11th POP Guest Webinar - Implementing I/O Best Practices to Improve System Performance with Ellexus

Monday, September 9, 2019

Bad I/O harms shared storage and limits performance significantly, problems that no amount of extra hardware or cloud spend can fix.

In this 30-minute live webinar, Rosemary Francis, Founder and CEO of Ellexus, explained common I/O problems and best practices to implement easy performance wins. She outlined I/O profiling for improving application performance as well as I/O monitoring for improving HPC system performance through good application deployment. Understanding I/O patterns can give easy wins as often a simple fix can make the biggest difference, but knowing where to look is crucial. Finally, Rosemary demoed I/O profiling tools from Ellexus that provide system telemetry and application performance metrics.

The presentation slides are also available here.
