Aurora Deep Dive Workshop
Programming for SX-Aurora TSUBASA
May, Thu 2 - Fr 3, 2019
11:30 am to about 2 pm
IT Center RWTH Aachen University
Seminar Room 3
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.
Date: Thursday 2nd – Friday 3rd May 2019.
Location: IT Center, RWTH Aachen University, Germany
Room: Seminar Room 3, Kopernikusstraße 6
Organizer: NEC and RWTH Aachen University

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 <firstname.lastname@example.org> for an individual test account.
The Dinner will be in the restaurant Palladion in the historical city of Aachen. Address:

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).
Most trains between Aachen and Düsseldorf stop at station Aachen West, which is 10 minutes walk away from the IT Center.
From the bus stop and the train station just walk up Seffenter Weg. The first building on the left side at the junction with Kopernikusstraße is the IT Center of RWTH Aachen University. The event will take place in the extension building located at Kopernikusstraße 6.
