Hi,
I configureed my PVFS2.7.1 server on my IBM thinkpad laptop, which works under
ubuntu8.10 and so does the client. Now I use pio-bench to take simple stride
PVFS I/O trace and it works fine, the thing is I must set the number of process
to 1 when I running mpiexec, if I set the number of process more than 1 it
fails and tips like below:
gxwan...@wangdi:~/Desktop/pio-bench$ sudo mpiexec -n 1 ./pio-bench
[sudo] password for gxwangdi:
File under test: /mnt/pvfs2/ftpaccess
Number of Processes: 1
Sync: off
Averaging: Off
the nested strided pattern needs to be run with an even amount of processes
gxwan...@wangdi:~/Desktop/pio-bench$ sudo mpiexec -n 4 ./pio-bench

The MPI works fine as I have verified it using hostname command. My
pio-bench.conf is like below:
Testfile "/mnt/pvfs2/ftpaccess"
#TestFile "/home/gxwangdi/Desktop/ftpaccess"
OutputToFile "/home/gxwangdi/Desktop/pio-bench/results/result"
<ap_module>

</ap_module>
<ap_module>
ModuleName "Nested Strided (write)"
ModuleReps 3

</ap_module>
<ap_module>
ModuleName "Nested Strided (read-modify-write)"

<ap_module>

ModuleReps 3
ModuleSettleTime 5
</ap_module>
<ap_module>

</ap_module>
As I can not find the system log file for pio-bench somewhere in the directory,
I do not understand what the problem is.
Appreciate your responses.
