Automate

The scientific computational work as portable workflows. Automatically locates the necessary input data and computational resources, and manages storage space for executing data-intensive workflows on storage-constrained resources. Learn more.

Recover

From failures at runtime (fault-tolerance). Task are automatically retried in the presence of errors. A rescue workflow containing a description of only the work that remains is provided. Provenance is also captured (data, software, parameters, etc.). Learn more.

Debug

Failures in computations using a set of system provided debugging tools and an online workflow monitoring dashboard. Learn more.
