The National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory (LBNL) and Argonne Leadership Computing Facility (ALCF) are working with Codeplay Software to enhance the LLVM SYCL GPU compiler capabilities for Nvidia A100 GPUs. The collaboration is designed to help NERSC and ALCF users, along with the HPC community in general, produce […]
Spotting HPC and Exascale Bottlenecks with TAU CPU/GPU/MPI Profiler
February 15, 2021 by
Programmers cannot blindly guess which sections of their code might bottleneck performance. This problem is worsened when codes run across the variety of hardware platforms supported by the Exascale Computing Project (ECP). A section of code that runs well on one system might be a bottleneck on another system. Differing hardware execution models further compound the performance challenges that face application developers; these models can include the somewhat restricted SIMD (Single Instruction Multiple Data) and SIMT (Single Instruction Multiple Thread) computing for GPU models and the more complex and general MIMD (Multiple Instruction Multiple Data) for CPUs. New software programming models, such as Kokkos, also introduce multiple layers of abstraction and lambda functions that can hide or obscure the low-level execution details due to their complexity and anonymous nature. Differing memory systems inside a node and differences in the communications fabric that connect high-performance computing (HPC) nodes in a distributed supercomputer environment add even greater challenges in identifying performance bottlenecks during application performance analysis.

Reading the Intel Tea Leaves: Pat Gelsinger’s HPC Paradox
January 21, 2021 by
As he takes charge of Intel, CEO Pat Gelsinger faces a paradox: his new company is both troubled and a revenue geyser; if Intel is to continue its historical growth rates, he’ll need the skills of a corporate turnaround artist. These contradictions surely apply to Intel’s position in HPC/AI/data center server processors, where the company […]
