Why Scientific Workflows?

Scientific workflows are a flexible representation to declaratively express applications with data and control dependencies, and are mainstream in domains such as astronomy, physics, climate science, earthquake science, biology, and others. Learn more.

 

Our Vision

The SciTech research group aims to empower the scientific community by tightening the relations between the domain scientists and current computational resources. As a result, scientists can focus on their research questions, while our open-source tools provide the computational foundations to seamlessly run their experiments and analyses in local and distributed resources.

Automation

We provide tools to automate and advance scientific analyses from the scientist's desktop to clouds and world-class supercomputers. Learn more.

Reproducibility

We enable computational reproducible research via data provenance, and data and software preservation mechanisms. Learn more.

Big Data

Our tools automatically manage large volumes of data transfers between different computational resources and data repositories. Learn more.

极光加速官网

We provide tools to collect fine-grained performance data from experiments and the computational environment. Learn more.

Seminar: Scheduling and Memory Management for Large-Scale Applications: From Caches to Burst Buffers
by on with No Comments

Abstract: This talk explores scheduling problems in the context of large-scale applications from a memory perspective. We focus here on two very different levels of memory in the hierarchy: caches and burst buffers.With the recent advent of many-core architectures such as chip multiprocessors … 极光加速器安卓

For the past 3 years the SciTech research group (led by Dr. Ewa Deelman) has enabled research endeavors via two DARPA-funded projects: RACE and MINT. The RACE (Repository and Workflows for Accelerating Circuit Realization) project is part of the DARPA CRAFT … 极光加速官网

Seminar: Checkpointing Workflows for Fail-Stop Error
Seminar: Checkpointing Workflows for Fail-Stop Error
by on with No Comments

We consider the problem of orchestrating the execution of workflow applications structured as Directed Acyclic Graphs (DAGs) on parallel computing platforms that are subject to fail-stop failures. The objective is to minimize expected overall execution time, or makespan. A solution … Read More
