speeding up HaplotyperCaller
I've started to call variants on 200 diploid individuals with a genome size of 160Mb, using HaplotypeCaller and 20 cores. In about 10 hours it's covered the first 600,000 bases, so it looks like completion will take several months. I could potentially use up to 64 cores although this would inhibit other users.
My input parameters are as below. They are probably pretty loose. I plan on hard-filtering variants after this.
Do you have any advice on how to speed this up?
