Performance Analysis and Visualization for High Performance Computing Systems
The exponential disparity between the speeds of CPUs and storage systems continues to widen. Data-intensive computations may require hundreds of disks per CPU to utilize modern processors. Even previously CPU-bound workloads are now becoming I/O-bound. Our efforts are focused on finding and fixing I/O performance problems on high performance computing systems by creating a suite of tools to benchmark, trace, profile, analyze, and visualize file and storage systems. This is a collaborative effort between several laboratories:- The Storage Systems Research Center (UC Santa Cruz).
- The Visualization Lab (Stony Brook University).
- The File systems and Storage Lab (Stony Brook University).
