libflame
Known Issues
---
The following is a list of known issues with libflame.
o It is not yet possible to create a matrix with arbitrary row and column
(ie: where both strides are non-unit). But we plan to add this functionality
soon.
o Due to limitations in the current level-3 interfaces, all blocked variants
implementing Hermitian rank-2k update (her2k) suffer from the inability to
compute the correct result when the alpha scalar parameter is complex and
has a non-zero imaginary component. (Note: this is difficult to fix.)
o The algorithm-by-blocks for incremental up-and-downdating via the UT
transform requires that the number of rows in C and D be equal. We will most
likely fix this as soon as someone complains.
o A parallel region cannot be used around the _solve() routine for either
FLASH_QR_UT_inc() or FLASH_CAQR_UT_inc(). This is due to the fact that
these routines use FLASH repartitioning. Enclosing this functionality
in a parallel region means that FLASH views are allocated and then freed
before threads are dispatched.
