Error using fnearneigh_gpu #19
Comments

Hi @dpdarrow , |
|
Thanks. I was able to find improvements from passing the compute flags. I realized that I am getting errors from running make in the cuda directory. Unfortunately, I am getting a reference error:
|
|
I saw the other post by @samuelandjw and found his linking fix of removing extern C from gpuKnnLibrary.cu, which seemed to solve the compilation issue. |
|
I finally determined that the major issue was kernel interruption from the OS on a nondedicated GPU last year. I upgraded to a new computer, and unfortunately, after fixing everything that had been a problem in the past, I am now receiving the same error.
Error in TEcallGPUsearch (line 313) Error in TEsurrogatestats_ensemble (line 880) Error in TEfindDelay (line 57) Error in InteractionDelayReconstruction_calculate (line 115)
console: invalid device function current cuda library is 8 and the dedicated Gpu is P5000 Any thoughts or help would be greatly appreciated |

Hi,
At least for the Pro cards from nVIDIA you can set them to belong
exclusively to the compute process (using nvidia smi) - no display,
then, of course (we run our cards in headless servers only).

See my answer here: #27 |
I am working on a huge dataset and having trouble getting the gpu script working. I was able to solve library issues, but I am stuck on this error:
TEprepare.m - line 934: Optimal tau for this dataset is: 0.39
TEprepare.m - line 946: Optimal dimension for this dataset is: 8
TEprepare.m - line 1056: Adding TEprepare structure to original data structure
InteractionDelayReconstruction_calculate.m - line 113:

Error in TEcallGPUsearch (line 295)

The error reported in the console is:
invalid device function
I tried recompiling with the latest nvidia cuda, but no luck so far
The text was updated successfully, but these errors were encountered:
