HP UPC Version 3.3

HP Unified Parallel C (UPC), a parallel extension of the C programming language, supports both common types of multiprocessor systems: those with a shared global address space (such as SMP) and those with distributed memory. HP UPC Version 3.3 supports most HP Linux high-performance technical computing systems.

HP UPC provides a simple shared memory model for parallel programming, allowing data to be shared or distributed among multiple communicating processors. The language provides constructs that permit simple declaration of shared data, distribute shared data across threads, and synchronize access to shared data across threads. This model promises significantly easier coding of parallel applications and maximum performance across shared memory, distributed memory, and hybrid (DSM) systems. Development of the UPC language clearly illustrates the growing trend away from implicit towards explicit parallelism.

The HP UPC development environment includes the following components:

• The compiler driver program, upc, controlling the compilation and linking process.
• The compiler, upc_cc, run by the driver.
• The UPC Run-Time library, libupc, providing the interface between the compiler-generated code and the memory interconnect system. The library is also referred to as the UPC Run-Time System, or UPCRTS.
• The HP SHMEM library, libshmem.
• Supporting header files.
• Run-Time Environment components used on single-node SMP systems:
  • upcrun command, which launches UPC multiprocessor jobs on single-node SMP systems
  • upcrund, the daemon program that supports use of upcrun
  • Supporting scripts and documentation

The HP UPC documentation provides comprehensive reference and usage information for all product components. Online reference pages (man pages) are provided with the software. User documentation in HTML and PDF formats is provided on the HP UPC web site, http://www.hp.com/go/upc/.

• HP UPC Programmer's Guide - explains how to develop, run, and debug HP UPC programs and provides information about the UPC RTE (run-time environment).
• HP UPC Installation Guide
• The Release Notes provide important information about new features, compatibility with previous versions, and known restrictions.

HP UPC provides the following features:

Compiler Features

• The VAST optimizer package (from Crescent Bay Software) incorporated into the compiler, performing UPC-aware optimizations
• Extensive error checking and generation of diagnostics
• UPC-specific performance-related compiler options designed to allow tailoring of an application to the run time platform
• Ability to take advantage of same-node shared memory on clusters of SMP systems

Language Features

• Support for the UPC Version 1.2 Language Specification, including collective functions
• HP-specific performance-related pragmas
• HP language extensions, including timers, asynchronous data transfer functions, and SMP locality checking capabilities

Run-Time System Features

• Run-time diagnostics
• Extensive program consistency checks during initialization
• Run-time configuration capabilities, including
  • Caching
  • Heap configuration
  • Lock algorithm ("fair" or "greedy")
