Prime95 beta version 28.3
 
Prime95 version 28.3 is available. This version is for you intrepid beta testers. I've run the torture test and done some QA, but I haven't run any double-checks yet. I don't expect any problems, and I am now using it on my computers.

This version includes nearly all the Haswell optimizations I plan on implementing. A few of these changes may also benefit Sandy/Ivy Bridge machines. On my Sandy Bridge I'm seeing a 1.5% improvement.

Placeholder for reporting bugs fixed

Anything specific you'd like us to do? I'll just queue up two or three DC's for each worker otherwise.

I have three IB's and a SB laptop I'll be testing :smile:. Are there any improvements from 28.2(1) for Haswell?

[QUOTE=kracker;364480] Are there any improvements from 28.2(1) for Haswell?[/QUOTE]
My Haswell went from 4.059 ms/iteration to 4.019 ms/it, so yes :smile:
(4 threads, 1 exponent)
Edit: Although the range of variation in time per iteration appears to have increased.

I don't suppose this needs testing from Ivy Bridge stress testing only users?

bayanne 2014-01-13 14:46

I'll test this on my Mac Pro ...

is it too late for requests?
 
Instead of one setting for # of iterations between screen updates...could it be either:
- # of minutes or hours between updates
Or
- allow a diff # of iterations for eack worker.

I find with mixed work types the time to complete X iterations is VERY different.
I have 1 core doing ECM on 2377 and another doing DC.
If I set iterations to 100000 for example DC updates about hourly and ECM every second. At 500000000 ECM every 10 minutes....DC never until it completes.

Thx

Linux link seems to be broken...

[QUOTE=blip;364541]Linux link seems to be broken...[/QUOTE]

Indeed.

Try [url]ftp://mersenne.org/gimps/p95v283.liux64.tar.gz[/url] instead (what's an "n" between friends)....

George.

I don't know under what environment you complied the Linux version in, but under CentOS 6.4 I get the following:

[CODE][chalsall@backup t]$ ./mprime -v
./mprime: /lib64/libc.so.6: version `GLIBC_2.15' not found (required by ./mprime)
./mprime: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by ./mprime)[/CODE]

Any chance we could get a "statically linked" version?
