UPC, or Unified Parallel C, is a parallel extension of ANSI C. UPC follows a distributed shared memory programming model aimed at leveraging the ease of programming of the shared memory paradigm, while enabling the exploitation of data locality. UPC incorporates constructs that allow placing data near the threads that manipulate them to minimize remote(More)
Co-array Fortran (CAF) and Unified Parallel C (UPC) are two emerging languages for single-program, multiple-data global address space programming. These languages boost programmer productivity by providing shared variables for inter-process communication instead of message passing. However, the performance of these emerging languages still has room for(More)
Parallel programming paradigms, over the past decade, have focused on how to harness the computational power of contemporary parallel machines. Ease of use and code development productivity, has been a secondary goal. Recently, however, there has been a growing interest in understanding the code development productivity issues and their implications for the(More)
UPC is an explicit parallel extension of ANSI C, which has been gaining rising attention from vendors and users. In this work, we consider the low-level monitoring and experimental performance evaluation of a new implementation of the UPC compiler on the SGI Origin family of NUMA architectures. These systems offer many opportunities for the high-performance(More)
The Distributed Shared Memory (DSM) model is designed to leverage the ease of programming of the shared memory paradigm, while enabling the high-performance by expressing locality as in the message-passing model. Experience, however, has shown that DSM programming languages, such as UPC, may be unable to deliver the expected high level of performance.(More)
