WebNov 8, 2024 · We re-evaluated multiple options, such as threading, parallel garbage collection, I/O options and data-level parallelization. Additionally, we considered the trade-offs of using GATK3.8 and GATK4. 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? What actually happens in … See more In computing, a thread of execution is a set of instructions that the program issues to the processor to get work done. 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 WebThis model is a straightforward generalization of previous ones (e.g. PolyBayes, samtools, GATK) which detect or report variants based on alignments.

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.
