Hello. I have written a code using pdsytrd to tridiagonalize a matrix, and it has worked perfectly on one set of machines (i386 running linux), but when I compile and run it on a second set (i686-pc-linux-gnu), I encounter an error that produces NAN's (not-a-number). I've traced the problem down to occur during a call to pdlatrd, when it calls the PBLAS routdine pdgemv. Has anyone seen this happen or know what might be causing it? Thanks!

Did you try to run the TRD tests from SCALAPACK/TESTING directory with your i386 and i686 machines?
If yes, do you have the same error?
