Gatk multiple threads
WebJun 3, 2015 · In the meantime, what you need to know is that -nct is the number of CPU threads, ie threads that can be run by different cores if you have a multicore CPU, while -nt is the number of data threads, ie number of “clones” of the GATK that are run in parallel on your machine. So nt is based on how many copies you want to run in the same time. WebMost GATK (>=4) tools are not multicore by default. This means that you should request only one core when calling these kind of tools. Some tools use threads in some of the computations (e.g. Mutect2 has the --native-pair-hmm-threads) and therefore you can require more cpus (most of them with up to 4 threads) for these computations.

http://protocols.faircloth-lab.org/en/latest/protocols-computer/analysis/analysis-gatk-parallel.html Parallelism is a way to make a program finish faster by performing several operations in parallel, rather than sequentially (i.e.waiting for each operation to finish before starting the next one). Imagine you need to cook rice for sixty-four people, but your rice cooker can only make enough rice for four people at a time. … See more OK, parallelism sounds great (despite the tradeoffs caveat), but how do we get from cooking rice to executing programs?

In single-threading mode, a program only sends a single thread at a time to the processor and waits … See more Before we get into the different ways of parallelizing work, we need to talk about levels of computing, and by that I mean the computing units in terms of hardware: the core, the machine (or CPU) and the cluster or cloud. 1. … See more If you google it, you'll find that the term scatter-gathercan refer to a lot of different things, including strategies to get the best price quotes from online vendors, methods to control memory allocation and… an indie-rock band. … See more
WebMar 21, 2024 · @DarioS I wonder if you're looking at the JVM garbage collector threads -- by default, Java uses a multi-threaded garbage collector. You can control the number of threads it uses via the -XX:ParallelGCThreads=N argument, where N is the number of garbage collector threads. To pass this option into GATK, use the --java-options argument.
