[mpich-discuss] Facing problem while using MPI_File_set_view

[Wei-keng Liao]

Hi, Christina,

Can you try the following temporary fix? I believe there is a bug
in adio/ad_pvfs2/ad_pvfs2_read.c, line 477. Please replace
                 file_lengths[0] = st_frd_size;
with
                 file_lengths[0] = ADIOI_MIN(st_frd_size, bufsize);


I tested you program with this fix and it ran fine.
(I used mpich2-1.0.8p1)
