SUMMARY:Pure:  Evolving Message Passing To Better Leverage Shared Memory w
 ithin Nodes
DESCRIPTION:James Psota and Armando Solar-Lezama (Massachusetts Institute 
 of Technology (MIT))\n\nPure is a new programming model and runtime system
  explicitly designed to take advantage of shared memory within nodes in th
 e context of a mostly message passing interface enhanced with the ability 
 to use tasks to make use of idle cores. We use microbenchmarks to evaluate
  Pure’s key messaging and collective features and also show application sp
 eedups up to 2.1x on the CoMD molecular dynamics application. Overall, Pur
 e offers improved performance by aggressively leveraging modern shared mem
 ory nodes with a programming model that will be familiar to MPI programmer
 s.\n\nTag: Accelerators, Artificial Intelligence/Machine Learning, Algorit
