[gmx-developers] how to extend a run using tpbconv?

[andrea spitaleri]

Hi then,
I see that now gromacs can read checkpoint file. Which is now the right procedure to extend a 
simulation using tpbconv?

1. tpbconv -s file.tpr -f file.cpt -extend 1000 -o new
or
1. tpbconv -s file.tpr -f file.trr -extend 1000 -o new

2. mdrun -s new
or
2. mdrun -s new -cpi file.cpt

Then, do I need to keep the same number of cpus of the previous run or I can change?

thanks in advance

Regards,

andrea
