@rhl-
should I just remove OUTPUT_NAME?
actually, i know, i'll do that only if you ask to flatten
Jack Poulson
@poulson
whatever leads to consistent, non-redundant output names is fine by me
Ryan H. Lewis
@rhl-
ok, I have a decent way of doing this
check it out now
essentially when you don't flatten directories nothing changes
and when you flatten it does the rename
want to merge it? then the copr repo will rebuild :)

@rhl-
@poulson: ping?

@rhl-
@poulson: it appears that the code is hanging inside of LeastSquares :(
ive seen this before, with OpenBLAS. I think there might be a build problem there.
Jack Poulson
@poulson
I doubt that the hang is Elemental-specific
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
Ryan H. Lewis
@rhl-
@poulson: how would you diagnose that?
@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..
Ryan H. Lewis
@rhl-
@poulson: can you merge my PR?
Jack Poulson
@poulson
Let me take a quick look
Also:
I had added line notes to your PR
They seem to not be addressed yet
Ryan H. Lewis
@rhl-
Maybe I misunderstood, I thought I did.
@poulson: see, releases are necesary. the world runs on them. time to do it.
Jack Poulson
@poulson
Need to run D&C EVD and DVD at scale at least once before releasing
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
Ryan H. Lewis
@rhl-
sounds like we have a release candidate.
Ryan H. Lewis
@rhl-
@poulson: turned out the problem was due to File I/O, everything is working as expected now.
Ryan H. Lewis
@rhl-
@poulson: ping?
Jack Poulson
@poulson
Pong
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
Ryan H. Lewis
@rhl-
Is that a bulge chasing type thing?
Jack Poulson
@poulson
yes
Ryan H. Lewis
@rhl-
I actually wrote some code for that once
@poulson: lets set a date and release version number and then lets create a milestone in GitHub
Ryan H. Lewis
@rhl-
@poulson: found the code: https://github.com/rhl-/qr
this is not necessarily efficient
Ryan H. Lewis
@rhl-
I think its only a distributed hessenberg too
i think we never finished the actual bulge chasing
Jack Poulson
@poulson
do you mean it was a distributed reduction to Hessenberg form?
Ryan H. Lewis
@rhl-
yeah
Jack Poulson
@poulson
what kind of data distribution?
Ryan H. Lewis
@rhl-
each processor gets a block
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
