Introduction to NEC SX-Aurora TSUBASA vector platform

This two day training will introduce the SX-Aurora TSUBASA installation at HLRS. The architecture will be presented and compared to other architectures and SX-ACE, an introduction to programming of vector CPUs will be given and vectorization will be discussed on examples. Usage of the system at HLRS will be demonstrated. In addition, an introduction to ML/DL solutions using the NEC SX-Aurora TSUBASA cards will be given. Participants can apply for test accounts to test their own code on the SX-Aurora TSUBASA after the course.
