[PVFS-users] PVFS error at client side

[Tajendra Vir Singh]

Hello Rob,

The following is the configure line which I used at the first time:

./configure --prefix=/u/7day/tvsingh/mpich -c++=icc -cc=icc -f77=ifort
-f90=ifort -lib="-L/u/systems/pvfs/lib/ -lpvfs+nfs+ufs"
-cflags="-I/u/systems/pvfs/include" --with-romio=-file_system=pvfs+nfs
-rsh=ssh --enable-debug  |& tee c.log

Just now I got the pvfs system along with the recent patch from you. I am
trying the same above mentioned switches in configuration of mpich-1.2.5-2.
Will let you know the results.

Thanks,

I see.  Could you give us the configure lines for MPICH?  Thanks,

Rob
