Workshop on Parallel Code Optimization
Workshop on Parallel Code Optimization
On Thursday, March 16, 2017, KAUST Supercomputing Lab(KSL) is organizing a workshop on Parallel Code Optimization in partnership with Seagate, Intel, and Cray.
In the morning session, Seagate, world leader in storage solutions, is presenting the best practices for parallel I/O. The ClusterStor Lustre parallel file system is designed to provide high performance by maximizing parallelism and avoiding bottlenecks. Understanding the file system tuning options and application I/O design can help in achieving the best results for different usage cases. This training will focus on the interaction of the file system and application, as well as issues in programming for parallel I/O. It will cover the architecture, general parallel I/O models, file system tuning, I/O tracing, MPI-IO usage, and general best practices.
The afternoon session will be dedicated to code optimization where KSL CS team, Seagate, along with Intel and Cray application engineers will help users to tune and optimize their codes for computation, scalability and I/O: bring your codes and problems.
We are looking forward to seeing you there.

Rex Tanakit is leading the Performance and Systems Engineering group at Seagate Cloud Systems , a leader in the clustered storage and parallel file system. He interacts daily with researchers and scientists in the high performance computing (HPC) area. As CPU’s capability and speed increases, the performance bottleneck shifts to I/O - how fast data can be moved in and out of CPU. This is Rex’s current focus. Prior to joining Seagate, Rex was a Vice President of Engineering at Panasas for nearly 10 years and Director of Engineering at SGI for 12 years. He was responsible for Performance Engineering and benchmarking. Rex received his BS in Chemical Engineering from UC San Diego and MS from UCLA. |
