OSG has limited support for large memory jobs. By default, 2 GB of RAM is assigned to a job. To request more memory, simply use the HTCondor request_memory attribute in your submit file. The default unit is MB. For example, the following will request 12 GB:
request_memory = 12000
Alternatively, you can define a memory request using standard units
request_memory = 12GB
Note that there is only a small number of resources available for large memory jobs, so longer than average queue times can be expected for these jobs.
