Abstract
In the Claytronics project, we have used Meld, a logic program-
ming language suitable for writing scalable and concise distributed
programs for ensembles. Meld allows declarative code to be com-
piled into distributed code that can be executed in thousands of
computing units. We are now using Meld to program more tradi-
tional algorithms that run on multicore machines. We made several
modifications to the core language, to the compiler and to the run-
time system to take advantage of the characteristics of the target
architecture. Our experimental results show that the new compiler
and runtime system are capable of exploiting implicit parallelism
