         'Split-C, A Practical Parallel Language 
             for Distributed Memory Machines' 

                 Dr. David E. Culler
         U.C. Berkeley, Computer Science Division

The traditional distinctions between Shared Memory, Message Passing,
and SIMD are disappearing as technology forces machine designs toward
systems based on state-of-the-art microprocessors with sizable local
memory and a fast network interface.  Split-C seeks to abstract this
emerging common structure while retaining its fundamental performance
characteristics, much as C does for modern uniprocessors.  Split-C
provides the programmer with an explicit global address space, while
retaining the ability to run highly-tuned sequential code on each
local portion.  It provides a rich set of global access operations to
allow communication to be optimized.  Within this framework, shared
memory, message passing, and data parallel programming can be freely
mixed as alternative programming styles.  I will present the Split-C
language and its CM-5 implementation based on Active Messages.
