[QUOTE=VBCurtis;534266]Welcome to the club, sir! I hope your new machine proves a rocket.[/QUOTE]We are actually running this on our gaming PC using the Linux subsystem in Windows 10. We recently upgraded the CPU from 4 real cores to 8 real cores so we can run msieve in the background on a few cores and not notice it.

A few days ago we downloaded the relations for an already-taken job and it is running as we speak. We are using this job as a verification run to make sure everything works.

[QUOTE=VBCurtis;534266]Welcome to the club, sir! I hope your new machine proves a rocket.

xyzzy joining us reminds me- we don't have a benchmark matrix-solve to compare hardware, do we? Like, it might be nice to have a dropbox/etc with a sample job available, say something that produces a matrix 5M or so in size. Folks who wanted to compare hardware speeds could D/L this job and note elapsed time to run it.

Is this something worth pursuing?[/QUOTE]

There’s a thread from Tom for a msieve benchmark dataset he hosts.

[QUOTE=Xyzzy;534277]A few days ago we downloaded the relations for an already-taken job and it is running as we speak. We are using this job as a verification run to make sure everything works.[/QUOTE]This run ran flawlessly under the Linux subsystem for Windows. For some reason we thought it would not work.

Eight real cores at 4.5GHz and 3200MHz DDR4 memory made for a fairly speedy run time. We paused the process several times to play games. We also started it with just two cores before we realized that we could pause the process.

Or we can put a smaller one up. Just link us to the files.
