Purpose:
Feature Changes
Description:
Okay, I needed to add in more parameters so that the user can modify
how things are supposed to work with the PIO programs. Also needed
to change the algorithm a bit to make these work. And needed to add
in timing for the READ option.
Solution:
Added the above things. The parameters took a major rewrite of the
command-line parsing stuff. Here's the usage statement:
usage: pio_perf [OPTIONS]
OPTIONS
-h, --help Print a usage message and exit
-d N, --num-dsets=N Number of datasets per file [default:1]
-f S, --file-size=S Size of a single file [default: 64M]
-F N, --num-files=N Number of files [default: 1]
-H, --hdf5 Run HDF5 performance test
-i, --num-iterations Number of iterations to perform [default: 1]
-m, --mpiio Run MPI/IO performance test
-o F, --output=F Output raw data into file F [default: none]
-P N, --max-num-processes=N Maximum number of processes to use [default: 1]
-p N, --min-num-processes=N Minimum number of processes to use [default: 1]
-r, --raw Run raw (UNIX) performance test
-X S, --max-xfer-size=S Maximum transfer buffer size [default: 1M]
-x S, --min-xfer-size=S Minimum transfer buffer size [default: 1K]
F - is a filename.
N - is an integer >=0.
S - is a size specifier, an integer >=0 followed by a size indicator:
K - Kilobyte
M - Megabyte
G - Gigabyte
Example: 37M = 37 Megabytes
Platforms tested:
Linux, but not fully finished...
