Re: [gmx-users] essential dynamics mdrun with SD integrator yields segmentation fault

2009-12-21 Thread Carsten Kutzner
Hi Chris, the segfault was due to the fact that with the sd integrator the constraints have to be evaluated twice and in the second call there is no pointer to the velocities present. I have fixed that in the master and release-4-0- patches branches. The velocity correction is now only done when

Hello, In my hands, mdrun throws a segfault when passing the -ei flag to mdrun and utilizing the sd integrator. I'll admit that I have only tried this with a single system. Nevertheless, using -linacc vs. -linfix makes no difference, neither does moving to constraints=none or parallel
