An updated set of installers for IMSL, 2011.0.024, is available at the Intel Registration Center alongside the compiler for updates 9, 10 and 11 for customers with licenses that include IMSL. This contains corrections for certain IMSL routines when the _HPC library set is used - these call Intel MKL internally. MKL made a change in Update 9 which exposed a bug in the IMSL code for routines LQERR, VLQERR and L2RRR where they would get wrong results or report an error. No other changes are included.
If you use the _HPC library set (you include 'link_fnl_static_hpc.h' or 'link_fnl_shared_hpc.h' to pull in the libraries), we recommend that you download and install the updated IMSL package.
Feel free to reply here if you have any questions about this.
