SUMMARY:Lamellar: A Rust-based Asynchronous Tasking and PGAS Runtime for H
 igh Performance Computing
DESCRIPTION:Ryan Friese, Roberto Gioiosa, Joseph Cottam, Erdal Mutlu, Greg
 ory Roek, Polykarpos Thomadakis, and Mark Raugas (Pacific Northwest Nation
 al Laboratory (PNNL))\n\nThe discussion around "safe'" programming languag
 es has significantly increased in recent years. The White House Office of 
 the National Cyber Director released a report  in February 2024 calling on
  the technical community to work towards proactively reducing attack surfa
 ces in cyberspace, in part, specifically by adopting memory safe programmi
 ng languages. \n  We introduce Lamellar,  an asynchronous tasking and PGAS
  runtime system for HPC written in Rust, one such ``memory-safe'' language
 . We describe the entire Lamellar stack, from network interfaces to safe a
 bstractions such as distributed LamellarArrays and Active Messages. The go
 al of our runtime is to enable end-users to develop entirely safe Rust cod
 e in their applications, limiting the use of any ``unsafe'' code blocks to
  rigorously tested code blocks within the runtime itself. We conclude by s
 howing comparable performance against several C, C++, and Chapel implement
 ations of a subset of the BALE kernel suite while maintaining strong memor
 y safety principles.\n\nTag: Heterogeneous Computing, Parallel Programming
