I had a power dip during a thunderstorm that crashed the system doing the LA. Which delayed it a few hours and lost the total time (it took about 128 hours in total).

The relations file for 165__521_7m1 seems to be truncated due to the Pentathlon craziness. There are only 33M relations so about half are missing in action. Any suggestions?

Is this relations count confirmed via download and running msieve? We can bump up Q to generate more rels of course but is the data displayed correct?

Give me 15 mins, will give you an answer. On filtering stage.

Sorry I had gone to bed after my post. Yes, I had downloaded and filtered the relations file with msieve. I think we will need more than 10M additional Q.

What target_density did you specify when starting msieve? Or did you just go with the default value (TD=90)?

There appears to be plenty of relations for a job this size but who knows with the recent tsunami resulting from the pentathlon.

165__521_7m1 is in LA. ETA tonight (or tomorrow morning if I fall asleep).

Thanks for adding another 50M to my number. I will let you know if I need more added to it

I have to agree the pentathlon has had noticeable effects i.e. stopping results for smaller numbers been sent out for a day or more. I hope it was successful for everybody involved.

Looks like you are missing part of the dataset file. At the time, the server was reporting about 65M rels but Msieve only read in 52M. If you re-download the new dataset it will have about 75M records. This will cause an over-sieve condition, which will need to be addressed in a different way.

I suspect a portion of the generated relations never got into the data file during hurricane Pentathlon but you might be right.

Jarod - just watch for a lot of relations (i.e. an oversieved condition) when you next attempt this job. If so, use the filter_maxrels= flag when invoking msieve.

[CODE]
msieve -v -nc “target_density=110 filter_maxrels=65000000” -t 4
[/CODE]

Or similar (if needed).

I just downloaded and got this job into LA. See attached log file. I have stopped the job now - it is yours to factor. But there are sufficient relations now.

Suggest you delete the current .dat file from your local machine and redownload it.

You may want to limit the number of rels handled in filtering (as discussed earlier in this thread) to avoid an oversieved condition.

The number of relations for the 30 bit job 692__361_7m1 looks incorrect. I could not find the poly in the 14e queue thread to check.

[QUOTE=richs;580283]The number of relations for the 30 bit job 692__361_7m1 looks incorrect. I could not find the poly in the 14e queue thread to check.[/QUOTE]

It’s a 29-bit job, sent to me privately. The job shows 30-bit but that’s just the default value I failed to correct when enqueuing it.

It should run just fine. Sorry about that. I’ll correct the bit field once it’s factored.

[QUOTE=RichD;584512]Pretty impressive. Do you know how big of a matrix can be solved on that 16G card?[/QUOTE]
It's the 32 GB version, but we need to store both the matrix and its transpose on the card in CSR format. Otherwise random reads from global memory kill performance. So we can go up to about 25M matrices, probably a little larger, on a single card.

Larger matrices can be divided across multiple GPU's with MPI. Currently, though, we have to transfer vectors off and back on the GPU for the MPI comms multiple times in each iteration, which introduces a large performance hit. I've added support for CUDA-aware MPI but OpenMPI still transfers off the card for collective reductions. MVAPICH2-GDR I think supports collective reductions on the card, but it's still being tested on the SDSC Expanse cluster. Hopefully that will be working in a few weeks. But for now quick tests show a 43M matrix on two cards in ~70 hours and an 84M matrix on four cards in ~350 hours.

275__471_7m1 is factored and posted. The 4.9M matrix took 37 minutes to solve on a V100.

It takes me longer than that to download the dataset of that size. :smile:
