Hi,
Whenever I try to run the calculations on more than 80 processors, I end up with the error
mpid: Cannot create shared memory segment of -2124070912 bytes
Can some help what could be the reason for this? Thanks

most definitely not a LAMMPS reason, since "mpid" is an internal MPI
process. the number -2124070912 is very close to 2GB, so it is likely some
signed vs. unsigned or 32-bit vs 64-bit wraparound error.
this has to be an issue with your local machine or rather its software
configuration/installation.
