Icc intel compiler manual

The compilers whose name start with the letter ‘i’ use the same optimization flags, and all compilers have manuals available: man icc man ifort man icpc man dpcpp. Intel also has a document that makes recommendations for optimization options. The dpcpp compiler is based on the LLVM compiler family and uses the flags described on that page.  · Select the two boxes for the Intel C++ integration: there will be one box for “Intel® C++ Compiler Documentation” and a second box for “Intel® C++ Compiler XE for Linux* OS”. NOTE: * The Intel features will not be visible if you have Group items by category set – unset this option to view the Intel features.  · I have just checked that ifort compiler supports quadruple precision (real*16) and keeps 35 digits while icc compiler with 'long double' supports only 20 digits which is actually not a quadruple precision. The test was done at the x86_64 latitude laptop. What is the reason of the problem and how to.

PM. Views. While there is a cilkplus branch of gcc, and some of that is merged into gcc , gcc cilkplus isn't ready for release. Nor does icc Cilk (tm) Plus offer competitive performance on other than a few selected applications.
