 Description = f''' 
- Usage: Change number with core numbers/threads to use. I am suggesting to use total number of cores(or threads) - 1
- Usage: For AMD CPUs or using Intel CPUs without hyperthreading: (Example CPU is intel here, 4 cores or 8 threads)
-        $ mpirun -np 4 gpawsolve.py <args>
- For using all threads provided by Intel Hyperthreading technology:
-        $ mpirun --use-hwthread-cpus -np 8 gpawsolve.py <args>
+ Usage: 
+ $ mpirun -np <corenumbers> gpawsolve.py <args>
