c - CUDA Parallel Nsight local debugging on a GTX 590 -

is possible local debugging using parallel nsight on gtx590 on windows 7? understand local debugging require 2 gpus. 590 has 2 gpus cannot work. error message:

parallel nsight debug local debugging failed. nsight incompatible wpf acceleration. please see documentation wpf acceleration. run disablewpfhardwareacceleration.reg in nsight installation.

i have looked @ documentation wpf acceleration , used file "disablewpfhardwareacceleration.reg" disable wpf acceleration - i've checked using regedit , reg_dword set 1, showing hardware acceleration has been disabled. have set "wddm tdr enabled" "false" in nsight monitor options.

i have disabled sli mode through nvidia command panel selecting 'disable multi-gpu mode' in 'set multi-gpu , physx configuration' tab.

using code:

int devcount; cudagetdevicecount(&devcount); printf("cuda device query...\n"); printf("there %d cuda devices.\n", devcount);

outputs message

cuda device query...

there 2 cuda devices.

this indicates 2 gpus in gtx590 viewed 2 separate cuda devices.

despite of still getting above error.

after disable wp acceleration, did restart scheme or nsight monitor or restart applications using wpf hardware acceleration?

if 1 or more applications running wpf hardware acceleration , run .reg file, still have issues until applications restarted.

after disabling tdr timeout, need restart computer take effect.

also did disable sli on gtx 590? if not, can't local debugging on it. please ensure gpu you're debugging on not have output display attached it.

the gtx 590 based on gf110 architecture. should work fine nsight 2.0 + 270.81 driver or 275.33 driver.
