POSTPONED: Hawk Porting and Optimization Workshop

Research & Science Enterprises & SME Optimization & Scalability
POSTPONED: Hawk Porting and Optimization Workshop

Overview

Note: On March 10, this course was rescheduled to March 30 - April 03, 2020.

On March 13: We try to provide this course as online event. Due to Corona virus, no face-to-face teaching is allowed at the University of Stuttgart until April 19.

On March 30: Postponed

We will provide further information soon to the registered participants.

In this workshop, users can port their applications to HLRS’ new supercomputer Hawk (AMD-based HPE Apollo system, installed in early 2020) while being assisted by HLRS, HPE and AMD staff. By means of this assistance, it's further possible to enhance the node-level performance as well as scaling of the codes. By doing so, users can raise the quantity and/or quality of their scientific findings while the costs (in terms of core hours) remain constant.

In order to achieve usable performance enhancements, it is important to discuss pros and cons of potential solutions. This, however, requires application as well as machine expertise. Hence, this workshop brings together our users (with their application expertise) and support staff (HLRS, HPE and AMD staff) with their machine expertise.

Target audience: Groups holding a compute time budget to be used on Hawk.

Agenda & Content

Supported by HLRS and HPE specialists, you will port your application to the new supercomputer system “Hawk”. Furthermore, it’s possible to enhance the performance of the code. In order to do so, you will analyze the runtime behavior of your code, locate bottlenecks, design and discuss potential solutions as well as implement them. All categories of bottlenecks (CPU, memory subsystem, communication and I/O) can be addressed, according to the requirements of the code.

First day:

13:45-14:00 Registration   
14:00-14:15 Introduction   
14:15-17:30 Porting and Optimizing of your own applications to/on Hawk

Second-forth day:

09:00-17:30 dto.

Last day:

09:00-13:00 dto.

Important: If you plan to join the workshop, we recommend

Prerequisites
Prerequisites
  • Your group holds a compute time budget to be used on Hawk.
  • Please set up a test case to be used. While doing so, please adhere to the following requirements:
    • number of cores:
      • In order to be representative, the test case should be in size comparable to your current and maybe future production runs.
      • In order to save valuable resources, it should however be as small as possible.
      • So take into account to reduce the simulated domain and keep the computational load per node constant ("weak down scaling"). Ideally, the test case should use about 64 nodes.
    •  wall time:
      • In order to allow for a productive as well as effective workflow, the wall time should be a few minutes only.
      • At the same time, it should cover all important parts of the code, including I/O.
      • So take into account to reduce the number of simulated time steps.
      • Please figure out the time-stepping loop in your code so that analyses can be focused on that part.
