Yes, I'm aware of those steps so I'm sure I've done it properly. It's running the jobs on 4C or 2C as specified on the host.

Strangely it was using 4C on the correct hosts. Other hosts I was using 2C. So I guess there is no way to differentiate now for the different hosts of you have to set global preferences.

For some reason, Atlas is using 10200 MB per instance of Atlas, despite an app_config setting it at 6600 MB for a 4 core job. Any ideas why this might be happening?

<app_config>
<app>
<name>ATLAS</name>
<max_concurrent>8</max_concurrent>
</app>
<app_version>
<app_name>ATLAS</app_name>
<plan_class>vbox64_mt_mcore_atlas</plan_class>
<avg_ncpus>4.0</avg_ncpus>
<cmdline>--memory_size_mb 6600</cmdline>
</app_version>
</app_config>

That did the trick, thank you so ever much. I was missing an app_version it appears (this is all still cryptic to me).

Is it also necessary to command line the necessary RAM? I've been having success (finally) running 8C and just letting it choose it's own RAM. The computer has 56 threads and 64 GB of RAM, and I rarely see it approaching using it all.

I was wondering if someone could help me with my app_config. I have read this section pretty thoroughly and cannot see what I've done wrong here. I'd like to limit each Atlas app to 4 CPUs, but it runs with either 8C or 32C (that might be Theory only, can't remember) no matter how I config the application.

Can you see an obvious mistake in this?

<app_config>
<app>
<name>ATLAS</name>
<max_concurrent>8</max_concurrent>
<app_name>ATLAS</app_name>
<plan_class>vbox64_mt_mcore_atlas</plan_class>
<avg_ncpus>4.0000</avg_ncpus>
</app>
</app_config>
