Subject: wrong amount of memory returned
Date: Tue, 8 Jul 2014 11:42:48 -0400
To: bug-Sys-MemInfo [...] rt.cpan.org
From: Robert William Leach <rleach [...] genomics.princeton.edu>
Hi, Was looking for a module to determine the total amount of system memory and tried out Sys::MemInfo. However, I noted that it says I have 4 gigs when I have 16: perl -e 'use Sys::MemInfo qw(totalmem);print "total memory: ".(&totalmem / 1024 / 1024 / 1024)."\n";' total memory: 3.99408721923828 system_profiler | grep " Memory:" Memory: 16 GB I thought I would report it as a bug. Best, Rob Robert William Leach 133A Carl C. Icahn Lab Lewis-Sigler Institute for Integrative Genomics Princeton University Princeton, NJ 08544

I see the same problem on a macbook: $ perl -e 'use Sys::MemInfo qw(totalmem);print "total memory: ".(&totalmem / 1024 / 1024 / 1024)."\n";' total memory: 3.77576065063477 $ perl -E 'say `sysctl -n hw.memsize`/1024**3' 16
