New hardware for Oases: how much memory?

[okulev]

Hi,

I'm working on RNA-Seq data from Illumina GA. It's 60M reads. I tried with a machine with 46G but it wasn't enough (Linux OOM killer activates), and even adding swap space up to 100G total (phys+swap) didn't help. So if I search for new hardware, what amount of memory would you suggest?

To better select the next machine you'll buy, I suggest you test your workflow on a cr1.8xlarge (244 GiB of memory) instance in the cloud.
