it might be worth checking that the ABI's all matched; hopefully there wasn't a mix-up between 64-bit int and 32-bit int versions
@poulson: I think I see the problem, I think you are right, it looks like the code is reading the matrix in wrong.
reading in row major..
Also:
I had added line notes to your PR
They seem to not be addressed yet
@poulson: see, releases are necesary. the world runs on them. time to do it.
Colleague at Julich claims something is not working in their driver since I made the switch, but it is a significant possibility that the problem is on their end
I would like to get a Henry/Walker/Dongarra style distributed Hessenberg QR impl' in before the official release so that dropping Scalapack as a default dependency does not sacrifice any serious functionality
This will help with the Debian package
I think I can have it working by tomorrow night if I scramble
@poulson: lets set a date and release version number and then lets create a milestone in GitHub
this is not necessarily efficient
i think we never finished the actual bulge chasing
its not much code.. and i'm sure you could improve upon it greatly
its been a long time since I thought about that
this was for something at Stanford
lexing's class or something
its not really high quality
you presumably have a distributed hessenberg already
yes, Elemental has distributed blocked algorithms for reducing to Hessenberg form
i didn't know about elemental then
the right paper to start on is http://www.netlib.org/utk/people/JackDongarra/PAPERS/140_2002_a-parallel-implementation-of-the-nonsymmetric-qr-algorithm.pdf
i was wondering if you have seen/considered cldoc ?
