Video: Debugging HPC Applications at Massive Scales
by Rich Brueckner from Inside HPC & AI News | High-Performance Computing & Artificial Intelligence on (#KM1S)
In this video, LLNL scientists discuss the challenges of debugging programs at scale on the Sequoia supercomputer, which has 1.6 million processors. "Bugs in parallel HPC applications are difficult to debug because errors propagate among compute nodes, programmers must debug thousands of nodes or more, and bugs might manifest only at large scale."
