Test-drive the GATK tools and Best Practices pipelines on Terra
Check out this blog post to learn how you can get started with GATK and try out the pipelines in preconfigured workspaces (with a user-friendly interface!) without having to install anything.
libVectorLoglessPairHMM is not present in GATK 3.8 - HaplotypeCaller is slower than 3.4-46!
We are running GATK on a multi-core Intel Xeon that does not have AVX. We have just upgraded from running 3.4-46 to running 3.8, and HaplotypeCaller runs much more slowly. I noticed that our logs used to say:
Using SSE4.1 accelerated implementation of PairHMM
INFO 06:18:09,932 VectorLoglessPairHMM - libVectorLoglessPairHMM unpacked successfully from GATK jar file
INFO 06:18:09,933 VectorLoglessPairHMM - Using vectorized implementation of PairHMM
But now they say:
WARN 07:10:21,304 PairHMMLikelihoodCalculationEngine$1 - OpenMP multi-threaded AVX-accelerated native PairHMM implementation is not supported
WARN 07:10:21,310 PairHMMLikelihoodCalculationEngine$1 - AVX-accelerated native PairHMM implementation is not supported. Falling back to slower LOGLESS_CACHING implementation
I'm guessing the newfangled Intel GKL isn't working so well for us. Note that I had a very similar problem with GATK 3.4-0, in http://gatk.vanillaforums.com/entry/passwordreset/21436/OrxbD0I4oRDaj8y1hDSE and this was resolved in GATK 3.4-46.
