Presenter

Vivek Kale is a Senior Member of Technical Staff in the Scalable Modeling and Analysis Department at Sandia National Laboratories. Vivek works on improving performance of scientific codes run on supercomputers with multi-core nodes. During his PhD, Vivek worked under the supervision of Professor William D. Gropp and was a Lawrence Scholar at Lawrence Livermore National Laboratory. Vivek's dissertation work focused on developing lightweight loop scheduling strategies to improve the scalability of bulk-synchronous MPI+OpenMP applications run on clusters of SMPs. He also was involved in work on MPI shared memory extensions model for MPI-3, also known as the MPI+MPI model. Vivek's current work involves performance optimizations that include techniques of auto-tuning and loop scheduling of ptychography solvers intended to run on supercomputers having nodes with GPUs and/or MICs.
