Hi Rajeev,
Thanks for your reply.
This is my Macros.Linux file which is for directories and compile arguments.
INCLDIR := -I. -I/usr/local/include -I/usr/include -I${INCROOT} -I/mnt/storage-space/disk1/mpich/include
SLIBS := -L/mnt/storage-space/disk1/mpich/lib -L/usr/local/lib -lnetcdf -llapack -lblas
ULIBS := -L$(LIBROOT) -lesmf -lmct -lmpeu -lmph
CPP := NONE
CPPFLAGS := -DLINUX -DPGF90 -DNO_SHR_VMATH
CPPDEFS := -DLINUX
CC := mpicc
CFLAGS := -c
ifeq ($(CC),pgcc)
CFLAGS += -fast
else
CFLAGS += -DUSE_GCC
endif
FIXEDFLAGS :=
FREEFLAGS := -Mfree
FC := mpif90
FFLAGS := -c -r8 -i4 -Kieee -Mrecursive -Mdalign -Mextend
# -g -Ktrap=fp -Mbounds
MOD_SUFFIX := mod
LD := $(FC)
#LDFLAGS := -L/usr/local/gm/lib -lgm -lpthread
#LDFLAGS := -L/usr/local/gm/lib -lgm
I did use mpif90 and mpicc. Why ??

You need to compile with mpif77 or mpif90, not just f77 or f90.

Hi Rajeev,
I just have a try, delete the mpif.h file in the application directories. But in this way I can not even compile the model successfully.

Make sure there is no mpif.h file in any of the application directories.

Hi Correa,
Thank you for your reply. Meet you here agian, haha
I have reorgnized my questions, and posted it on the CGD forum.
I have edited the related directories of the MPI include files and library after you answered me through the ccsm maillist. However, the "invalid communicator" is still there. I am sure my CCSM3 Makefiles now points to MPICH2 include files and the library directories are also have been changed to associate to MPICH2. Is there any other reason that can lead to this problem?
I said that I can "run" CCSM3 by delete any one of the five components. I infact meant that in this situation I can see these process names by the command "top". But if I run all the five, I can not see these process names with "top", and the error message as mentioned before will appear.
The resolution I use is T31_gx3v5. I asked for two nodes(each node with 16G memory and 16 cpus). But I am not sure whether these resources are enough for CCSM3 running or not.
Thanks for your help.
