Hi all,<br class="">
<br class="">
For now we are running a Condor 8.2.2 with partitionable slots
configuration.<br class="">
<br class="">
Is there a way to say that, for a job, we want to request twice as
much memory as the CPU number (in G)?<br class="">
For example, if I request 5 CPUs, I would also like to request 10G
of memory.<br class="">
<br class="">
From the documentation, I understood that we can only use directly a
variable that we set. Example:<br class="">
<i class="">ncpus = 10</i><i class=""><br class="">
</i><i class="">request_cpus = $(ncpus)</i><br class="">
<br class="">
Or compute a variable from a ClassAd one. Example:<br class="">
<i class="">arguments = --memory $$([TARGET.Memory * 0.9])</i><br class="">
<br class="">
Is there a way to do something like that?<br class="">
<i class="">ncpus = 10</i><i class=""><br class="">
</i><i class="">request_memory = $$[$(ncpus) * 2048])</i><br class="">
<br class="">
Cheers,<br class="">
Mathieu<br class="">
