Data thread meaning
Maybe this is silly question, but I still don't understand what a 'data thread' means (-nt paramenter). I understand that -nct is the number of running threads that can run in parallel for a given data thread. But in which context can we have several data threads?
I made some tests, and I naively supposed that each cpu-thread would be child of some data thread, but when I execute UnifiedGenotype, all the threads are at the same level (I checked with htop).
Thanks in advance.
