Title:
dge
I experienced the same problem with the routine LAPACKE_dsyevd with a
6x6 matrix. I tried to check the eigenvalues with GNU/Octave and .. it
got stuck as well! The code was working a few days ago with Ubuntu 19.10
before the upgrade to 20.04.
The backtrace is:
#0 0x7599f70b in sched_yield
Here's the GDB stack trace:
#0 0x73aec70b in sched_yield () at
../sysdeps/unix/syscall-template.S:78
