Re: HPL low performance result.

While in octave, type "edit parallel_performance". At the bottom of the file you'll see

# loop over several cluster sizes
printf("Sample size: %d burnin: %d  maxiters %d\n", T, burnin, maxiters);
for nodes = 0:1
        pea_args{6} = nodes;
        pea(model, model_params, exp_model, exp_params, pea_args);
endfor


Just edit the line "for nodes = 0:1" to increase the maximum number of nodes.
