mprime was set to use 2,5 GB of ram which is more than sufficient to run this exponent with this B1/B2 setting. Can someone try this on his/ her machine? Could it be that the known factors are used as settings that don't make sense? Or that the line in worktodo should be constructed differently?

That's what you get for using a text editor instead of those fancy new fangled "user interfaces" :razz:

Your worktodo line looks fine. I didn't let it run to stage2 to see how much RAM it actually used. My [url=http://www.mersenne.ca/prob.php?exponent=22351237&b1=400000&b2=9000000]P-1 probably calculator said[/url] it [i]needs[/i] 186MB, [i]would like[/i] 555MB, and wouldn't use more than 4536MB even if it was available.

Running your worktodo as-is seemed to start fine:[code]Setting affinity to run worker on logical CPUs 2 (zero-based)

Do you have different day and nighttime settings? Do you have a memory setting for that particular worker?

I had copied the file
[CODE]mM351237[/CODE]
to the new directory. That file contained the data from the previous run on that exponent with the B1=400000 and B2=8000000 setting and done with
[CODE]Linux,Prime95,v28.9,build 2[/CODE]

I renamed that file now so it will not be used in a new run. It started stage 1 correctly an I will watch it over the next hours.

tha 2018-03-22 12:08

Same result. It first found the existing factors in stage1. I then restarted the assignment with Stage1GCD=0 added to prime.txt file. It still comes back with [CODE]Insufficient memory to ever run stage 2.
Stage 2 GCD complete. Time: 40.764 sec.
[Work thread Mar 22 12:39] P-1 found a factor in stage #2, B1=400000, B2=400000.
[Work thread Mar 22 12:39] M22351237 has a factor: 288476702225081262023002950746197048091558084285203081 (P-1, B1=400000, B2=400000)
[/CODE]

These last setting B1=B2=400000 it generates itself every time.

So I now renamed the file mM351237 again and restarted the assignment with the Stage1GCD=0 setting before embarking on stage 1.

I have daytime and nighttime both set to 2560MB.

If setting a memory for a worker involves some kind of tweaking through the menu or in prime.txt than I would have remembered since this download and install took place yesterday.

Also does not result in a start of stage2. Removing the known factors is the only way to start stage2, even with B2=12000000. However, we wanted to start the line with the known factors in place, to test if the server will accept the higher B1/B2 bounds for inclusion in the data available on the exponent.

Yep, that works!

Now wait and see what the server will store once the client makes the report.

I ran it on one of my machines, with 12GB of RAM available, with the requested parameters.

Found a factor after stage 1. Interestingly, these results we're reported by Primenet. I suspect this is because they are already known.

The test completed without any new factors found. As far as I can see the new B1/B2 limits were not accepted by the server, either because the exponent was not reserved or for any other reason. What would be desired is the server accepting the new B1/B2 limits.
