AWS HealthOmics Adds Nextflow Resource Fallback Directives for Compute Tasks
AWS HealthOmics now supports Nextflow fallback directives, allowing workflows to automatically switch compute resources when primary instances are unavailable. This capability reduces pipeline failures caused by temporary resource constraints.
AWS HealthOmics has introduced support for Nextflow resource fallback directives, enabling bioinformatics teams to define prioritized lists of compute resources for task execution. When primary accelerator or instance types are unavailable in a region, the service automatically falls back to alternative hardware configurations to maintain execution continuity.

Comparison
| Aspect | Before / Alternative | After / This |
|---|---|---|
| Resource Unavailability Handling | Workflows fail or halt when designated primary instances or accelerators are unavailable | Tasks automatically transition to alternative instance types based on defined priority |
Action Checklist
- Define a fallback priority list in your Nextflow task directives Specify secondary options, such as standard CPU instances, to run when primary GPUs are unavailable.
