CPU to GPU Copying Speed tuning.

Narendra Kumar

Hi,

Is there any way to speed the data copying from CPU buffers which are allocated using "malloc" to GPU accessible memory. currently I am using simple memcpy for copying data.

Thanks & Regards,

Narendra Kumar Chepuri.

    Hi Anthony,

                            Thanks for your response but here I am not using any structures for storing input data, so for solving this Cache issues is there any other way,

    Note: I am just using source pointer as argument using globalid  in kernel I will access the source data which is at particular point.

    Thanks & Regards,

    Narendra Kumar.
