ECP Announces 2021 Community Birds-of-a-Feather Days

March 1, 2021 – The US Department of Energy’s Exascale Computing Project (ECP) has announced the ECP 2021 Community BOF Days, Birds-of-a-Feather sessions for the high performance computing (HPC) community. BOFs offer various formats (e.g., panels, presentation, roundtable) bringing together people with shared interests and encouraging discussion and idea exchange. ECP’s BOF Days will take […]

ECP: SuperLU Library Speeds Direct Solution of Large Sparse Linear Systems on HPC and Exascale Hardware

HPC and AI technology consultant and author Rob Farber wrote this article on behalf of the Exascale Comuting Project. Lower-upper (LU) factorization is an important numerical algorithm used to solve systems of linear equations in science and engineering.[i] These linear systems of equations can be expressed as a matrix, which is then passed to a […]

Spotting HPC and Exascale Bottlenecks with TAU CPU/GPU/MPI Profiler

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.

ATPESC – Argonne Training Program on Extreme-Scale Computing – Sets March 1 Application Deadline

Argonne National Laboratory said today it has established a March 1 deadline to apply for an opportunity to learn the tools and techniques needed to carry out research on the world’s most powerful supercomputers. Applications are now being accepted for ATPESC 2021 — a two-week training program designed to teach the skills, approaches and tools to design, implement and execute […]

Let’s Talk Exascale: Getting Applications Aurora-Ready

This episode of Let’s Talk Episode from DOE’s Exascale Computing Project is the first in a series on best practices in preparing applications for the upcoming Aurora exascale supercomputer at the US Department of Energy’s Argonne National Laboratory. In these discussions, the emphasis will be on optimizing code to run on GPUs and providing developers […]

Exascale and Beyond: DOE Funds $12M for Adapting Software for Next-Gen Supercomputers

The U.S. Department of Energy (DOE) today announced plans to provide up to $12 million for research aimed at adapting scientific software to run on next-generation of supercomputers. DOE said applications will be open to DOE national laboratories, universities, industry, and nonprofit research institutions.  Funding is to be awarded competitively, on the basis of peer […]

Exascale Computing Project: Researchers Accelerate I/O with Novel Processing Method

January 25, 2021 — Researchers funded by the Exascale Computing Project (ECP) have delivered a novel method that addresses overloaded communication processes that use MPI-IO by adding a second I/O request aggregation layer, according to ECP. Their method, called TAM for two-phase aggregation method, combines data on a node prior to performing additional internode optimizations […]
