Shadow editing: a distributed service for supercomputer access

The use of long-haul networks by the scientific community to access resources at supercomputing centers has created a need for high-level user services and tools to provide transparent and efficient access to remote resources. A way to provide a computational service for supercomputer access in a distributed environment is described. The issues involved in the design of such a service are discussed, and attention is focused on a remote job submission facility. A prototype implementation is also described
