[gmx-users] trap invalid opcode

[Michael Brunsteiner]

Hi 

running a gmx job on a newly set-up debian-buster, with intel i7-3820 CPU, and one Nvidia 1060 GTX-6Gb
architecture, the job dies without further notice, nothing in log file, nor in stdout/stderr ...however in /var/syslogi find exactly at the time when gromacs stops this message:

Jan 26 23:42:39 rcpepc00609 kernel: [319870.261302] traps: gmx[21360] trap invalid opcode ip:7f68a6ef9ce5 sp:7f68937fddb0 error:0 in libgromacs.so.3.5.0[7f68a6418000+13a4000]
this is gmx-2018.5 on `uname -a`
Linux rcpepc00609 4.19.0-1-amd64 #1 SMP Debian 4.19.12-1 (2018-12-22) x86_64 GNU/Linux
gromacs was compiled with:
CC=gcc-7 CXX=g++-7 cmake .. -DGMX_BUILD_OWN_FFTW=on -DGMX_GPU=on
nivida driver version is 410.78 and cuda toolkit version is 10.0.130

anybody seen this before or some idea whence this error comes?
thanks!!mic
