Cutting EKS spend 60%+ with Karpenter and dynamic Spot
The full playbook for moving an EKS fleet to Karpenter and diversified Spot capacity — consolidation, spot interruption handling, stateful workarounds, PDBs, taints/tolerations, the CPU-requests/memory-limits rule, and Graviton.

Rebuilding FUN3D with AOCC + AOCL to unlock GCP H4D
How recompiling NASA's FUN3D CFD solver with AMD's compiler and math libraries — and tuning the MPI and memory path — turned GCP's H4D EPYC nodes into a materially faster, cheaper place to run large aero simulations.
