[mpich-discuss] 'make testing' fails on a pvfs2 filesystem.

[전경원]

Hi.

I attached the test result of 'src'mpi/romio/'. It seems that the failed
tests are related with the shared file pointer and ordered mode. This time,
I used gfortran-4.3 for the Fortran compiler(i.e. F77=/usr/bin/gfortran
FC=/usr/bin/gfortran ./configure --with-file-system="pvfs2+nfs+ufs"). Other
configurations are the same.

Best regards.
