Thanks a lot guys. When I rebuilt everything, it (the total_completed) was all fixed (my bad).
It would be great to probably add the hpio test to the nightly tests. You might want to run the smaller version (hpio-debug) with the -v 1 -d pvfs2:/mnt/pvfs2 options, which will test a whole bunch of stuff. By the way, is the datatype branch going to make it to ROMIO at some point? The major bug I've been trying to fix is using the datatype I/O branch of the PVFS2 ROMIO driver using 2 pvfs2 servers. mpiexec -n 2 ./hpio-debug -o 11 -t 10 -m 1 -n 10 -c 4096 -p 128 -d pvfs2:/mnt/pvfs2 It works fine with posix, list I/O, and collective I/O, just not datatype I/O. Could be something with my ROMIO driver or down inside PVFS2. Hard to say. =) Basically, writes are fine, but reads will hang....as if they never truly complete.
