Hi Lapacker

I'm using Cpdgemr2d in a loop like the following:

                for (ii=1; ii<=K; ii+=1)
                {
                        Cpdgemr2d (1, N, A, ii, 1, descA, PL, ii, 1, 
descPL, ictxt);
                }

K can be as large as a few thousand. Somehow Cpdgemr2d stalls at a 
certain step when K is large (1000+ for example). Any clue why?

Thanks,
Peng
