Re: RTS option -A affecting cpu-core usage?

2013-10-08 Thread Daniel Trstenjak
Ok, I think I got it. The cpu-cores are spending most of their time doing GC, by reducing the GC time the cpu-cores don't have anything left to do. Seems like a really great parallel algorithm ;). Greetings, Daniel ___ Glasgow-haskell-users mailing li

RTS option -A affecting cpu-core usage?

2013-10-08 Thread Daniel Trstenjak
Hi all, I played around with a parallel algorithm and tried to get the GC time down by specifying the RTS option '-A'. But if I'm specifying '-A' than also the usage of the cpu-cores seems to change. Without '-A' I'm getting a total cpu-core usage of '4.44s', with '-A' I'm getting only '1.67s'.
