Problem in a Parallel program for a 4 node CLUSTER

hi,
Actually i created a 4 node LINUX 9 cluster using MPICH.
now i have written a simple parallel program ( hworld.c) now on compiling it thru " mpicc -c hworld.c " creates a file "hworld.o" now when i run it thru " mpirun hworld " it doesn't run because the compiling command should also create a file " hworld " in order to run.
Reinstalling MPICH doesn't work.......................

try using "mpicc hworld.c -o hworld"

this should create your executable.
Then run it with "mpirun -v -np 4 hworld"

Hope this is the answer you where looking for.
