Example ICC flags

Enable OpenMP.

Specifies the memory model for the compiled binary object as 32-bit.'

Specifies the memory model for the compiled binary object as 64-bit.'

Enables OpenMP* offloading compilation for target pragmas. This option only applies to Intel(R) MIC Architecture and Intel(R) Graphics Technology. Enabled by default with -qopenmp. Use -qno-openmp-offload to disable.
Specify kind to specify the default device for target pragmas
host - allow target code to run on host system while still doing the outlining for offload
mic - specify Intel(R) MIC Architecture
gfx - specify Intel(R) Graphics Technology

Enables OpenMP support.

Enable Debug output. Generate an optimization report to stderr

Enable levels of prefetch insertion, where 0 disables. n may be 0 through 4 inclusive. Default is 2.

Defines the accuracy (precision) for math library functions

This option improves precision of square root implementations. It has a slight impact on speed.

Improve precision of FP divides (some speed impact)

Specifies whether streaming stores are generated always - enables generation of streaming stores under the assumption that the application is memory bound auto - compiler decides when streaming stores are used (DEFAULT) never - disables generation of streaming stores

Produce symbolic debug information in object file (implies -O0 when another optimization option is not explicitly set)

May generate Intel(R) Advanced Vector Extensions 2 (Intel(R) AVX2), Intel(R) AVX, SSE4.2, SSE4.1, SSSE3, SSE3, SSE2, and SSE instructions for Intel(R) processors. Optimizes for a future Intel processor.

May generate Intel(R) Advanced Vector Extensions 2 (Intel(R) AVX2), Intel(R) AVX, SSE4.2, SSE4.1, SSSE3, SSE3, SSE2, and SSE instructions for Intel(R) MICs. Optimizes for a future Intel processor.

Adds the directory for include files to the search path at compile time.

Adds the directory for include files to the search path at compile time.

Adds the library directory search path at link time

Enables support for Offload.

Enables support of AVX2.

Specify optimization level n:

• -O1 does only basic optimizations to reduce code size and execution time
• -O2 does additional options which do not involve space-speed trade-off
• -O3 does more optimization, adding function inlining, other interprocedural analysis, and others.

Specify rightmost column for fixed form sources

No Fortran main method exists, use C equivalent instead.

Link MKL (Intel Math Kernel Libraries).

Code for Xeon Phi (ManyCore) enabled, GPU specific code disabled.

Enables the use of nested SIMD statements for OpenMP.

Invoke the Intel C++ Compiler

Invoke the Intel C Compiler

Invoke the Intel Fortran Compiler

Link using FFTW 3.3.6 library for Linux. Description from FFTW:

FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST).
