Nice to see your project's growth.

Well sometimes such issues can happen, and it is good if you can provide some testcase, or the code files from your project which can reproduce the issue here.

Also provide other system details(SDk,DRIVEROS).

Thanks Himanshu,

The problem occur randomly when I try to sort. If you want to test you can download the project and run it. It is directly connected to it.

 

Also, I have 2 other problems:

1 - On the GPU... sometimes it does not work ! Sometimes it works ! I think that the problem is in the 'exclusive_scan_128', but can't find the reason !

2 - I try to sort on 16 bits only, so I simply do 4 loop (and not 8 for 32 bits). But it does not work !

If someone can take a closer look... it will help !

I can confirm this too. Using catalyst 10.6 with the delivered APP SDK on the HD6950 under win7 64bit. I'm using opencl/opengl interoperability in my application. EVERY TIME i've tried to start my application my system got frozen. Downgrading to 10.5 solved the problem.

If you lower a little the clock of your memory + gpu! It wont freeze anymore!

I don't understand what you are talking about !

When I redistribute my software I can't ask peoples to hack anything !

Can you please guide me as to what files i need to download and check, for this problem. I am seeing 42 files in the project and going through them should take quite a time.

Fine,

In the benchmark.cpp file, just launch the :

test_Sort_KV(&context);

Then, the ".cl" file is clppSort_RadixSort.cl

It is the file that cause the problem !

 

Thanks

Solved with Catalyst 11.7. Clean uninstall any previous drivers with "Drive Sweeper" first.
