Subject: memory usage
Date: Wed, 23 Mar 2016 11:52:20 -0500
Hi all,
When I run build (crimap2.507) on linux, it barely uses any memory on my
machine - top reports 0.1 for %MEM. Right now we are testing using 60+
nuclear families with 600+ total animals. The low memory usage persists
whether I use dozens, hundreds, or thousands of markers (SNPs). As a side
note, running fixed with the same dataset uses at least 6.0 %MEM. I have set
nb_our_alloc to 20Gb (20000000000) in the .par file, and
MAX_PRODUCT_CACHE_MEMORY to 20Gb (20000000000LL) in the defs.h file before
compiling. I did not set any of the other parameters in the defs.h file
because I don't really understand what they do. My rig has 96Gb of memory and
6 cores. Just wondering if this is to be expected or would you recommend
changing any of the settings in defs.h or something else?
Thank you.
