Errors running Linpack - mpi

Question

I'm trying to run HPL Linpack on my personal laptop. I'm using CentOS 8 on a VM.
Allocated cores : 6
Memory : 12.5 gb
Nodes : 1
When I run with smaller values of N, its running fine, but when I try to maximise the CPU usage, with bigger values of N(trying to go upto 75-80% of usage), I'm getting different errors each time.
ERRORS - All errors popped up on separate runs.
