1) Message boards : ATLAS application : Computational errors (Message 35108) Posted 29 Apr 2018 by lazarus_long Post: I think I might have it set up now. I'll just have to wait and see. The only thing that has me worried from the cvmfs guide is that cvmfs isn't recognized as a service on. Since the distro has SystemD(erp) I have no desire to troubleshoot it. Now that I know what the issue was (is?) I'll have to find a way to install all of this stuff on sane distro or just turn off the testing WU's and be done with it. One weekend of troubleshooting a project I am donating my computer and electricity to is enough. laz
2) Message boards : ATLAS application : Computational errors (Message 35105) Posted 28 Apr 2018 by lazarus_long Post: My Linux box is failing to complete every task in the ATLAS Simulation 2.54 x86_64-pc-linux-gnu (native_mt) category because of computational errors. I have tried two different distros with 2 different version of boinc and virtualbox. I have gone through Yeti's check list to make sure that my software and configuration are correct. Is there some way that I can check what is going wrong with these tasks and correct it, or it something the LHC staff needs to look into? So far I have had about 20 WU fail in the past two days. I would like to return valid results to the project instead. Otherwise it seems like a waste of bandwidth. laz
3) Questions and Answers : Unix/Linux : Asking for advice about client configuration (Message 32969) Posted 3 Nov 2017 by lazarus_long Post: Hello all. I have a home server with boinc installed and I would like ask how I should configure LHC@home to get the most out of my hardware. My server specs: OS: Ubuntu Server 16.04 LTS CPU: Xeon D-1520 (4 cores 8 threads @ 2.4GHz) RAM: 32GB (registered ECC DDR4 @ 2133MHz) SWAP: 32GB swap space stripped across 4 HDD DISK: 256GB for boinc LV on RAID 10 In addition to LCH@home tasks I do Einstien@home GPU tasks and they take 1 logical CPU to run the GPU. These tasks only run one at time using about 1GB of ram and very litte disk space. So how many tasks should I let LHC@home run given my setup? Please explain your answers or provide links to documentation, that way I learn more than just a number. Laz
