For Planck task, currently the default VM memory is 2048MB. How can I change this?

For e.g. task http://www.cosmologyathome.org/result.php?resultid=53181589 which was just completed, show a 2GB of VM memory set aside. I would like to lower this so that I can run more tasks.

Below is the partial output of the task log file:
Stderr output
<core_client_version>7.6.22</core_client_version>

Here is an example config file from LHC but the command applies.

<cmdline>--memory_size_mb 4800</cmdline>


I'm not sure if its actually needed tho.
