pocl has some other pre-requirements besides clang/llvm, after installing them you can just build the software as usual:
$ sudo yum install --enablerepo=rawhide llvm-devel llvm clang \ libtool-ltdl
$ git clone$ bzr branch lp:pocl $ bash autogen.sh $ ./configure $ make $ make check
Does these OpenCL implementation permit hardware accelerated operations, or are the kernels executed on the CPU at the moment ?ReplyDelete
Currently pocl as well as clover are supporting CPUs as a compute device.ReplyDelete
But the intention behind clover is to be able to use GPUs via mesa, but there is still much work to do, to reach this functionality.
You need to use proprietary drivers to use GPUs.
