Abaqus and parallel computing

Abaqus and parallel computing

Abaqus and parallel computing

(OP)
I was told by my supplier of Abaqus software that Abaqus will benefit from parallel computing up to 64 cpu cores. More than 64 cores show little benefit in computing time and beyond 128 cpu cores total computing time actually increases.

I am uncertain as to what type of simulations my supplier was referring to. Would this be both for implicit and explicit fea? And also for modal analyses and multiple load cases?

Please help me out. I need some flesh on the frail skeleton of my report.

RE: Abaqus and parallel computing

Explicit scales much better than implicit, because there is no large stiffness matrix to assemble and invert. 128 cores will be much faster thn 64. Speedup could 1.8 or 1.9.

In implicit features like couplings, procedure and solving method influence the benefit of paralleliszation. Speedup is maybe only 1.5.
