I don't know enough about HPL to resolve the problem. However, I would suggest that you first just try to run the example programs in the examples directory to ensure you have everything working. If they work, then the problem is clearly in the HPL arena.
I do note that your image reports that you have an illegal entry in HPL.dat - if the examples work, you might start there.
