Linear algebra reservations, progress and results - Page 185

If you are using Linux etc this script could be helpful.

Rename to waitfor.sh and run as follows:

Code:

waitfor.sh 12345;next_command -parameters

Replace 12345 with the PID of the job that's running now. When that stops waitfor.sh will soon end and the command after the ; will run.

Reserving C190_179743_47, once it's done sieving later this week. Hard to tell it's actual status - the estimated pending relations field seems a bit wonky - but I believe a matrix can be built.

In other news, the three big NFS jobs I currently have reserved should all finish this week.

Reserving C194_69655517_31

C217_143_51 will be a bit late (probably Thursday) because I forgot to check it was running before going home for the weekend.

fivemack · 2017-07-18, 16:24

C194_69655517_31 needs significantly more sieving (399189213 relations of which 313468110 unique produces a 25.9M matrix at density 70) so I've added another 25% to the range.

C190_179743_47 has managed to build a matrix at TD=70. 648 hrs ETA. I'll just grind it out.

No, no, no. Ask Tom to push more Qs for it. In the mean time you can take C216_143_53 since I won't be back home to start it until the weekend.

Chris2be8 posted a nice utility but I didn't have time to test it before my departure. I do see other uses for it and possibly post-processing in the future.

I get what you are saying but how much time will be saved with more Q and a tighter matrix (say TD=120)? A few days or is it a significant % saved?

You keep C216_143_53 - it's only a few more days to the weekend. I'm a bit overcommitted as it is. But I'll keep my reservation for C190_179743_47, however it plays out.

391896643 raw relations with 310335082 unique produces a 26M matrix @TD=70. I've paused this job for now.

From memory I've been running about 380-400 hours on 32-bit jobs with TD=120-130 on a Core-i5 2500K with four threads.
