SC19 BOF on HPC Graph Toolkits and the GraphBLAS Forum 9th Workshop on Irregular Applications: Architectures and Algorithms https://hpc.pnl.gov/BOF/ November 20, 2019 5:15 - 6:45 PM Colorado Convention Center, Denver, CO Room 605

-------------------- Program --------------------

Government agencies, industry, and academia are demanding a new generation of tools to efficiently solve large scale analytics problems in a variety of business, scientific and national security applications. This BoF aims at gathering the community of people interested in frameworks and workflows for large scale graph analytics, surveying the current approaches, identifying new challenges and opportunities, and laying a path toward future interoperable infrastructures. As in previous editions, we will invite the GraphBLAS community to participate in a discussion of the current state and evolution of GraphBLAS, with the goal of developing requirements and recommendations for future tools.

Organizers: Antonino Tumeo (PNNL), Jose Moreira (IBM), Aydin Buluc (LBNL), Mahantesh Halappanavar (PNNL), Tim Mattson (Intel), John Feo (PNNL)
