My group is setting up to run some metagenomic analyses over the next month or so. This is currently running on the instance ubuntu@137.44.59.111. The default 4 cores and 32GB RAM work fine for the assembly stages, but we are going to struggle with building adequate databases for classification.
Would it be possible to upgrade the cores/RAM on this instance? I think RAM between 150-200GB and ~32 cores would work great.
Yep I spotted the kraken build which I have been using. I also intend to use CLARK and kaiju, which need up to 156GB to build and ~60GB to run (in the case of CLARK).
I could probably run the tools okay with the default setup, but is there a way to briefly access more memory for building the databases?
