Yes, especially for systems with many electrons, according to the performance improvement they boast here: http://software.intel.com/sites/products/collateral/hpc/mkl/mkl_indepth.pdf > Compared to our Opteron cluster (ifort 9.1 / mkl 9.0), the Xeons (ifort > 11.1 / mkl 10.2.1.017) save > 50% calculation time. Yes, for the same reason as above. regards -- Lorenzo Paulatto SISSA & DEMOCRITOS (Trieste) phone: +39 040 3787 511 skype: paulatz www: http://people.sissa.it/~paulatto/ *** save italian brains *** http://saveitalianbrains.wordpress.com/
