HP UPC is a parallel extension of the C programming language, which runs on both common
types of multiprocessor systems: those with a common global address space (such as SMP) and
those with distributed memory. UPC provides a simple shared memory model for parallel
programming, allowing data to be shared or distributed among a number of communicating
processors. Constructs are provided in the language to 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 systems.

4.2 Compilers

You can use compilers acquired from other vendors on an HP XC system. For example, Intel
C/C++ and Fortran compilers for the 64-bit architecture and Portland Group C/C++ and Fortran
compilers on the CP4000 platform.

Intel, PGI, and Pathscale compilers are not supplied with the HP XC system.

You can use other compilers and libraries on the HP XC system as on any other system, provided
they contain single-core routines and have no dependencies on another message-passing system.

Table 4-1

displays the compiler commands for Standard Linux, Intel, and PGI compilers for the

C, C++, and Fortran languages.
