Usage Examples
Intel compilers are optimized to computer systems using processors that support Intel architectures. They are designed to minimize stalls and to produce code that executes in the fewest possible number of cycles. The Intel C++ Compiler supports three separate high-level techniques for optimizing the compiled program: interprocedural optimization (IPO), profile-guided optimization (PGO), and high-level optimizations (HLO). The Intel C++ compiler in the Parallel Studio XE products also supports tools, techniques and language extensions for adding and maintaining application parallelism on IA-32 and Intel 64 processors and enables compiling for Intel Xeon Phi processors and coprocessors.
- Profile-guided optimization refers to a mode of optimization where the compiler is able to access data from a sample run of the program across a representative input set. The data would indicate which areas of the program are executed more frequently, and which areas are executed less frequently. All optimizations benefit from profile-guided feedback because they are less reliant on heuristics when making compilation decisions.
- High-level optimizations are optimizations performed on a version of the program that more closely represents the source code. This includes loop interchange, loop fusion, loop unrolling, loop distribution, data prefetch, and more.
- Inter-procedural optimization applies typical compiler optimizations (such as constant propagation) but using a broader scope that may include multiple procedures, multiple files, or the entire program.
Intel's compiler has been criticized for applying, by default, floating-point optimizations not allowed by the C standard and that require special flags with other compilers such as gcc.

Compiler Use
Prerequisites
To invoke the compiler from the command line, first you need to load the module
[user@login01]$ module purge [user@login01]$ module load intel/compiler/64/2016
Using the Command Line
To invoke the compiler from the command line, use a command similar to the following:
use a command similar to the following:
- For C source files: icc my_source_file.c
- For C++ source files: icpc my_source_file.cpp
- For Fortran source file : ifort my_source.f17
Following successful compilation, the compiler creates an executable file (usually a.out if not specified in the command line) in the current directory.
