Abstract
Communication using blocking receives is the commonly used mechanism in parallel programming today. Message driven execution
is an alternate mechanism which does not use receive style
statements at all. The message driven execution style promotes the
overlap of computation and communication. Programs written in this
style exhibit increased latency tolerance: their performance does
not degrade significantly with latency. It also induces
compositionality: multiple independently developed modules can be
combined correctly without loss of efficiency. However, as the flow
of control is not explicit in such programs, they are often
difficult to develop and debug. We present a coordination language
called Dagger to alleviate this problem. The language has been
implemented in the Charm parallel programming system, and runs
programs portably on a variety of parallel machines.
