[RegCNET] errors in mpi

Dear Bi,
Sorry to bother you again but we still find some errors when trying to run
regcm in parallel mode with more than one processor

If we specify a number of 4 processors, we get

 $ mpiexec -np 4 regcm < regcm.in > salida.out &
[2] 29699
At line 374 of file param.f
Fortran runtime error: End of file
At line 374 of file param.f
Fortran runtime error: End of file
At line 374 of file param.f
Fortran runtime error: End of file

Which seems to indicate that once the first processor starts, the second,
third and fourth processors can not read the param.f file

If we specify two processors, we get

$ mpiexec -np 2 regcm < regcm.in > salida.out &
[1] 29731
At line 374 of file param.f
Fortran runtime error: End of file

The runtime error appears now just once, i. e., the first processor starts
running but
the second one does not start (apparently because it can not read param,f)

Could you help us again ?

Sincerely,    ANtonio Sarmiento G.
