I/O profiling and optimization

In computing, I/O bandwidth is just as much of a consumable resource as CPU and memory. While on an individual scale on one's own computer, this is often not the most pressing consideration, on a cluster with shared storage (or very intensive individual projects) it is actually very important to consider. This talk presented lessons and tools that RSEs should have in their toolbox, as we have learned at Aalto Scientific Computing over the years
