Comment:
I disagree with this positive review.
- "everybody seems to agree that the combination in nonsensical" ->
Citation needed !
- "You either want a binary that runs on all reasonably old hardware for
distribution, or you want to specify the architecture in detail" -> i want
both, that is why local and global variables are made for !
- The fact that the cross-packages SAGE_FAT_BINARY variable takes
precedence over the atlas-specific variable SAGE_ATLAS_ARCH is not
addressed in #10508.
- Currently, if i want to tune atlas for a specific old architecture, and
at the same time tell other packages not to use too recent sets of
instructions (which is coherent), i simply can not. I still consider this
as a bug. It makes all the predefined atlas architectures settings
useless: if i want to specify one of them, i can not use SAGE_FAT_BINARY
for the other packages, which impossible for an old architecture.
