For example:
$ mpicc object1.o ... -pthread -o myapp.exe
4.7.1.5 Quadrics SHMEM
The Quadrics implementation of SHMEM runs on HP XC systems with Quadrics switches. SHMEM is a
collection of high-performance routines (that support a distributed-memory model) for data passing
between parallel executables.
To compile programs that use SHMEM, it is necessary to include the shmem.h file and to use the SHMEM
and Elan libraries. For example:
$ gcc -o shping shping.c -lshmem -lelan
4.7.1.6 MPI Library
The MPI library supports MPI 1.2 as described in the 1997 release of MPI: A Message Passing Interface
Standard. Users should note that the MPI specification describes the application programming interface,
but does not specify the contents of the MPI header files, mpi.h and mpif.h, that are included in the
source code. Therefore, an MPI application must be recompiled using the proper header files for the MPI
library to which it is to be linked.
Parallel applications that use MPI for communication must include the HP XC infrastructure libraries.
MPI applications must be built with mpicc, mpic++, mpif77, or mpif90 utilities.
When an MPI application is launched, the user environment, including any MPI environment variables
that have been set, is passed to the application.
MPI profiling support is included in the HP XC MPI library, so you do not need to link with a separate
library to access the PMPI_xxx() versions of the MPI routines.
The HP XC cluster comes with a modulefile for HP-MPI. The mpi modulefile is used to set up the necessary
environment to use HP-MPI, such as the values of the search paths for header and library files.
4.7.1.7 Intel Fortran and C/C++Compilers
You can use Intel Fortran compilers (Version 7.x and greater) on the HP XC cluster. However, the HP XC
cluster does not supply a copy of Intel compilers. Intel compilers must be obtained directly from the
vendor. See the Intel documentation for information about using these compilers.
4.7.1.8 PGI Fortran and C/C++ Compilers
You can use PGI Fortran 95, Fortran 77, and C/C++ compilers on the HP XC cluster. However, the HP XC
cluster does not supply a copy of PGI compilers. PGI compilers must be obtained directly from the vendor.
For information about using the PGI compilers, see the PGI documentation.
4.7.1.9 GNU C and C++ Compilers
You can use the GNU C and C++ compilers on the HP XC cluster. The HP XC cluster supplies copies of
the GNU C and C++ compilers.
4.7.1.10 Pathscale Compilers
You can use the Pathscale EKOPath Version 2.1 Compiler Suite on the CP4000 platform only. See the
following Web site for more information:
http://www.pathscale.com/ekopath.html .
4.7.1.11 GNU Parallel Make
The GNU parallel Make command is used whenever the make command is invoked. GNU parallel Make
provides the ability to do a parallel Make; however, all compiling takes place on the login node. Therefore,
whether a parallel make improves build time depends upon how many cores are on the login node and
the load on the login node.
