I have been running this program successfully before but some copy
operation from /usr/ directory has caused this error.
The program runs fine on the cores of the same machine.
libhdf5.so.7 is also present.
[pmdtest_at_pmd HadGEM]$ mpirun -np 32 -hostfile hostlist rca.x
rca.x: error while loading shared libraries: libhdf5.so.7: cannot open
shared object file: No such file or directory
