears to be lower than expected and lower than seen for other applications. For 1398269<p<10^{7}, runtime scales as p^{1.518}; for 10^{7}<p<10^{8} it is p^{1.72 to 1.88}, which implies an fft multiplication time scaling proportional to lower than linear, similar to a lower exponent range in CUDALucas. Perhaps gpuowl does not reach asymptotic scaling until higher exponents. From 100M exponent to 100Mdigit, the gpuowl scaling was p^{2.04}, consistent with that. Low n runs appear to be affected by setup overhead in CUDALucas and clLucas also, reducing the power seen in scaling fits. For gpuOwL, the OpenCl compilation each time contributes 2 to 3 seconds overhead. Frequent console or log output may also be contributing. Finally, and importantly, no false negatives and no detected errors were observed.
