Interesting! Can you send me the worktodo.txt, prime.txt, local.txt and savefiles?

I had previously done work on M36001457 with these settings: B1=800000, B2=16000000, E=12. The files of the work I do I keep in storage. I now added to worktodo a new assignment on this exponent with the same B1 value to see what B2 value it would choose and how much time it would use. (So to see how much time would be saved from using the previous done B2 value.)

To my surprise no line ended up in the screen about choosing a B2 value which turned out to be 80000000, exactly 100*B1.

I then added a line to worktodo on doing P-1 on M36024379 on which no previous work had been done on my machine. To my surprise it chose a very different B2 value.

I just wonder what causes this behaviour and if that is intended,

Next I will try to do work on a similar exponent with work done before and force E=12 to match up with the previous work done

Found a memory corruption problem when limited stage 2 memory resulted in selecting N^2 pooling instead of 3-mult pooling. Will be fixed in build 7.

Build 7 now available, see first post in this thread for links. The only fix is the memory corruption bug. If you've experienced crashes with earlier builds, please upgrade so that we can see if this fix addresses the crashes you were experiencing.

Hmm, no idea what to do with this. No idea about the stability of this machine either.

Getting even weirder: After having interrupted mprime (^C) and restarting mprime, it continued from a a backup file I did not expect to be used as first choice. I am lettting this machine run to see if the error is reproducible.

By the way, why does the menu get rewritten to screen after option 4 is chosen?

[QUOTE]
Getting even weirder: After having interrupted mprime (^C) and restarting mprime, it continued from a a backup file I did not expect to be used as first choice. I am lettting this machine run to see if the error is reproducible.
[/QUOTE]

Second run had no errors reporting

error -1 is bad FFT data, which raises a few questions. Why is this only detected during write save file process? Should getting this error during a write save file continue on with P-1 or should it restart from last save file?

Build 8 is now ready.

No bug fixes. There are 2 new modular inverse pooling algorithms. Previously there were two algorithms for pooling N values:
1) 3*N multiplies, N extra temporaries
2) N^2 multiplies, 1 extra temporary
The two new methods:
3) 3.44*N multiplies, N/3 extra temporaries
4) 3.57*N multiplies, N/7 extra temporaries

This gives prime95 more options in picking an ECM stage 2 plan especially in low memory situations. Expect a small speed increase in some situations.

I got a crash with build 7 doing ECM work on Linux:

But maybe that is intentional, I don't known if one can calculate the probability for a second factor...

AFAIK, the known factors should be formatted as ,"xxx":

[CODE]Pminus1=N/A,1,2,3333313,-1,500000,0,68,"220665927262967"[/CODE]

This should work properly.
