Posted 4 Mar 2018 by mrbenjamine20 Post: Thank you! I have updated my preferences to show the computers, any input would be appreciated! Also, I have modified my preferences to 4 CPUs and the servers have already queued up a couple 4CPU ATLAS job. We will see how the 4CPU job runs over the next few days! Thanks again for the suggestions! |

Posted 3 Mar 2018 by mrbenjamine20 Post: Hello, I am running a couple of servers with dual E5-2680v2 processors, which have a total of 40 logical cores with hyperthreading and its taking the 8CPU ATLAS simulations about 2 days to complete. They seem to complete successfully from what i can tell, but it looks like in the first 20 hours or so it will complete 90% of the job and then it takes another day to complete the remaining 10% or so. The CPU usage always seems to be pretty low (under 20% of total CPU with 5 Atlas 8CPU jobs running) and i don't see any other bottleneck on the server. I guess my questions are- 1) is this normal and just how the project runs? 2) is there something i can look at to determine a bottleneck? 3) is there any type of tweaking or over-provisioning so i can allow other project to utilize the CPU since its low? I really like contributing to this project and appreciate any input or suggestions! |
