 Berkeley UPC - 2.6.0 portable, high-performance Unified Parallel C compiler (File Size: 37,5 M) Current Version: 2.6.0 Release Date: 2007-11-11 License: Freeware Price: Free (BSD open-source license) Broken Link? Newer Version? Tell us! Product Description: Unified Parallel C (UPC) is an extension of the C programming language designed for high performance computing on large-scale parallel machines. The language provides a uniform programming model for both shared and distributed memory hardware. The programmer is presented with a single shared, partitioned address space, where variables may be directly read and written by any processor, but each variable is physically associated with a single processor. UPC uses a Single Program Multiple Data (SPMD) model of computation in which the amount of parallelism is fixed at program startup time, typically with a single thread of execution per processor. In order to express parallelism, UPC extends ISO C 99 with the following constructs: * An explicitly parallel execution model * A shared address space * Synchronization primitives and a memory consistency model * Memory management primitives UPC combines the programmability advantages of the shared memory programming paradigm and the control over data layout and performance of the message passing programming paradigm. Berkeley UPC is a high-performance, portable and fully open-source implementation of the UPC language designed for large-scale multiprocessors, PC clusters, and clusters of shared memory multiprocessors. Berkeley UPC is the first UPC implementation available for Mac OS X, and delivers competetive performance for supercomputing applications on the largest OS X clusters in the world, yet also provides support for UPC code development on Mac OS X laptops and desktop workstations. What's new in this version: * Multiconf build manager is now enabled by default, providing easy access to multiple UPCR configs (eg debug and opt) from the upcc command line * lapi-conduit now uses RDMA support on LAPI/Federation systems, when available, to improve communication performance * Data movement collectives now use a scalable, high-performance implementation * Add upcc -extern-main flag for programs with main() in non-UPC code * Suppress harmless warnings caused by a gcc 4.2 optimizer bug * Document workarounds for a gcc 4.x optimizer bug that can affect the correctness of shared-local accesses in rare cases. Operating System Requirements: This product is designed to run on the following operating systems: * Mac OS X 10.5 Intel * Mac OS X 10.5 PPC * Mac OS X 10.4 Intel * Mac OS X 10.4 PPC * Mac OS X 10.3.9 * Mac OS X 10.3 Additional Requirements: * XCode installed Screenshots:
