We have a 425T now, and according to the ADUS linpackd.ftn, they run at 2.2 MFLOPS. This is with the Rev 10.8 fortran compiler with the "-opt 4 -cpu mathlib" flags. A DN3500 returns with about .25 MFLOPS, for comparison. Your milage may vary, of course. -- *-----------------------------------------------------------------* | Eric Bratton | The University of Michigan | ericb@caen.engin.umich.edu | #include *
