Hi,
Is there any information about how to enhance the performance POCL on Nvidia gpu hardware ?

[pjaaskel]

Perhaps @isuruf can give a list of known perf. issues and how to tackle them in the code.

[isuruf]

@heweiwill, do you have a specific kernel in mind where the performance is low, or are you looking at improving the performance in general?
If latter, I can think of a few specific things. For eg: pocl uses sin to implement native_sin, but using __nv_fast_sinf is better for performance.

Hi Isuruf,

Thanks very much for your reply! I am looking at PoCL running at arm cpu + nvidia gpu, currently we have to apply "-g -cl-opt-disable" to avoid kernel crash.

Please open an issue with more details about the setup.
