hi, new to bionic. reading through the info and user manual, i am not sure if I should install the opencl for my cpu. I am running an amd 9590, my NVidia gpu's have it, but my cpu does not. i have downloaded the amd app-sdk v2.8.1 that will install opencl for my cpu but I am not sure if I should or if it is needed.so should I install it or not? and a reason if possible...thank you for any help

Don't bother to install it, not needed for CPUs.

BOINC projects with applications for CPUs will supply ordinary x86 binary executables. They're well understood, and there's no need for an intermediate language interpreter like OpenCL.

OpenCL comes into its own for programming GPUs, but there's still no need to install a separate package: each of the major GPU manufacturers (AMD, Intel, NVidia) supplies OpenCL runtime support in their graphic driver packages.

As far as I know, there are no projects at the moment that have OpenCL applications that run on the CPU only, so you don't need these drivers.

You do need OpenCL/CUDA for the Nvidia card, but support for that is built into the drivers themselves, as long as you download these from the Nvidia drivers site.

By the way, the program's name is BOINC. It's an acronym that stands for Berkeley Open Infrastructure for Network Computing.

very good. thank you for the answers. very much appreciated. I do have the newest NVidia drivers and both cards running in sli have cuda cores and drivers
