Re: [HTCondor-users] Compute personal variables in sub file

["Fischer, Max (SCC)" <max.fischer@xxxxxxx>]

Hi,

at least on 8.4, it is valid to directly use
	request_cpus = 10
	request_memory = $(request_cpus) * 2048
which gets translated to
	RequestMemory = 10 * 2048
in the job classad.

Cheers,
Max
