Claude Science and private AWS HPC compute
Claude Science knows how to connect via SSH to execute work on compute servers and HPC clusters That is good, but not very good. It’s 2026, and who wants to hang an SSH server out on the naked, public Internet? What I really need for Claude Science and my compute … This should be table-stakes […]
Your old AWS ParallelCluster stacks will NOT break in 2026
Note: This post is pure google bait designed to help others who run into the same problem. We hope it helps! We had been advising clients to rebuild older ParallelCluster stacks — the ones whose cleanup Lambdas are templated on python3.9 — by mid-2026, ahead of the published Lambda block dates. Those dates have moved. […]
AWS PCS resolves Licenses length issue
Good news: The 1024-character limit in the AWS PCS custom slurm configuration parameter that enables license-aware job scheduling was recognized by AWS as a “bug” and recently resolved. The new character limit is 2048. TL;DR AWS Parallel Computing Service (PCS) previously capped every slurmCustomSettings.parameterValue at 1,024 characters. The limit applied uniformly through Terraform, the AWS […]
Schrödinger 2026-1 and broken jsc certs
Note: This post is pure google bait designed to help others who run into the same problem. We hope it helps! 16-April-2026: Correction – Schrödinger has documented this issue and a workaround at https://my.schrodinger.com/support/article/629509 You upgraded jobserverd, your functionality tests ran clean on the Slurm side, and a few hours later your scientists started complaining.

License-Aware Cloud HPC: Accelerating Discovery with Schrödinger, Cresset, and Posit
Summary Computational chemistry software licenses are among the most expensive line items in a drug discovery budget. When those licenses run on cloud HPC, poor integration creates problems: idle licenses burn money, contention between researchers stalls work, and GPU-heavy notebook sessions run around the clock even when no one is using them. It’s not just […]
