I have a problem with an mpi application that I developped.
On a cluster on which run more than one job, i run a job that after it splits the data to compute by each slave, I collect the resulting data secventialy. The problem is that after all the computing done, while the master receives data from say slave 1, the rest of the slaves should do nothing, but with the top command i can see that my aplication uses 99% on all nodes this period of time also.
Another problem is that if I try to run an mpi application that uses also ncurses as interface... it doesnt work!!
Please Help.
Thanks,
Silviu Homoceanu
