Lead: Ben Evans
The Hero Run team is tasked with:
- Establishing a process to determine the peak streaming performance of a clustered filesystem (both read and write)
- Describing what the test is doing, and detailing why we chose it over other options
- Providing an optional form to detail the system that was tested (servers, targets, interconnect, clients, etc.)
The Hero Run team is optionally tasked with:
- Establishing a process to determine the peak random I/O performance of a clustered filesystem (both read and write)
- Describing what the test is doing, and detailing why we chose it over other options
- Establishing an algorithm to combine Streaming read+write, Random read+write into a single number.
The Hero Run team is not tasked with:
- Creating a Top500 list
- Determining scaling (though the tests can be used to establish that)
- Comparing vendors offerings, or maintaining a database of results.

Single shared file performance
Tools
For testing standard POSIX-compliant filesystems, IOR will be used along with an MPI infrastructure. IOR is available Here . Client allocation in the cluster is up to the team performing the test.
