If Charm++ is built on top of MPI, the sub-communicator is passed directly as an argument in the communication calls, thus dividing the set of processes and their communication in a manner that most MPI  ...  If Charm++ is not built on top of MPI, the RTS uses this information to find the set of processes on which the given Charm++ instance should be initialized.  ...  It is evident that enabling interoperation can bring the best of both worlds together for achieving good performance, high programmer productivity, and code reuse.  ...

A Comparative Study of Asynchronous Many-Tasking Runtimes: Cilk, Charm++, ParalleX and AM++ [article]

We also evaluate four mature implementations of these runtimes, namely: Intel Cilk++, Charm++ 6.5.1, AM++ and HPX, that embody the principles dictated by these models.  ...  Then, the execution model of each runtime, which acts as a bridge between the programming model and the underlying machine model, is compared and contrasted to that of the others.  ...  Oftentimes, high-level programming paradigms use low-level programming paradigms as their targets to offer the best of both worlds.  ...

Hence, the membership service is suitable for deployment in the communication layer of MPI runtime systems, and we have integrated an early version into LAM/MPI.  ...  Our protocol shows response times in the order of hundreds of microseconds and singledigit milliseconds for reconfiguration using MPI over BlueGene/L and TCP over Gigabit, respectively.  ...  Overall, our membership service for MPI tasks combines the best of both worlds, the scalability of a decentralized membership protocol and the performance of existing fault-tolerant mechanisms within high-performance  ...

This paper describes the design and implementation of Flex-MPI, an MPI library extension which can automatically monitor and predict the performance of applications, balance and redistribute the workload  ...  Extensive experiments show that Flex-MPI can improve the performance, parallel efficiency, and cost-efficiency of MPI programs with a minimal effort from the programmer.  ...  AMPI is built on top of CHARM++, in which virtualized MPI processes are managed as threads encapsulated into CHARM++ objects.  ...
