HLRS Stuttgart

In order to increase the efficiency of our users' applications on Hazel Hen, HLRS and Cray offer this workshop to enhance the node-level performance as well as scaling of the codes utilized by participants. By doing so, users can raise the volume as well as quality of their scientific findings while the costs (in terms of core hours) remain constant.

Supported by HLRS and CRAY specialists, you will analyze the runtime behavior of your code, locate bottlenecks, develop and discuss potential solutions as well as implement them. All categories of bottlenecks (CPU, memory subsystem, communication and I/O) will be addressed, according to the respective requirements. Ideally, the above steps will be repeated multiple times in order to address several bottlenecks.

In order to achieve usable efficiency enhancements, it is important to discuss pros and cons of potential solutions. This, however, requires application as well as hardware expertise. Hence, this workshop brings together application and hardware specialists in the shape of users and machine experts.
