About performance.
So this builds are still not good? based on the earlier comment:
"""
Hm, I've tried /usr/lib/s390x-linux-gnu/z13/libatlas.so.3.10.3. The sgemm/dgemm
kernels from this library don't use any vector instructions, thus the
performance for dgemm is off by a factor of 2. Something must have gone wrong
in the build, although I couldn't determine the problem from the build log for
"3679 - 2019-03-15".
"""
Can you perchance provide a full build-log, of how you build the library
locally for z13 (without any debian/ubuntu packaging) and get the
exepcted performance? Such that i can dig into that build log to figure
out what i am doing wrong?
