dgelsd on AMD processor

[jaewonj]

The dgelsd issue (http://software.intel.com/en-us/forums/showthread.php?t=61809) doesn't seem to be fully addressed.

I'm getting "MKL ERROR: Parameter 4 was incorrect on entry to DLASCL" when running dgelsd on AMD processor

Jaewon,

what MKL version are you using?

Gennady,

It was 10.2.5. Would it make a difference with 10.3?

Hi Jaewon,

I've reproduced the issue.It will be fixed in the next MKL 10.2 Update. This concerns MKL 10.3.b too, and will be fixed in MKL 10.3.0 as well.

Michael.
