[Chimera-users] chimera scalability on irix

The last version of chimera that ran on IRIX was version 1.3 from 
December 2008 since IRIX computers stopped being made at the end of 
2006.  That Chimera only uses one CPU.

FYI, it is probably time to replace your IRIX computer for running 
Chimera.  The graphics on a modern PC is faster both computationally and 
graphically than those IRIX computers and is much cheaper to maintain.  
And the latest version of Chimera, 1.8.1, is much better than the 2008 

If you had asked this question in 2006, we would have recommended the 
700Mhz SGI Fuel system, but either system would have been excellent.  
But today the recommendation is to junk the SGI systems and get a 
Windows, Linux, or Mac OS X system.
