Hello, I am trying to run IOR on top of PVFS2 using MPICH2. The steps I followed are: -> configure PVFS2 with the flag -with-mpi=<PATH TO MPI INSTALLATION> and install it -> configure MPICH2 with the flag -with-pvfs2=<PATH TO PVFS2 BIN DIR> and install it -> configure IOR to use it with MPIIO
However, when I try to run any benchmark by issuing: mpiexec -n $N_PROCESSES -f /home/ubuntu/machinefile ./IOR -a MPIIO -b $MPIIO_BSIZE -t 4096 -o pvfs2:/mnt/pvfs2/testfile -k -s $SEGMENTS -i $REP I get this error: ** error ** ERROR in aiori-MPIIO.c (line 131): cannot open file. MPI Other I/O error , error stack: ADIO_RESOLVEFILETYPE(774): Specified filesystem is not available which is visible in IOR's output file. I am using orangefs-2.8.6, mpich2-1.2.1p1 and the latest IOR benchmark. Is it because I have to configure PVFS2 Kernel Interface? I am using Linux version 3.2 Any help would be appreciated. Thank you!
