CRAY XC40 Getting Started
Welcome to HWW System CRAY XC40 named HAZELHEN
- The Cray Programming Environment User's Guide (PDF) is a good starting point and every user is advised to read at least chapters 1-4.
The User's Guide describes the software environment and tools used to develop, debug, and run applications on Cray XT, Cray XE, Cray XK, and Cray XC40 systems. It is intended as a general overview and introduction to the Cray system for new users and application programmers.
- The CLE User Application Placement Guide (PDF) should be used in conjunction and describes how to launch and execute applications using the Cray Linux Environment (CLE) with the Application Level Placement Scheduler (ALPS) and aprun command in considerably greater detail.

The frontend nodes are accessible as hazelhen.hww.hlrs.de and are intended as single point of access to the entire cluster. Here you can set your environment, move your data, edit and compile your programs and create batch scripts. Interactive usage like run your program which leads to a high load is NOT allowed on the frontend/login node.
The compute nodes for running parallel jobs are only available through the Batch system !
