ABSTRACT

The need for higher levels of performance in HPC applications is being met today by ever increasing levels of parallel computation. This includes both chip level parallelism via GPU accelerators and multi-core CPU's and system level parallelism which utilizes hundreds or thousands of nodes linked together by high speed networking. Efficient use of such hardware resources requires new algorithms and coding methods. This talk will describe recent work with the RMG electronic structure code developed at NCSU that has enabled performance at the 6.5 PFLOP level on the latest generation of supercomputers. Challenges involved with scaling performance to the exascale level will also be described and potential solutions discussed.
