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 version. 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. HTH, Greg On 11/01/2013 07:15 PM, tyrrell t wrote:

I couldn't find any information on the subject, and have no hardware to test at the moment, but for a future deployment I need to work with IRIX systems, and I was wondering if chimera is coded to take advantage of multiple MIPS CPUs, or is it strictly a CPU-bound application?

ie: would it run better on a dual-cpu octane system at 600mhz, or a 700mhz uni-processor fuel system? ( or something along this line )
