Re: [slurm-users] X11 forwarding and VNC?

2019-04-09 Thread Marcus Wagner
Hi Loris, I know, it has been some time, but I have one additional remark. If you just use ssh -X to login to the nodes, you will have a plain ssh session, which means, none of SLURMs environment variables will be set. So if your X11-Jobs are in need of that, you will have to use X11 forwarding

[slurm-users] Effect of PriorityMaxAge on job throughput

2019-04-09 Thread David Baker
Hello, I've finally got the job throughput/turnaround to be reasonable in our cluster. Most of the time the job activity on the cluster sets the default QOS to 32 nodes (there are 464 nodes in the default queue). Jobs requesting nodes close to the QOS level (for example 22 nodes) are scheduled

Hi Marcus, This is a good point, thanks! Maybe the salloc variant isn't so good as a general solution. Cheers, Loris Marcus Wagner writes: > Hi Loris, > > I know, it has been some time, but I have one additional remark. > If you just use ssh -X to login to the nodes, you will have a plain ss

Re: [slurm-users] Effect of PriorityMaxAge on job throughput

2019-04-09 Thread Michael Gutteridge
It might be useful to include the various priority factors you've got configured. The fact that adjusting PriorityMaxAge had a dramatic effect suggests that the age factor is pretty high- might be worth looking at that value relative to the other factors. Have you looked at PriorityWeightJobSize?
