CRAY XC40 Getting Started

Welcome to HWW System CRAY XC30 named HORNET

• The Cray Programming Environment User's Guide (PDF) is a good starting point.

This guide describes the software environment and tools used to develop, debug, and run applications on Cray XT, Cray XE, Cray XK, and Cray XC30 systems. It is intended as a general overview and introduction to the Cray system for new users and application programmers.

This 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.

• Using the Batch System

• Disk Storage and Environments using modules

• Howto login

• The Linux Documentation Project

Notice!

The frontend nodes are accessible as hornet-network01.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 !
