2^nd Aurora Deep Dive Workshop

Programming for SX-Aurora TSUBASA

Nov, Thu 28th – Nov, Fr 29th, 2019

11:30 am to about 2 pm

Introduction

The NEC SX-Aurora TSUBASA is a new vector processor based accelerator for HPC workloads. Since this vector engine (VE) provides a very high memory bandwidth (1.2 TB/s), it is a very promising architecture for memory bound applications. The VE is provided as a PCIe card in a x86-64 server. Each VE is equipped with 8 cores. This workshop provides detailed information about the Aurora Architecture. Experts from NEC will present the programming environment and the different  execution models including hints for performance tuning. The attendees of the workshop have the opportunity to explore the system by working on provided hands-on or bringing their own code.

Bring Your Own Code

All attendees have the opportunity to bring their own code and get assistance from the NEC experts for code porting and performance tuning. If you want to bring your own code please keep in mind to prepare a small, but representative data set. We have 8 VE (8 cores and 48 GB memory each) available. Since we have to share the VEs with all attendees the data set should not use more than 8-16 MPI processes and less than 48 to 96 GB. Furthermore, the runtime should be about 10 minutes (or less). If you want to prepare your code or data in our environment before the workshop begins, please contact Tim Cramer <cramer@itc.rwth-aachen.de> for an individual test account.

Dinner

The Dinner on thursday 28th of november probably will be in the restaurant Palladion in the historical city of Aachen. Address:

Restaurant Palladion
Schmiedstraße 3
52062 Aachen

Registration

Please note: This is an invitation only event! If you recieved an invitation, please registerhere >>>until November 15th, 2019 November 1st, 2019 (extended)

Travel Information

Please make your own hotel reservation. You may find a list of hotels in Aachen on the web pages of Aachen Tourist Service.  We recommend that you try to book a room at the INNSIDE Aachen, Novotel Aachen City, Mercure am Graben or Aachen Best Western Regence hotels. These are nice hotels with reasonable prices within walking distance (20-30 minutes, see city map) from the IT Center through the old city of Aachen. An alternative is the IBIS Aachen Marschiertor hotel, located close to the main station, which is convenient if you are traveling by train and also prefer to commute to the IT Center by train (4 trains per hour, 2 stops).
