@HPCpodcast: Silicon Photonics – Columbia Prof. Keren Bergman on the Why, How and When of a Technology that Could Transform HPC

Silicon photonics has the potential to transform HPC: it’s a dual-threat interconnect technology that could – if and when it is wrestled into commercial, cost-effective form – move data within chips and systems much faster than conventional, copper-based interconnects while also delivering far greater energy efficiency. Venture-backed start-ups and established tech companies….

Silicon Photonics and the Hunt for an HPC Bandwidth Bottleneck Breakthrough

[SPONSORED CONTENT]  “FLOPS are cheap, moving data is expensive.” In HPC circles this sentiment is heard often. There’s a growing sense that classical HPC systems and the advanced chips that power them are pushing up against their practical limits, that some foundational new technology is needed to build more balanced systems to achieve the next […]

Composable HPC-AI at Scale: The Emergence of Optical I/O Chiplets

The allure of “technology resource disaggregation” – a.k.a., composable computing – doesn’t get old. It’s an ingenious yet common-sense strategy for addressing our increasingly heterogeneous HPC-AI world where no single system can cost-effectively satisfy the range of workloads needed to be kept in play, each workload having its own unique combination of system requirements that would otherwise produce, in a single system, “marooned” resources that sap budgets. Put another way, with a composable HPC infrastructure there are pools of compute, memory, and storage resources enabling the dynamic assembly of customized nodes on a per-workload basis, offering configuration of “Goldilocks” solutions.
