Managing clusters of geographically distributed high-performance computers

We present a software system for the management of geographically distributed highperformance computers. It consists of three components: 1. The Computing Center Software (CCS) is a vendor-independent resource management software for local HPC systems. It controls the mapping and scheduling of interactive and batch jobs on massively parallel systems; 2. The Resource and Service Description (RSD) is used by CCS for specifying and mapping hardware and software components of (meta-)computing environments. It has a graphical user interface, a textual representation and an object-oriented API; 3. The Service Coordination Layer (SCL) co-ordinates the co-operative use of resources in autonomous computing sites. It negotiates between the applications’ requirements and the available system services. Copyright  1999 John Wiley & Sons, Ltd.
