Dear Mat,
I have sent a note to customer service for follow-up.
Since this is bit critical for us, can you please let us know if there is a workaround or quick fix for this problem.
Keep us posted on this thread. |

Hi Praveen,
I added a note and increased the priority. I'll try and keep an eye on it for any updates. Note, I made a typo above. I logged this as TPR#19346, not 19033.

I've had some exchanges with engineering and we found a workaround. Put your kernel launch in a critical section.
| Code: |
!$OMP CRITICAL
call ProcessArray_Kernel_1<<<numOfBlocks, threadsPerBlock>>>(VAR_1_D)
!$OMP END CRITICAL
ierr=cudaThreadSynchronize()
|
Hope this helps,
Mat |

Thanks Mat,
Workaround works. But as you know it slows down our performance. Will be waiting for the fix. |
