 |
|
Hi,
I'm trying to use the pgcollect command to profile a CUDA program. I get this error for the matmul program as well so I'll use that to illustrate. The source code is here http://www.pgroup.com/lit/samples/matmul.CUF
I compile my program using:
| Code: | | pgfortran -fast -Minfo=ccff matmul_CUDA.CUF -o matmul_CUDA |
This works fine (I can run this executable with no problems). When I try to profile it using:
| Code: | | pgcollect -cuda matmul_CUDA |
I get the following error:
target process abnormal termination: Error: ACCESS_VIOLATION in target program: Exception
no profile generated
I really need to be able to profile my code so if anyone can help that'd be great :)
I'm running Win XP 32bit and using NVIDIA GeForce 210 (compute v1.2)[/url] |

I'll try to reproduce the behavior you are seeing.
In the meantime, you might try
| Code: |
pgcollect -cuda=gmem,cc12 matmul_CUDA
|
to see if things work any better.

Thank you for the reply. Unfortunately I have already tried that with no luck.
There's plenty of room on the Device for the arrays so it's not like there's memory issues. I'm pretty stumped to be honest... |

I haven't been able to reproduce the behavior you are seeing here, although unfortunately I don't have the exact configuration you are using.
In order to make progress on this, please send an email to trs@pgroup.com. Refer to this User Forum thread (http://www.pgroup.com/userforum/viewtopic.php?t=2442) and ask that a TPR be filed and assigned to "donb".
Then, if you are willing, I will contact you and we can work out a plan to debug this problem.
thanks
