-- GenomeLocParser cache was a major performance bottleneck in parallel GATK performance. With 10 thread > 50% of each thread's time was spent blocking on the MasterSequencingDictionary object. Made this a thread local variable. -- Now we can run the GATK with 48 threads efficiently on GSA4! -- Running -nt 1 => 75 minutes (didn't let is run all of the way through so likely would take longer) -- Running -nt 24 => 3.81 minutes |
