We encourage our fourm members to be more involved, jump in and help out your fellow researchers with their questions. GATK forum is a community forum and helping each other with using GATK tools and research is the cornerstone of our success as a genomics research community.We appreciate your help!

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.

CPU usage

Happy Friday!

I am running GATK on a shared LSF cluster but have unintentionally run afoul of the admins due to resource use. I am running the GATK commands with 'java -Xmx4g -jar $GATK' and am not using -nt or -nct, but CPU usage is exceeding the resources requested which are 1 vCore and 6G memory. I am now running the same commands on our lab server and do indeed see that CPU usage reaches as high as 800% at times. Is there a way to limit the CPU resources claimed by GATK tools, or alternatively a way to anticipate its actual needs so that I can request an appropriate number of CPUs?

Much thanks,
