Applications that need to manage and process large scale graph data have become prominent in recent times. Graph processing has attracted significant attention from the high performance computing community due to the complexities involved with the processing and storage of large graphs. The High Performance Graph Data Management and Processing 2016 (HPGDMP16) workshop aims to provide a unified platform for discussing the latest state-of-the-art efforts conducted to address research issues related to high performance large graph management and processing. HPGDMP’16 will be held in conjunction with the International Conference for High Performance Computing, Networking, Storage and Analysis 2016 (SC16). HPGDMP16 will be held in cooperation with ACM SIGHPC. The workshop will take place in the Salt Lake City Convention Center, Salt Lake City, Utah. We invite researchers who work in graph data management and processing in high performance computing environments to submit their original papers. For more information, visit http://hpgdmp.bsc.es/
