In the Claytronics project, we have used Meld, a logic programming language suitable for writing scalable and concise distributed programs for ensembles. Meld allows declarative code to be compiled into distributed code that can be executed in thousands of computing units. We are now using Meld to program more traditional algorithms that run on multicore machines. We made several modifications to the core language, to the compiler and to the runtime 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 in programs such as graph algorithms, neural networks and belief propagation algorithms.
