[petsc-users] Recommended processors according to problem size for good scaling

[TAY wee-beng]

Hi,

Is there a recommended no. of unknowns for each processor for good 
scaling? Supposed I have 1 million unknowns (cells), how many processors 
should I use?

I remember reading that 50k unknowns per procs is a good choice. Is that 
true?

-- Thank you. Yours sincerely, TAY wee-beng
