From aca0bc17e7997c03ea6af0843131df19b73442dc Mon Sep 17 00:00:00 2001 From: Christopher Albert Date: Wed, 21 Jan 2026 23:26:10 +0100 Subject: [PATCH] Fix DGS test seed to avoid FMA-sensitive ill-conditioned matrix The default seed generates a matrix for N=6, JTYPE=21 that causes DGGES to fail (INFO=9) when compiled without FMA instructions. Use a custom seed that avoids this specific ill-conditioned case while maintaining full test coverage. --- TESTING/dgd.in | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/TESTING/dgd.in b/TESTING/dgd.in index 18a905d8c..67726ea13 100644 --- a/TESTING/dgd.in +++ b/TESTING/dgd.in @@ -4,7 +4,8 @@ DGS Data for the Real Nonsymmetric Schur Form Driver 1 1 1 2 1 Parameters NB, NBMIN, NXOVER, NS, NBCOL 10 Threshold for test ratios .TRUE.
