Re: [sage-combinat-devel] Terminated jobs on combinat server?
Hi Andrew, I definitely didn't kill them, and the machine hasn't been rebooted in 2 months. Your jobs might have used too much memory and been killed by the Linux kernel. Thanks William, that's probably what happened. I'll try and improve my memory management! I'm sorry your computation where stopped. I have some extremely CPU intensive computations running on combinat. I designed it to run on the CPU cache so that it needs very few memory: It actually runs on 32 core but take less than a MB of memory. I'm watching it on a regular basis and I remember seeing one of your code which had allocated mode than 30 GB. If there were only one it shouldn't pose any problem on combinat. However, there are some virtual machine running and several other memory eating processes.

Hi Andrew, I also had a large job running on combinat. I just checked and it also seems to have disappeared. Too bad! So it might be good to find out what happened!?

We could repartition the new /scratch disk to provide a bigger swap...? On Jun 18, 2013 2:00 AM, Anne Schilling a...@math.ucdavis.edu wrote: Hi Andrew, I also had a large job running on combinat.

[sage-combinat-devel] Terminated jobs on combinat server?
Hi All, I had some (very long and quite intensive but niced) jobs running on the combinat server but they have all been terminated. I'm not sure whether this was done accidentally or because they were hogging resources or for some other reason (although I was monitoring them and they seemed OK). This calculation has been all that I have had time for sagewise for the past few months:( Unfortunately I have lost some of the calculation but luckily I can restart them within a few days of when they died. Before restarting them I thought that I should check to see if I was breaking the usage guidelines or etiquette. Please advise!
