The Math Kernel Library (MKL) patch will fix the Math Kernel Library used by LabVIEW Analysis VIs. Without this patch, Analysis VIs may crash LabVIEW on machines with 16 or more cores as noted by Corrective Action Request 357899. This may cause small changes to insignificant digits for the outputs of the VIs. This is strongly recommended for LabVIEW 2009, LabVIEW 2010, and LabVIEW 2011 on machines with 16 or more cores. For a machine with LabVIEW 2009 SP1 and 16 or more cores, consider additionally installing the LabVIEW 2009 SP1 f5 Patch.
