Longstaff-Schwartz method doesn't need and shouldn't use full SVD.
LAPACK has thin version of SVD, but Eigen doesn't.

One possible option is to link to standard CBLAS/LAPACK interface. MKL
10.3 introduced C-API to LAPACK. The same interface can be built for
ATLAS, ACML or any other implementation that provides CBLAS/LAPACK
interface. A high level abstraction layer would separate users from
low level implementation. This way users would be able to link to
their favorite CBLAS/LAPACK implementation.
