comment Should I disable hyperthreading?
What do you mean by that? I was under the impression that slurm shouldn't impact performance if set up properly. Right now my stuff is taking way too long so performance is key. I'm trying to run a model (government written Fortran model) whose setup scripts require a workqueue manager, and slurm is the one our cluster came with.... Would a different queue make a big difference?

comment Should I disable hyperthreading?
I read that, but I was still having trouble making it target two nodes if it felt that one node wasn't full. Maybe htop isn't the best tool to measure how it's running. Reading this, and the previous answer, I think that I really just need to keep experimenting with different combinations. I'm getting the impression that hyper-threading is helping me out though, but still am not sure.

comment Should I disable hyperthreading?
ACK, I'm dumb. I was running lscpu on the headnode, and not on the Intel node. I edited the question to reflect this. (shouldn't have wrote this question at 1 am :( )

comment DNS points to the right IP, but I can't connect using DNS
I'm not sure it's working, but I'm also not sure I'm restarting my networking properly. ''service networking'' can't seem to restart it properly. I'll keep at it. Thanks!

comment DNS points to the right IP, but I can't connect using DNS
I thought so to, and should have mentioned it above, but my system firewall, ufw, is disabled/inactive. But, turns out that this is now strictly a local problem, unfortunately I had entries in my ''/etc/hosts'' on the remote systems I was testing pointing at a bad IP.

comment DNS points to the right IP, but I can't connect using DNS
It actually reads ''hosts: files mdns4_minimal [NOTFOUND=return] dns'', I'm not familiar with this file though and will have to read up on it. Could this explain why it fails locally? Thanks!

comment DNS points to the right IP, but I can't connect using DNS
That's a fair point. Thanks for your help! So, locally it still doesn't work, but it does remotely. Turns out the system I was testing it remotely from had an entry in ''/etc/hosts'' to an old IP, I completely forgot about this, and didn't check since the local failure seemed so similar.

comment Simultanious process mysteriously ending
Thanks @shavenwarthog. I've added an ltrace to my program, hopefully it'll yield some data. Otherwise though, that site is a good resource!
