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 guide is intended to be used in conjunction with Workload Management and Application Placement for the Cray Linux Environment (S–2496), which describes the Application Level Placement Scheduler (ALPS) and aprun command in considerably greater detail.
- The next document Workload Management and Application Placement for the Cray Linux Environment (PDF) inherits some end-user-specific information formerly provided in Cray XT Programming Environment User's Guide. If users need to launch and execute applications using the Cray Linux Environment (CLE) and are looking for a reference, this document is a good start.
- Howto login
The frontend nodes are accessible as hazelhen.hww.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 !
