Here post your question

Dear Experts,
My job file is like below.

gmx convert-tpr -s prod6.tpr -extend 10000.00000 -o prod7.tpr

gmx mdrun -s prod7.tpr -cpi prod6.cpt -deffnm prod7 -lambdaout prod7.dat -nb gpu -v -noappend -update gpu

But from log file I find that

           Core t (s)   Wall t (s)        (%)
   Time:   177399.258   177399.332      100.0
                     2d01h16:39
             (ns/day)    (hour/ns)

Performance: 4.870 4.928
Finished mdrun on rank 0 Mon Mar 24 00:10:29 2025

It take 2 days to complete 10 ns run in gpu.

How I improve the performance?

Hallo :)
Can u describe ur laptop/pc hardware? In order to select some parameters while building and compiling gromacs.
N.B. Be ready to reinstall gromacs on ur device, but if uve only one gpu, im afraid theres nothing that can help u, except for some new hardware.
