We have two papers that will appear at this year’s ACM/IEEE International Conference for High-Performance Computing, Networking, Storage, and Analysis, a.k.a., “Supercomputing” or “SC”, to be held in New Orleans in November, including one by Aparna and another that is a Gordon Bell Prize Finalist!
The first paper is Aparna’s major improvement to the within-node multicore scalability of our fast multipole method (FMM), introduced in one of our IPDPS papers earlier this year. This paper includes detailed analyses that we imagine will be useful to both other multicore software practitioners and performance tool builders.
The second is a Gordon Bell Prize Finalist, led by Abtin Rahimian, Prof. George Biros, and the CSELa lab at GT, with an assist from HPC Garagers, Aparna, Aashay, Logan, and Rich. This paper presents MoBo (“Moving Boundaries”), a blood flow modeling code that performs the largest and most physically accurate computer-based simulation of red blood cells flowing in plasma that has every been run to date. It achieves 0.7 Petaflop/s on over 200k cores, and is portable to hybrid distributed memory multicore+GPU systems. It uses the scalable and tuned FMM as one of its two major computational components.
