This new version provides HTCondor 8.4.8 using the standard CernVM production distribution. It should finally solve the suspend/resume problems and is half the size of the previous image. Multi-core has also been enabled. |

I think it's a bad idea to run 8 CMS-jobs in one 2048 MB Virtual Machine. The task didn't succeed: 2016-08-08 11:52:54 (7128): Guest Log: [INFO] CMS application starting. Check log files. 2016-08-08 11:59:15 (7128): Guest Log: [ERROR] No jobs were available to run. 2016-08-08 11:59:15 (7128): Guest Log: [INFO] Shutting Down. 2016-08-08 11:59:15 (7128): VM Completion File Detected. 2016-08-08 11:59:15 (7128): VM Completion Message: No jobs were available to run. Multicore VM's do not get jobs or just coincidence. 2 single core CMS-VM's are running cmsRun. |

The memory scaling configuration hasn't been implemented. It was tried with Theory previously but was pulled as there was a problem. It also looks like it can't be done per application. |

I just did a project reset, but i am getting a 47.20 vbox 64 task. EDIT> and it is the same .vdi file as before. |

The CMS app fails if the VM runs on more than 1 core and the standard setting of 2048 MB RAM. A VM running on 2 cores (configured via preferences page) and 3300 MB RAM (configured via app_config.xml) started fine and is currently running 2 jobs. The RAM settings are lend from ATLAS and may be to high for CMS. What are the minimum RAM requirements for CMS? |

What are the minimum RAM requirements for CMS? I think for GRID work we currently quote 1.5 GiB/core. For some analysis tasks we need more than that, but for the pure Monte-Carlo stuff that we have to run here (can't access stored data to do analysis) that should be more than adequate.

I had a four core task fail a 5GB,but works at 5248MB (5GB+128MB) I think, it is important to know exactly, how much memory is needed. |

This new version provides HTCondor 8.4.8 using the standard CernVM production distribution. It should finally solve the suspend/resume problems and is half the size of the previous image. Multi-core has also been enabled. I had a Linux box on 7.2.33 that was having kernel panic trying to run the multicore tasks. I finally got it upgraded to 7.2.42 but it still kernel-panics. My other Linux machines also fail on CMS and Benchmark. I've shut them down.
