[HTCondor-users] a question about machines in the pool and slots handling

["Valdes, Julio" <Julio.Valdes@xxxxxxxxxxxxxx>]

Hello:

 

I have a condor pool with machines having different numbers of CPUs each (Ex: machine A has 16 cpus, machine B 32 cpus and so on).

The scenario is that I want to be able to somehow specify that only 4 CPUS max must be used from machine A, 10 from machine B and so on.

A more elaborated reformulation of the above would be:

How could I write a ClassAd requirement indicating that from machine A I want to use only slots 3, 4 and 5, from machine B slots 23, 25, 27 and 28, say?.

All of that, within a condor submission file.

Is that possible?.

If so, Could anyone provide an example of a requirement (or rank) statement implementing the aforementioned specification?.

I tried to google this issue in many ways, unsuccessfully. I also went through the condor manuals, but I was not able either to find the answer or to understand the material so that I could construct the answer myself.

Any help would be much appreciated.

Thank you in advance
