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.
