Fix CPU-only runtime for dpcpp-generated executables in custom easyblock for intel-compilers #2457
Conversation
This is needed to run dpcpp-compiled executables on CPUs
TBB is also an internal dependency for the OpenCL shared objects.

1. Use get_tbb_gccprefix from tbb easyblock instead of hardcoding gcc4.8 2. Resolve 'latest' symlink since the embedded tbb version may be different from the compiler version.
To satisfy testing.

First of all the OpenCL runtime needs to be aware of the CPU-only shared object via
OCL_ICD_FILENAMES -> libintelocl.soThe module also needs to set TBB-related variables (the same ones as the old iccifort modules), since the above object links to TBB.
This can be tested using e.g. saxpy from

I haven't tested dpcpp on FPGAs, nor on Intel GPUs (though I can try the one on my laptop, an Intel Corporation UHD Graphics 620 chip).
NVidia GPUs are not supported.
