Hi,
I tried to reproduce your reported behaviour and turned only the sequential
write option on. Both time, on ufs and on pvfs2 I get outputs like:
Now testing: Sequential Write
hints total time(s) MB/s buffer size total bytes
0 0.0066 29.6930 1024 202752
....
0 38.5876 20.7321 4194304 830472192
rank 1 in job 14 elric_55264 caused collective abort of all ranks
exit status of rank 1: return code 13
[cli_1]: aborting job:
>Fatal error in MPI_Info_get_nkeys: Invalid argument, error stack:
>MPI_Info_get_nkeys(115): MPI_Info_get_nkeys(info=0x0, nkeys=0xbfb6bc24)
failed
>MPI_Info_get_nkeys(65).: Invalid MPI_Info
If I changed the test to Sequential Read I get exactly the error mentioned:
cannot create file without MPI_MODE_CREATE
I changed the pio-bench open and added MPI_MODE_CREATE as Rajeev noticed. I
enclosed the additional code line in a patch.
A new run gets this results:
Now testing: Sequential Read

0 0.0648 3.0121 1024 202752
...
0 1.2952 617.6736 4194304 830472192
[cli_0]: aborting job:
Fatal error in MPI_Finalize: Other MPI error, error stack:
MPI_Finalize(220).........................: MPI_Finalize failed
MPI_Finalize(146).........................:

was waiting for all open connections to close
MPIDI_CH3_Progress_wait(199)..............: an error occurred while handling
an event returned by MPIDU_Sock_Wait()
Its the same output if I use a file like /tmp/test or if I use a
pvfs2://pvfs/test. I use mpich1.0.3.
If I miss the pvfs2 prefix the test uses UFS. I assume you have created the
directory locally and set permissions to write/modify it as a user.
Best regards,
julian
