After business hours on Friday, Intel released information on a “streamlined and simplified” data center GPU roadmap with direct impact on HPC and AI. The new plan calls for the discontinuation of the “Rialto Bridge” GPU, which was to have succeeded the Ponte Vecchio chip that itself was delayed several years before shipments began last […]
LLVM Holds the Keys to Exascale Supercomputing
July 12, 2021 by
The recent proliferation of new hardware technologies has galvanized the high-performance computing (HPC) community and created the ability to deliver the nation’s forthcoming exascale-capable supercomputers and data centers. It has also made LLVM-based compiler technology the default gatekeeper to these new systems. LLVM, an open-source collection of compiler and toolchain technologies, serves as a test bed for proposed parallelization extensions (e.g., the interoperability directive in OpenMP 5.1) and as a vehicle to provide production-quality parallel compiler implementations. Johannes Doerfert, a researcher at Argonne National Laboratory, notes that “LLVM is a vehicle to provide performant implementations of OpenMP….
