HPIO

HPIO is a benchmark, which lets you test reads and writes to and from noncontiguous datalayouts.

Usage

You can set a great deal of flags to finetune the benchmark. To see them all run

mpirun -np 1 hpio -h

Example Output

For example runnning mpirun -np 4 ./hpio -d tmp -o output -a 0 -b 111 -n 1001 -m 111111 -O 11 -A 1 -v2 results in the following output

Filling in parameters which have not been specified by the user...
** Initializing filename prefix to 't'
** Initializing default region count = 4096
** Initializing default region size = 8
** Initializing default region spacing = 128
** Initializing default reps = 1
** Initializing default rep max time = 600.000000
** Initializing to use default aggregator count
** Initializing to use 1 second wait time
** Initializing to use fsync
** Initializing to use INDIVIDUAL fsync method
** Initializing to use VECTOR pattern type
** Initializing use of partial generate file option if necessary
** Initializing to not keep created files that have been read
** Initializing to use persistent file realm size of 4194304
** Initializing to use different files per run
** Initializing cache size of 2 GBytes
** Initializing cache flush off
** Initializing enable resume off
** Initializing to not estimate space
** Verify forces wait time to 0.
** Warning: Two phase I/O using PFRs should use the 'same file mode' to open the file on the first repetition and close the file on the last repetition.  It operates on the same file (r0) with all reps on a given access pattern. PFRs may not work on your system if your MPI-IO implementation does not support it.
** Warning: Two phase I/O using PFRs will not perform well here since every repetition uses a new file.  For good PFR performance set the same file parameter to be 1.
