Setting Up a Cromwell VM
My group is interested in setting up a dedicated Cromwell VM and would like advice on storage, cpu, and memory recommendations for this. We'll be running a number of different pipelines on this VM including a gatk pipeline. Would anyone be able to make a recommendation on any of the following?
OS: RHEL 6 vs 7? Any issues going with 7 with Cromwell.
How many CPUs? We can request up to 24.
How much memory? We can request up to 32gb.
How much storage space. We can have from 80gb to 500gb.
Obviously we don't want more of all of these things just for the sake of having more, but we want enough to run pretty much any pipeline we develop without problems. Any advice would be appreciated.
