Georgia Tech professors and researchers from the College of Computing gathered this week in the historic Indian city of Hyderabad to present their latest findings at the leading conference on parallel computing, where they earned one of four “Best Paper” awards.

From May 25-29, the Institute of Electrical and Electronics Engineers (IEEE) held the 29th annual International Parallel and Distributed Processing Symposium (IPDPS) in India.

Georgia Tech’s Srinivas Aluru returned to his home city as the invited program chair, a role held last year by the School of Computational Science and Engineering Chair David A. Bader.

Researchers from around the world submitted nearly 500 papers for possible inclusion in the conference agenda. Of the 109 papers that reviewers accepted, Georgia Tech presented six, and one was selected as a “Best Paper.” Graduate student Kenneth Czechowski, and professors Le Song and Richard Vuduc are the Georgia Tech co-authors who received one of the four best paper awards.

The IPDPS conference brings together top international scientists and students to collaborate and delve into many aspects of parallel computing.  They share research and ideas driving the design and performance of leading-edge technology, and expand the set and complexity of problems that can be addressed.

In all, the IPDPS 2015 conference featured 19 workshops, paper presentations, tutorials, and commercial presentations and exhibits.
