errors with scalapack due to [cz]symv and [cz]syr interfaces

ajaypanyala opened this issue 5 months ago · 10 comments

Using BLIS to configure Reference LAPACK and ScaLAPACK, results in link errors (duplicate definitions) due to the [cz]symv and [cz]syr interfaces introduced in Commit 37ca4fd. ScaLAPACK defines them here

Answer 1 · 2024-06-18T03:24:52.000Z

I guess we need a configure flag to turn these off.

Answer 2 · 2024-06-18T22:05:18.000Z

Regardless of what we do, maybe LAPACK/ScaLAPACK need a configure flag to turn them off on their side.

Answer 3 · 2024-06-18T22:23:12.000Z

ScaLAPACK works fine with BLIS before Commit 37ca4fd. There doesn't seem like a way to turn those interfaces off in ScaLAPACK.

Answer 4 · 2024-06-18T23:17:05.000Z

My only concern is whether this should be an option specific to those operations or if it should be a generic "ScaLAPACK compat" option in case something else comes up.

@ajaypanyala is [cz]syr2 affected?

Answer 6 · 2024-06-18T23:32:24.000Z

Looks like it is.

Answer 7 · 2024-06-18T23:36:10.000Z

Atleast on my end, I do not see any issues with [cz]syr2

Answer 8 · 2024-06-18T23:38:02.000Z

It's because I didn't enable them in BLIS when I did [cz]syr and [cz]symv which was an oversight on my part. I've included all 3 in the fix.

@ajaypanyala please try the branch scalapack-compat and configure with the option --enable-scalapack-compat.

Using scalapack-compat branch with --enable-scalapack-compat worked. thanks!
