fdps's Introduction

About

FDPS (https://github.com/FDPS/FDPS) ported and partially optimized version for SX-Aurora TSUBASA Vector Engine. This is based on FDPS version 7.1.

This is based on "VEOffload" function. On FDPS applications, main program is run on VH and user defined interaction functions are run on VE.

See HOWTO_SAMPLES about how to make/run samples and HOWTO_IMPLEMENTATION about how to implement FDPS applications with VEOffload.
