![]() Regarding threading errors, it helps detect data races (both heap and stack), deadlocks and thread and synch API errors. Regarding memory errors, it helps detect memory leaks, memory corruption, allocation/de-allocation of API mismatches and inconsistent memory API usage. Intel also offers a tool for memory and threading error detection called Intel Inspector XE. In addition to the VTune profiler, there is Intel Advisor that specializes in vectorization optimization, offload modeling, flow graph design and tools for threading design and prototyping. It can also be integrated into Visual Studio on Windows, or Eclipse on Linux). VTune can be used from a command line or through an included GUI on Linux or Windows. While the Intel compiler can generate a gprof compatible profiling output, Intel also provides a kernel level, system-wide statistical profiler called Intel VTune Profiler. Debugging is done on Windows using the Visual Studio debugger and, on Linux, using gdb. The flags to compile with debugging information are /Zi on Windows and -g on Linux. The Intel compiler provides debugging information that is standard for the common debuggers ( DWARF 2 on Linux, similar to gdb, and COFF for Windows). Uses profile information during each step of the compilation process May only be used after running a program that was previously compiled using prof_gen. It sets compiler options -O3, -no-prec-div, and -fp-model fast=2” Įnables SSE, SSE2, and SSE3 instruction set optimizations for non-Intel CPUs Ĭompile the program and instrument it for a profile generating run “This option improves the speed of your application. “Performs O2 optimizations and enables more aggressive loop transformations” This is the generally recommended optimization level” “Enables optimizations for speed and disables some optimizations that increase code size and affect speed” Documentation ĭocumentation can be found at the Intel Software Technical Documentation site. The Intel C++ Compiler Classic is available either as a standalone component or as part of the Intel oneAPI Base Toolkit. The Intel oneAPI DPC++/C++ Compiler is available either as a standalone component or as part of the Intel oneAPI Base Toolkit, Intel oneAPI HPC Toolkit, and Intel oneAPI IoT Toolkit.
