I’m trying to use Tesla C870 with NVS285 x1.
But when I run samples from SDK 1.0.
Performance is very bad.
GPU time is 58XXmesc // 16.xxMB/sec
CPU tims is 544msec // 171.xxMB/sec
I don’t know how could this happen.
GPU is worse than CPU. >.<
This is my environment
MB:Tyan S2895 nVIDIA nForce Pro 2200 + 2050
CPU:2x DualCore AMD Opteron 285, 2600 MHz
MEMORY:A-Data 2 GB PC3200 ECC DDR SDRAM * 8
C870 in slot 1
NVS285 x1 in slot 3
Both slots are x16.
DRIVER:162.61 (or 162.65 in the TESLA disc)
CUDA toolkit & SDK:1.0 (in the disc)
Are there any possible that I’m running CUDA by 285?
Does any using C870 with other card too?
