I am trying to figure out how to set up either in appinfo or cc_config or via the project settings, to restrict ATLAS to running just 1 instance at a time. In project settings I have it set for 8 CPU (16 cores I guess), if I restrict it to 4, then it uses 8 cores? But....how do I go about writing a script that tells ATLAS to only use 8 cores and no more? And let all the other projects here do what they want? ATLAS as a double instance, eats 95% of my memory and uses all 16 cores. Nothing else from BOINC can run while these are grinding away. What are your recommendations? For the moment I can not afford to buy more memory. I was looking at 16 gigs, but that's around 75 Euro. A bit to pricey for me at the moment. |

On the websettings should be : Max 8 CPU, Max 1 Job in app_config: <app> <name>ATLAS</name> <max_concurrent>1</max_concurrent> </app> <app_version> <app_name>ATLAS</app_name> <plan_class>vbox64_mt_mcore</plan_class> <avg_ncpus>8</avg_ncpus> </app_version> I'm not sure how well this play with the other projects, I run my ATLAS in a separate BOINC instance so I can get it to work correctly. |

I have never tried running a second instance of BOINC. I have always kept everything under one instance. But let me try your app_config code first. Thanks for writing that. The idea of a second instance for ATLAS sounds interesting though. |
