Requesting resources with an HTCondor job¶

HTCondor enables jobs to specify the minimum size of various machine resources are required to support your job through the following submit commands:

request_disk
request_memory

In general with HTCondor these are optional, with the defaults set according to the local administrator's chosen policy. For IGWN workflows, in order to minimise failures because jobs are matched with unsufficient resources, specifying these commands will become mandatory.

Include units in all resource requests

The resource request attributes should all be given as a string that includes the unit associated with the numeric value, e.g.

request_disk = 100 MB

The unit should be one of: KB (kilobytes), MB (megabytes), GB (gigabytes), or TB (terabytes).

Numeric values without units are interpreted as multiples of the default unit, which is not consistent across the various attributes (e.g. request_disk is in KB, while request_memory is MB).
