Hello, thank you for posting these results. One question: on the External Flow over a Formula-1 Race Car (f1_racecar_140m) benchmark what are the 3 seperate numbers?
32 392 s 16 402 s 12 474 s Thanks again |

what are the 3 seperate numbers?
Number of used Cores Update 2x E5 2670 0 @ 3 gHz // PC 12800 External Flow Over an Aircraft Wing (aircraft_2m), single precision 100 iter SMT on 16 // 226 sec ---- External Flow Over an Aircraft Wing (aircraft_14m), single precision 10 iter SMT on 16 // 207 sec Speedup only +30% // PC 12800 -> PC 19200 + 50 % /// Scaling 1,5^0,66 with Memory Bandwidth |
