Large Memory Jobs

By default, 2 GB of RAM (aka memory) will be assigned to your jobs. However, some jobs will require additional memory to complete successfully. To request more memory, 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 = 12228

You might be wondering why the above is requesting 12228 MB for 12 GB. That's because byte units don't actually scale by 1000 (10^10) like the metric system, but instead scale by 1024 (2^10) due to the binary nature of bytes.

Alternatively, you can define a memory request using standard units

request_memory = 12GB

We recommend always explictly defining the byte units in your request_memory statement.
