== Benchmark programs == 
  * IOR (http://sourceforge.net/projects/ior-sio) has a 'driver' for pnetcdf
  * The FLASH I/O kernel (http://www-unix.mcs.anl.gov/pio-benchmark/code/flash-argonne-20060913.tar.gz) will measure several write-only workloads
  

== Notes and suggestions ==

Be mindful of benchmarks which write large contiguous chunks of data.  While
interesting, it might not be what a scientific application using pnetcdf would
actually do.  

Older versions of IOR triggered a performance bug on some Lustre file systems.
Sometimes slow write performance on Lustre can be fixed by disabling the "data
sieving" optimization.  See HintsForPnetcdf for more information.
