Parallel Utilities Library

• PUL is a set of libraries based on CHIMP (Common High-level Interface to Message Passing).
• EM library provides collective communication routines
• GF utility provides support for access to a common shared file for a group of processes.
• PF utility provides support for access to a file distributed over a number of disks. For efficiency, the distribution pattern of the file may be matched to the access patterns of the application.
• RD utility supports the parallel computations on regular, Cartesian grids. Used for solving PDEs. An operator stencil is used to determine inter-process communications.
• SM utility provides support for dynamic load balancing and data migration on irregular 2 and 3-D meshes.
• TF utility provides support for event parallelism using the task farm concept.
