This table shows timing results for examples/couette.x (dt = 0.04 and a 32 x 33 x 32 grid). The "time" column shows the total execution time as measured by the Unix "time" command (e.g. run "time ./couette.x"; the execution time is the sum of the returned values of user and sys times). Speed is defined by (fastest time)/time. name arch -march Ghz L2 bmips time speed ============================================================================= komplex amd-duron athlon 1.0 64 1994 491 0.13 prime pentium3 pentium3 0.93 256 1863 468 0.14 akbar pentium4m pentium4 1.2 512 2395 436 0.15 akbar pentium4m pentium4 1.7 512 3394 345 0.19 light pentium4 pentium4 2.4 512 4793 218 0.39 learn pentium4 pentium4 2.4 512 4800 211 0.30 zero opteron246 athlon64 2.0 1024 4000 94 0.68 harder opteron248 athlon64 2.2 1024 4394 89 0.72 tansen athlon64-X2 athlon64 2.4 1024 4800 85 0.75 love athlon64-X2 athlon64 2.4 1024 4800 83 0.77 pace16 xeonE5345 nocona 2.3 4096 4667 64 1.00
