Dell T7500 with two NVIDIA Tesla C2070 and one Graphic card for EM Simulation
So I got good results.
C2070(1EA) : Calculation Time(2,170,112 cell) 1h 9m 21s @ TCC mode
C2070(2EA) : Calculation Time(2,170,112 cell) 1h 7m 37s @ TCC mode
C2070(1EA) : Calculation Time(41,773,900 cell) 2h 42m 24s @ TCC mode
C2070(2EA) : Calculation Time(41,773,900 cell) 1h 43m 58s @ TCC mode
Interesting result; perhaps people are not familiar with the Tesla C2070 cards?
