Do you have to right number of nodes/processors in your mpirun
command? It seems that you configured your HPL.dat to use 4 nodes, but
supply another number to the mpirun command.

I don't know if this has to do with the above error. Probably you
should give us your command line on the part of your HPL.dat.
