Abstract:Performance profiling tools are crucial for HPC specialists to identify performance bottlenecks in parallel codes at various levels of granularity (i.e., across nodes, ranks, and threads). Although numerous sophisticated profiling tools have been developed, achieving scalable performance introspection on large scales remains a challenge. This is particularly evident in efficiently writing profiles to disk during runtime and subsequently reading them with constrained computing resources for posthoc analysis. In… Show more
