[gmx-users] Restart simulation from checkpoint file with fewer nodes

[Husen R]

thanks a lot for your fast response.

I have tried it, and it failed. I ask in this forum just to make sure.
However, there was something in my cluster that probably make it failed.
I'll handle it first and then retry to restart again.

Regards,

Husen
