Hello all,
I am new to gadget2.
I want to know that how many processors should I use?
Followings are details:
Number of particles= 1500^3 = 3,375,000,000
RAM per processor = 4GB

The formula
M1=ParallelFactor* (Ntot/Np) * (68 + TreeFactor*64)

I do not know the use of Np(number of processor).
How to use this formula. What is M1. Please tell in detail.
Please also tell me how to calculate total RAM required to run this
Thanks in advance.
