[PVFS-users] Pthread on PVFS

Hi,

I'm trying to do a multi-thread(pthread) test on PVFS using PVFS API. It
seems it can't work if the main() has two (or more) threads and each
thread has one pvfs_read(). 
"do-job: IOD_MAJIK_NR does not match
 do-jobs: do_job failed: Invalid argument"

I've read some PVFS documents. It's said pvfsd directly transfer data
with iod after contacting with mgr. Is it the reason that compute node
has two pvfs_read accesses to PVFS and those iods don't know which
access is the destination?

Any hints to solve this?

Thanks

Liu Ming
