VT GPGPU/DraftSurvey

EGI User Community GPGPU Survey

Overview

The use of General Purpose Graphics Processing Units (GPGPUs) or accelerator devices, such as Intel's Xeon Phi co-processor, over the past few years has resulted in a huge increase in their exploitation by all the major scientific disciplines. With three of the top 10 clusters in the current June 2012 Top500 supercomputers list using NVIDIA GPGPUs, we would expect the number of GPGPU deployments at grid resource centres to grow significantly over the next few years. Moreover

The purpose of this survey is to gauge how the users currently use, or intend to use, GPGPUs or other accelerated devices in Grid or hybrid Grid/Cloud environments, or whether they shall use grids for this purpose. In particular, we would like to determine if there is a specific need from the User Communities for a more tightly integrated GPGPU capability within the grid environment. In addition, we welcome further user comments and feedback on any other aspects.

All data collected from the survey feedback will be processed anonymously.
