I happened to look at the Disk tab in BOINC Manager. Most projects had a couple of hundred k. I was somehwat suprised to see the usage of LHC. My system, right now, has just a single LHC@Home work unit on it, yet the LHC disk usage is 7.64 GB. Is this actually in use? Are these files base data for applications? Am I seeing a failure to clean up properly? Wave upon wave of demented avengers march cheerfully out of obscurity into the dream. |

If you have run vbox tasks then that is yes. The disk image files *vdi are very big. I don't have any LHC tasks in my queue at the moment and LHC uses > 8 GB of disk. |

This is normal for LHC@home. For each subproject that needs VirtualBox you have a huge vdi-file that's copied to a slot folder creating a virtual Linux-machine including most used science software, libraries etc. When you have several VM-tasks running and you would suspend them all with 'Leave application in memory' set to OFF, the used disk space for LHC@home could even extend the 20GB. Remark: Suspending all VM-tasks at once (or shutdown BOINC-client) with many VM's running is not a good idea. Best is to suspend them first one after another with 1 minute interval to get the VM properly stored to disk. |
