There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

HPEC LogoGeorgia Tech’s School of Computational Science and Engineering (CSE) presented six technical papers at the twenty-second annual IEEE High Performance Extreme Computing (HPEC 2018) conference this week.
Of the papers presented, three won or placed in a group of HPEC conference challenges, also referred to as the GraphChallenge.
The GraphChallenge seeks to develop tests from diverse research communities and groundbreaking efforts such as the Graph500 and GraphAnalysis, both of which CSE Chair David Bader is a committee member.
Fast Triangle Counting Using Cilk by CSE Professor Ümit Çatalyürek and Ph.D. Student Abdurrahman Yasar, as well as researchers form Sandia National Laboratory, was one of four submissions to win the title of 2018 GraphChallenge champions.
"Triangle counting is a representative graph analysis algorithm with several applications and one of three benchmarks used in the IEEE HPEC GraphChallenge,” said Yasar. “This paper improves upon the work that is implemented in Kokkoskernels library, one of the fastest implementations for the triangle counting problem in last year’s GraphChallenge.”
“In addition to fast implementation, this work also provides a significantly improved analysis of the results, showing better agreement between theory and experiment,” Yasar said.
Of the three winning submissions, Fast and Adaptive List Intersections on the GPUplaced as a GraphChallenge Finalist Paper and Logarithmic Radix Binning and Vectorized Triangle Counting received an innovation award.
"HPEC GraphChallenge provides a standard set of key graph problems that the larger community can work on. One of the difficulties is achieving good parallel performance across a wide variety of datasets,” said CSE Ph.D. Student James Fox, lead investigator of the GraphChallenge finalist paper submission.
“This paper contributes an input-adaptive approach to load-balancing and improving the performance of list intersections, important in triangle counting and other applications that involve finding common neighbors."
The conference takes place Sept. 25 through 27 in Waltham, Massachusetts.
