abstract = {We examine the question of how to get maximum output
bandwidth from a "real" application running on many nodes of
a Paragon. We consider synchronization, flow control,
message passing and partition management, and the use of the
PARtools performance monitoring and visualization
environment to understand and thus optimize these
aspects.The application is a "digital VCR": each processor
has in memory several compressed video frames, and these are
to be decompressed, sent to the Hippi device, and output to
a framebuffer at the fastest possible rate. While the Hippi
processor is capable of 80 Mbyte/sec, the aggregate
bandwidth from the computational processors is 21
Mbyte/sec.In this communication-bound application, we find
it optimal to have the communication device (the Hippi
processor) to have control, with other processors acting as
servers; rather than the processors having distributed
control and the Hippi processor acting as server.},
