2 Intel® Math Kernel Library User’s GuideTable 2-1Threading modelLinking modelMPI usedWhat you need to know before you get started (continued)Select among the following options how you are going to thread your application:• Your application is already threaded• You may want to use the Intel® threading capability, that is, Legacy OpenMP*run-time library (libguide) or Compatibility OpenMP* run-time library(libiomp), or a threading capability provided by a third-party compiler• You do not want to thread your application.Reason. By default, the OpenMP* software sets the number of threads that IntelMKL uses. If you need a different number, you have to set it yourself using one ofthe available mechanisms. For more information, and especially, how to avoidconflicts in the threaded execution environment, see Using Intel® MKL Parallelism.Additionally, the compiler that you use to thread your application determines whichthreading library you should link with your application (see Linking Examples),Decide which linking model is appropriate for linking your application with Intel MKLlibraries:• Static• DynamicReason. For information on the benefits of each linking model, link commandsyntax and examples, link libraries as well as on other linking topics, like how tosave disk space by creating a custom dynamic library, see Linking Your Applicationwith Intel® Math Kernel Library.Reason: To link your application with ScaLAPACK and/or Cluster FFT, the librariescorresponding to your particular MPI should be included in the link line (see Workingwith Intel® Math Kernel Library Cluster Software).2-4
Intel® Math Kernel LibraryStructure 3The chapter discusses the structure of the Intel® Math Kernel Library (Intel® MKL) and, inparticular, the structure of the Intel MKL directory after installation at different levels ofdetail as well as the library versions and parts.Starting with version 10.0, Intel MKL employs the layered model (see Layered ModelConcept for details), which is a drastic design change aimed to streamline the librarystructure, reduce its size, and add usage flexibility.High-level Directory StructureTable 3-1 shows a high-level directory structure of Intel MKL after installation.Table 3-1High-level directory structureDirectory/doc/man/man3/examples/include/interfaces/blas95/interfaces/lapack95CommentMain directory; by default"/opt/intel/mkl/10.0.xxx",where xxx is the Intel MKL package number,for example, "/opt/intel/mkl/10.0.039"Documentation directoryContains man pages for Intel MKL functionsA source and data for examplesContains INCLUDE files for the library routines as well asfor test and example programsContains Fortran 90 wrappers for BLAS and a makefileto build the libraryContains Fortran 90 wrappers for LAPACK and amakefile to build the library3-1
