@article {1165, title = {Design and Implementation of the PULSAR Programming System for Large Scale Computing}, journal = {Supercomputing Frontiers and Innovations}, volume = {4}, year = {2017}, abstract = {The objective of the PULSAR project was to design a programming model suitable for large scale machines with complex memory hierarchies, and to deliver a prototype implementation of a runtime system supporting that model. PULSAR tackled the challenge by proposing a programming model based on systolic processing and virtualization. The PULSAR programming model is quite simple, with point-to-point channels as the main communication abstraction. The runtime implementation is very lightweight and fully distributed, and provides multithreading, message-passing and multi-GPU offload capabilities. Performance evaluation shows good scalability up to one thousand nodes with one thousand GPU accelerators.}, doi = {10.14529/jsfi170101}, url = {http://superfri.org/superfri/article/view/121/210}, author = {Jakub Kurzak and Piotr Luszczek and Ichitaro Yamazaki and Yves Robert and Jack Dongarra} }
