Overview
What this challenge is about.
Profile an MPI weather model on AWS, fix scaling bottlenecks, and benchmark strong scaling to earn a verifiable certificate.
The scenario
The startup (Series A, 3 insurer customers + 2 utility customers, refresh cadence is part of the SLA) cannot deliver the SLA without scaling past 128 ranks.
The Brief
What you'll do, and what you'll demonstrate.
Diagnose and fix an MPI weather-model scaling collapse so that strong-scaling efficiency exceeds 60 percent at 1,024 ranks on AWS ParallelCluster.
Earning criteria — what you'll demonstrate
- Profile MPI collectives with mpiP + Score-P at scale
- Apply communication-computation overlap with non-blocking MPI
- Configure EFA-enabled clusters for RDMA-aware MPI transport
- Benchmark strong scaling and parallel efficiency rigorously
