The current trend to multicore architectures underscores the need of parallelism. While new languages and alternatives for supporting more efficiently these systems are proposed, MPI faces this new challenge. Therefore, up-to-date performance evaluations of current options for programming multicore systems are needed. This paper evaluates MPI performance against Unified Parallel C (UPC) and OpenMP on multicore architectures. From the analysis of the results, it can be concluded that MPI is generally the best choice on multicore systems with both shared and hybrid shared/distributed memory, as it takes the highest advantage of data locality, the key factor for performance in these systems. Regarding UPC, although it exploits efficiently the data layout in memory, it suffers from remote shared memory accesses, whereas OpenMP usually lacks efficient data locality support and is restricted to shared memory systems, which limits its scalability.

MuPC is a portable runtime system for Unified Parallel C (UPC). A modified version of the EDG C/C++ front end translates the user's UPC program into C and turns UPC-specific language features into calls to MuPC runtime functions. MuPC implements each UPC thread (process) as two Pthreads, one for the user program and private memory accesses, and the other for remote memory accesses. Remote memory is accessed by two-sided MPI message passing. MuPC performance features include a runtime software cache for remote accesses and low latency access to shared memory with affinity to the issuing thread. MuPC is a useful platform for experimenting with current and future UPC language features and investigating UPC performance. This paper describes the internal design of MuPC and compares its performance to several other available platforms.

“…On the other hand, unified parallel C (UPC) was designed with a parallel language for distributed-shared programming paradigm in mind that also enables applications to run on SM machines. There are many benchmark results in the literature that compare the performance of OpenMP and UPC [11,12,20] with respect to many type of applications [7,10,35] and different type of architectures [3,7,13,36]. Most of the benchmarks compare the scalability of OpenMP and UPC against MPI.…”

The convergence of the two widely used parallel programming paradigms, sharedmemory and distributed-shared-memory parallel programming models, into a unified parallel programming model is crucial for parallel computing to become the next mainstream programming paradigm. We study the design differences and the performance issues of two parallel programming models: a shared-memory programming model (OpenMP) and a distributed-shared programming model (BSP).The study was carried out by designing a compiler for translating BSP parallel programs to an OpenMP programming model called BSP2OMP. Analysis of the compiler outcome, and of the performance of the compiled programs, show that the two models are based on very similar underlying principles and mechanisms.
