I am trying to do something rather exotic. I think I have reached a good point in the process, but now I got stuck.
More specifically, I have a MATLAB program, part of which is very computationally intensive. I have successfully put this part into a MEX file (written in C) and parallelized it using OpenMP. So, the MATLAB part only sets up a bunch of arrays and the time-consuming part is done in the MEX file. Everything fine up to this point.
Now I am trying to offload the code in the MEX file to the Phi that is available on the system and use the parallelized version to run it there. I have managed to insert the offload pragmas into the code and compile the MEX file. But when I try to run it (from within MATLAB of course) I get the following error:
undefined symbol: _intel_fast_memmove
I found the above symbol in libintlc.so.5 and linked the MEX file with it, but I am still getting the same error. I got really stuck here and I am not certain what to do. Is the problem on the host side or the Phi side? In either case, does anyone have an idea what I could try to solve it?
I didn't want to fill this message with a lot of information from compilation and linking commands that might not be necessary to solve the problem. If you think they are required, I can provide them.
