Welcome to the Scyld ClusterWare User’s Guide. This manual is for those who will use ClusterWare to run applications, so it presents the basics of ClusterWare parallel computing — what ClusterWare is, what you can do with it, and how you can use it. The manual covers the ClusterWare architecture and discusses the unique features of Scyld ClusterWare. It will show you how to navigate the ClusterWare environment, how to run programs, and how to monitor their performance.
Because this manual is for the user accessing a ClusterWare system that has already been configured, it does not cover how to install, configure, or administer your Scyld cluster. You should refer to other parts of the Scyld documentation set for additional information, specifically:
Visit the Penguin Computing Support Portal at https://www.penguincomputing.com/support/documentation to find the latest documentation.
If you are looking for information on how to administer your cluster, refer to the Administrator’s Guide.
If you plan to write programs to use on your Scyld cluster, refer to the Programmer’s Guide.
Also not covered is use of the Linux operating system, on which Scyld ClusterWare is based. Some of the basics are presented here, but if you have not used Linux or Unix before, a book or online resource will be helpful. Books by O’Reilly and Associates are good sources of information.
This manual will provide you with information about the basic functionality of the utilities needed to start being productive with Scyld ClusterWare.
