OpenCL 1.2 Hydro benchmark problem

I'm trying to benchmark the prototype (cooling system) machine (1 x Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz+ 2x AMD FirePro S9000) in our computing centre using Hydro OpenCL benchmark

Together with the benchmark's author we've tried to analyze the problem which we guess is not freeing memory and system freeze.

At some point application stalls and GPU becomes unreachable.

'aticonfig' shows percentage usage at the level of 0-3% whereas it should be substantially more

Is there any tool I could monitor MEM usage on the GPUs?

Does anyone have experience with Hydro benchmark on AMD GPUs?


The same code is running i.e. on NVidia's K20 smoothly and without problems.

Other OCL tests applications work well.


OpenCL version installed is:


Device OpenCL C version:                   OpenCL C 1.2
Driver version:                            1214.3 (sse2,avx)



Best regards,
