Understanding -nct and -nt
I am trying to understand GATK's parameters for parallelism:
-nt / --num_threads controls the number of data threads sent to the processor
-nct / --num_cpu_threads_per_data_thread controls the number of CPU threads allocated to each data thread
So, is the following example true?
-nt 8 means you use 8 cores
-nct 8 means you use 8 threads within a single core
