benchmark campaign shows that optimal HPC configuration is highly solver-dependent.<\/p><p data-start=\"4594\" data-end=\"4987\">For <strong data-start=\"4598\" data-end=\"4614\">OpenRadioss\u2122<\/strong>, the Hpc8a instances deliver a clear performance advantage over Hpc7a across all tested configurations. The benchmark demonstrates strong scaling up to 384 cores, which appears to be the optimal configuration for this specific workload. Beyond that point, scalability becomes less efficient, mainly due to communication overhead and workload-specific decomposition limits.<\/p><p data-start=\"4989\" data-end=\"5239\">For <strong data-start=\"4993\" data-end=\"5006\">OpenFOAM\u2122<\/strong>, both Hpc7a and Hpc8a demonstrate consistent scalability as the cluster expands. However, Hpc8a shows a significant performance improvement compared to Hpc7a, with runtime reductions of roughly one third across the tested scenarios.<\/p><p data-start=\"5241\" data-end=\"5678\">The results also highlight an important architectural consideration: high core density does not automatically lead to the best performance for every workload. While OpenRadioss\u2122 benefits from the available core count, OpenFOAM\u2122 can experience memory bandwidth saturation when fully populating a node. In this case, distributing fewer cores across more nodes can improve performance by increasing the available aggregate memory bandwidth.<\/p><p data-start=\"5680\" data-end=\"5994\">Overall, Amazon EC2 Hpc8a instances show a strong performance uplift compared to Hpc7a and confirm their relevance for large-scale MPI workloads. The study also reinforces the importance of careful HPC tuning, including MPI settings, process pinning, memory management, and workload-specific configuration choices.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2db3d18 elementor-widget-mobile__width-initial elementor-widget-tablet__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"2db3d18\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h4><a href=\"https:\/\/www.doitnowgroup.com\/wp-content\/uploads\/2026\/07\/HPC8a-benchmarking-white-paper-DIGITAL.pdf\">Download the white paper here<\/a><\/h4>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f1235da elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"f1235da\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ee8a534 elementor-widget-mobile__width-initial elementor-widget-tablet__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"ee8a534\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3><strong>Discuss your HPC needs today<\/strong><\/h3><h4>Contact us at\u00a0<a href=\"mailto:info@doitnowgroup.com\">info@doitnowgroup.com<\/a><\/h4>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Download the white paper here Introduction Do IT Now deployed an HPC cluster in the cloud using AMD-based HPC-optimized instances on AWS, in order to benchmark the next generation of Amazon EC2 Hpc instances.
