Hero Run Best Practices

Back to the main BWG page

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.

What goes into a hero run? A list of terms and concepts

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.
