Signature of LU factorisation and Armadillo

Ferrazzano__Vincenzo — Sun, 03 May 2020 17:40:42 GMT

In our project we use Armadillo and IntelMKL extensively, and Armadillo expects the LAPACK signature to be conformant to the ones on netlib.

Similar to what happened with a previous release (https://software.intel.com/en-us/forums/intel-math-kernel-library/topic/816284), the latest version of intel MKL (2020.1.216) seems to introduce the LU factorisation ?getrf as NOTHROW methods. This breaks the compilation, which is fixed by declaring noexecpt the corresponding armadillo methods.

For those who might need it: https://gitlab.com/vincenzo.ferrazzano/armadillo-code/-/commits/fix/9.870_MKL_2020

Why are these methods, and it seems only these methods declared as NOTHROW?

Should we expect more of these signature changes in the future?

Lapack's functions don't

Lapack's functions don't handle exceptions. You may try to submit the feature request to consider these options in one of the future versions.
