Error with running GROMACS with SLURM

I am running into errors while submitting a job for a basic MD Simulation with HPC on SLURM. My sbatch script reads as follows:

P.S.- I am new to GROMACS, and the last line is throwing error. In fact that is the line that my university's HPC cluster has reccomended to run MD simulations.

The error thrown is as follows:

Back Off! I just backed up nvt.tpr to ./#nvt.tpr.29#

Ifallocating memory from different pthreads/OpenMP threads, pleaseconsider setting MV2_USE_ALIGNED_ALLOC=1 for improved performance. UseMV2_USE_THREAD_WARNING=0 to suppress this error message.

Please can y'all help me with the same.
