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.

Pegasus Research Impact
with No Comments

Pegasus (est. 2001) has been widely adopted by the computational research community, and its performance and usage data have already demonstrated its ability to empower the scientists to seamlessly run their simulation or data analyses in distributed systems. In this project, we aim to provide empirical data to demonstrate on … Read More

Pegasus and LIGO
with No Comments

Early this month, the Pegasus team was very excited to hear about LIGO’s incredible discovery: the first detection of gravitational waves from colliding black holes. Since then, LIGO and Pegasus have been featured in several media channels. Below, we summarize some of these publications. Additionally, we provide the link to … Read More
