Interesting, what type of computation does the net do? It would be nice if one of the pre-release tests was a benchmark to ensure that recent changes haven't slowed things down (too much).I've been using the SGI compiler on an Octane R10000 @ 250Mhz.(I never installed gcc, so the MIPS compiler just works). The default compilation seems to be n32 rather than 64bit so, I suspect there would be a very significant speedup if one were to use 64bit. According to "man abi", one can change the default compile type by editing the /etc/compiler.defaults file. Maybe I'll get brave this afternoon and try it. It doesn't solve you problem however. Would be better if configure options existed for overiding compiler choice. Richard
