[QUOTE=pinhodecarlos;340469]Can you elaborate more? NVIDIA or AMD cards?

CUDA with CUDA-aware MPI. Beyond that, it is still on the drawing board, so no details to give yet. :smile:

It's going to be an expensive LA hobbie. Combining 2, 3, 4 and 6 GB Nvidia cards to run a linear algebra...11_10_233m can only be run at least on 3+4 GB Nvidia cards or in two 4GB Nvidia cards. Here it is using 7.4 GB of memory.

The big clusters are increasingly relying on using heavy-duty GPUs to get major performance numbers, so we need to ride that wave.

It's not going to be easy, plus my time has been unusually tight.

Hint: The whole matrix may not need to fit on the card at the same time.

@pinhodecarlos
11_10_233m is less sieved than the others however to make the matrix 100 hours faster to solve would need many 100s of hours more sieving. It has been noted that the larger numbers that were solving quicker had more than efficient oversieving.

Great conclusion you reached. Thank you very much.
Have you been reading all the discussion? I don't think so otherwise you wouldn't post such comment. You need to stop posting on threads you are not at all related. It's usual from your side, you think you know everything...stop that...it's annoying.

Who's running L1752? If it's available I'd like to take it, since L1809 won't be ready for a little while

(though it is perhaps silly for me to use my giant stomping machine on something which has been that thoroughly oversieved; if anyone else jumps in I'm willing to hand it over)

L1752 is free and unreserved. You can start it.

Started

Due to BOINC Pentathlon I will be delaying 11_10_233m post-processing by 2-3 days. I'll be helping team SETI.USA on Asteroids@Home project. I made this call because SETI.USA always answered to my calls to help here at NFS@Home sieving. Anyone cares to join me?
