Intel Compilers and Libraries

Description

intel website  

Intel® Parallel Studio XE is a software development suite that helps boost application performance by taking advantage of the ever-increasing processor core count and vector register width available in Intel® Xeon® processors, Intel® Xeon Phi™ processors and coprocessors, and other compatible processors.

Note

The default intel version is 2016.0.109.

Required Modules

Serial

• intel

System Variables

• HPC_MKL_DIR - Intel MKL library installation directory
• HPC_MKL_LIB - Intel MKL library file directory
• HPC_MKL_INC - Intel MKL library include file directory

Compiling Serial Programs

Examples for compiling serial programs:

Source Langurage	Compiler	Command Example
C	icc	icc compiler_options example.c
C++	icpc	icpc compiler_options -o example.exe example.cxx
F77	ifort	ifort compiler_options -o example.exe example.f
F90	ifort	ifort compiler_options -o example.exe example.f90

For detailed information on compiler options, please refer to the compiler man pages or use "-help" command option, for example

icc -help
man icc

Compiling OpenMP Programs

For multi-threaded shared memory parallel applications using OpenMP threading paradigm, add "-openmp" to the compiler options. For example:

icc -openmp -O2 -o example.exe example.c
icpc -openmp -O2 -o example.exe example.cpp
fort -openmp -O2 -o example.exe example.f90

Please see Sample_SLURM_Scripts for example job scripts to run threaded or multi-processor jobs.

Compiling MPI Programs

For distributed parallel MPI programs, the MPI library supported on hipergator is OpenMPI. To use Intel compiler with OpenMPI, please load the modules:

 module load intel openmpi

Examples for compiling MPI programs:

Source Langurage	Compiler	Command Example
C	mpicc	epic -O2 -o MPI_example.exe MPI_example.c
C++	mpicxx	mpicxx -O2 -o MPI_example.exe MPI_example.cxx
F77	mpif77	mpif77 -O2 -o MPI_example.exe MPI_example.f
F90	mpif90	mpif90 -O2 -o MPI_example.exe MPI_example.f90
