Dirk, PowrSym has already been tried on the PowerPC and the results were not great. I have not tried it on the imac yet, but will. It would be wonderful if it were possible to run it on an imac at anywhere near PC speeds, but I sincerely doubt it will be fast enough. PowrSym is a very large (needs 80meg of ram) FORTRAN program with long run time (an hour or so on a P2 400). The model is mostly doing complex floating point arithmetic on very large multiple dimensioned arrays. Thus the L2 cache and the bus speed are very important factors in execution speed. If you or someone else would like to run a benchmark with PowrSym, the system requirements are: 96 meg memory 500 meg disk space Fortran compiler for imac Based on other comparisons, I expect the imac to perform about like a 233 mmx running PowrSym which more than two times slower than a p2 400. Would make me very happy for someone to prove me wrong on this as I am always looking for faster processors.
