We are done with 11.2, and we moved the guns on 11.0 right now, where there are still about 18 factors to go.

We know our intention in June when we started was to get all 11M done, but right now we see that 11.7 is momentarily busy, so we will stop after we are done with 11.0 (we did other ranges meantime too, so we are even ).
Meantime we will do some remodeling inside of the boxes we own...


Happy, fruitful, and healthy new year to everybody!

============= So you can do even more ranges?????

I started tickling 6.1M, as it seems there is nobody working there (from the first post in this thread) - if otherwise, please say and I will relocate myself. This is (slow? no idea!) CPU work, and the main reason is to see what the so-much talked about, newer versions of P95 can do (I am far behind with the news there, still using old versions and Win7). For now I am using B1=6M1 and B2=TBD, 6 workers, each in 3 cores in a 18-core machine, about 5 hours per test per core, so in average less than one hour per test.

Let's see how it goes...


Edit: @Wayne, thanks, and stay safe wherever you are walking your bones right now, I have seen you took all the ranges...

As they say: "Get in the game".
You really really REALLY need to upgrade to 30.8.
Then you need to run 1 Worker / 18 Cores and give it all the RAM you can afford.

My 7820X with 24 GB allocated to P-1 under 30.8 is about 20X faster than it was in version 29.x.
Briefly with the excessive RAM it will choose B2 about 300X B1 (rather than 30X) so you'll probably want a lower B1.

Have fun...we are Mexico bound this time.

I actually tried 1x18, 2x9, 3x6, 9x2 and 18x1, and it seems that the one with the highest output is 6x3. The toy has 64GB and 48 of them are allocated to P-1 stage 2, with MaxHighMemWorkers set to 3, so in any moment I have 3 workers doing stage 1 and 3 workers doing stage 2 with about 16G each (albeit I have seen as much as 28G for a worker). The combination you point at, will use a lot of memory in stage 2, therefore a high B2 and it is very good when hunting for very large factors, but my goal here is to get just "enough" factors, I would be happy if all of them are 73 bits , and the output seems a bit faster.

However, there is a lot of place to experiment here. Yeah, I installed 30.8 build 7, and the 18-cores toy is a win10 machine. I also experienced some... could not call them crashes, hehe, P95 just PUFF! disappears and its memory is released properly. I don't know what causes it. I run it again, and it is ok (no restart of the computer). Need more investigations too.

Here is the strategy I use. I run B1-only using the most efficient setup (which in my case is 1 worker per core). Then I do a second run for the stage 2 (on a different folder) with 1 worker x all cores.

With 30.8, you do NOT want more than one worker entering stage 2.

Set B1 to much smaller, say 2m or 1.5m.
Use 30.8 for stage 2 with 1 worker x 18 t, 48-56GB allocated. Watch the exponents just fly.

Yeah... Anyone still running <v30b5 for any P-1 work should DEFINITELY upgrade! It's absolutely amazing; stupidly high B2 for effectively free!

BTW... A bit of a tangent, but some might find this interesting to experiment with...

I'm doing some evaluations of the different Cloud Providers for a client. The three AWS outages last month are causing many to realize that perhaps true provider redundancy might be worthwhile for business continuity...

Anyway... This is not an endorsement, but I'm finding Oracle Cloud to be quite good. They offer a $300 / one month "Free Tier" to play with.

The compute is actually quite competitive compared to the other cloud providers. And it was fun pumping out factors with two six-core, 128 GB machines for a few weeks... I still have a couple of smaller VMs that I'm paying for, just to clean up a bit...

Is someone active in 7M? The reservation post on page 1 does not show anything.

Empirically, /someone/ has done a little bit of P-1'ing work in 7.0 and 7.1M over the last few days. No factors found yet.

Would you like to stake a claim? 7.3, 7.7, and/or 7.8M are yours for the asking.

Thanks, Chris!
Until 29.8M is nearly done, I will not reserve anything new just now, but I cast an eye on 7M and wanted to make sure it is free beforehand.

I will reserve it once I am ready at last. Until this, it is of course free to grab for everyone else!
