Hello everyone,

I've been working on REEF3F for 1-2 weeks and I've encountered an error. I will share the screen shots here, I've made a reasearch about in forum. Some of the users also suffered the same issue.

When I started the tutorial simulation(s) ( Not all simulation give this error) I got these errors/warnings. But solver manage to start to computate the case and finishes the simulation and I can view it in Paraview. So it does not seem a problem but why this is happening, btw I have 6 processor? I have no idea. I will copy the texts here;

Thank you for your help,

Have a nice week.

Baran.

Error/Warning:

WARNING: Linux kernel CMA support was requested via the
btl_vader_single_copy_mechanism MCA variable, but CMA support is
not available due to restrictive ptrace settings.

The vader shared memory BTL will fall back on another single-copy
mechanism if one is available. This may result in lower performance.
