Toward Accelerated Unstructured Mesh Particle-in-Cell
TimeMonday, 18 November 20194:10pm - 4:30pm
DescriptionThe effective execution of unstructured mesh based particle-in-cell, PIC, simulations on
GPUs requires careful design and implementation choices to ensure performance
while maintaining productive programmability.
This paper overviews the developing PUMIPic library
that employs a set of mesh centric data structures and algorithms
upon which unstructured mesh PIC simulation codes can be developed.
Current performance results for component tests on up to 96 GPUs of the Summit system at
Oak Ridge National Laboratory are presented.
