Parallel Postmark Benchmark

Renaud Lachaize and I have modified the well-known Postmark v1.5 filesystem benchmark to run on a cluster using MPI, in order to measure cluster/parallel filesystem performance. Currently it has been successfully used to measure PVFS2, GFS and Lustre.

For experimental results with parallel postmark please check out my publications or the paper “A Comparative Experimental Study of Parallel File Systems for Large-Scale Data Processing” by Zoe Sebepou, Kostas MagoutisManolis Marazakis, and Angelos Bilas, presented at the USENIX LASCO ‘08 workshop.

Parallel Postmark has been implemented and tested on Linux with MPICH but should run unmodified on other Unices, since it uses standard Unix library calls. The code was publicly released in June 2008.
