I'll try the MIPS (aka MIPS32) solution - hey, it can't kill anything. There are some subtle differences, but most MIPS64 boards'll run MIPS32 code (I think in a similar way to the way AMD's 64-bit chips also run 32-bit code).
However, for anyone planning a "native" MIPS64 solution, I've found a few technical documents that seem to cover the material wanted: The basic MIPS64 (and MIPS32) specification, instruction set, et al, can be found at: http://www.mips.com/content/Documentation/MIPSDocumentation/ProcessorCores/doclibrary Free registration is required to download the manuals. The Broadcom manual specifically for the SB1 chip and the boards Broadcom uses them in can be found at: http://sibyte.broadcom.com/public/resources/ Although I can't see this being overly useful for OpenMPI, the SB1 also implements HyperTransport. http://www.hypertransport.org/tech/tech_specs.cfm It might be useful if someone was writing some really exotic stuff, though, and I've found it's almost impossible to have too many manuals. ______________________________________________________ Yahoo! for Good Watch the Hurricane Katrina Shelter From The Storm concert http://advision.webevents.yahoo.com/shelter
