Re: [Gems-users] Wind Tunnel or GEMS?

Ruby can model NUMA timing.  The issue is whether or not your operating 
system can take advantage of it.  For the target we use, Simics thinks 
all the memory is on the same board, so Solaris doesn't do any 
NUMA-aware memory allocation.  You can configure Simics to put memory on 
different boards.  I'm not sure what Solaris will do however.
