"""XBLAS is a reference implementation for extra precision BLAS.
|
|
|
|
XBLAS is a reference implementation for the dense and banded BLAS
|
|
routines, along with extended and mixed precision version. Extended
|
|
precision is only used internally; input and output arguments remain
|
|
the same as in the existing BLAS. Extra precisions is implemented as
|
|
double-double (i.e., 128-bit total, 106-bit significand). Mixed
|
|
precision permits some input/output arguments of different types
|
|
(mixing real and complex) or precisions (mixing single and
|
|
double). This implementation is proof of concept, and no attempt was
|
|
made to optimize performance; performance should be as good as
|
|
straightforward but careful code written by hand."""
