Linking Your Applic<strong>at</strong>ion with <strong>Intel</strong>® M<strong>at</strong>h Kernel Library 5st<strong>at</strong>ic linking of user code myprog.f, sequential version of sparse solver, <strong>and</strong>sequential <strong>Intel</strong> MKL supporting LP64 interface.For other linking examples, see the <strong>Intel</strong> MKL support website <strong>at</strong>http://www.intel.com/support/performancetools/libraries/mkl/.Linking with Interface LibrariesLinking with the Absoft compilersYou can use <strong>Intel</strong> MKL with the Absoft compilers on systems based on <strong>Intel</strong>® 64 or IA-32architecture. Table 5-2 explains which Interface layer library must be included in the linkline to link with the Absoft compilers.Table 5-2Interface layer library for linking with the Absoft compilersArchiectureProgrammingInterface St<strong>at</strong>ic Linking Dynamic LinkingIA-32 Does not m<strong>at</strong>ter libmkl_intel.a libmkl_intel.so<strong>Intel</strong>® 64 ILP64 libmkl_gf_ilp64.a libmkl_gf_ilp64.so<strong>Intel</strong>® 64 LP64 libmkl_gf_lp64.a libmkl_gf_lp64.soLinking with Threading LibrariesIn the past, only few compilers other than <strong>Intel</strong>® ones supported threading of the user'sapplic<strong>at</strong>ion. Starting with <strong>Intel</strong> MKL 10.0 timeframe, additional compilers will be offeringOpenMP* threading. If an applic<strong>at</strong>ion compiled with such a threading compiler usedOpenMP threading <strong>and</strong> called threaded parts of <strong>Intel</strong> MKL versions lower than 10.0, theremight be difficulties. They may arise because MKL is threaded using the <strong>Intel</strong>® compilers,<strong>and</strong> threading libraries from different compilers are not comp<strong>at</strong>ible. This can lead toperformance issues, <strong>and</strong> perhaps even failures when incomp<strong>at</strong>ible threading is used withinthe same applic<strong>at</strong>ion. Starting with <strong>Intel</strong> MKL 10.0, several solutions are available incertain cases. Those solutions are provided both from the Threading Layer <strong>and</strong> the suppliedrun-time libraries found in the Compiler Support RTL Layer.The Solution in Layers. With this release of <strong>Intel</strong> MKL, the library is structured as layers.One of those layers is a Threading Layer. Because of the internal structure of the library, allof the threading represents a small amount of code. This code is compiled by differentcompilers (such as a gnu compiler on Linux*) <strong>and</strong> the appropri<strong>at</strong>e layer linked in with thethreaded applic<strong>at</strong>ion.5-9
