LAPACK (Linear Algebra PACKage) provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems.
A highly optimized implementation of LAPACK is available on all OSC clusters as part of the Intel Math Kernel Library (MKL). We recommend that you use MKL rather than building LAPACK for yourself. MKL is available to all OSC users.

See OSC's MKL software page for usage information. Note that there are lapack shared libraries on the clusters; however, these are old versions from the operating system and should generally not be used. You should modify your makefile or build script to link to the MKL libraries instead; a quick start for a crude approach is to merely load an mkl module and substitute the consequently defined environment variable $(MKL_LIBS) for -llapack.
