running opensees in Neeshub

[zishendemi]

Hi,

I tried to run a time history analysis of a large model of opensees model in Opensees Lab NEEShub. But it turns out that it took almost as much time as it did on the desktop in my office ( around 4 hr). Why is that?

Is running opensees in NEEShub parallel processing at all?

Thanks!

there are a number of possible reasons:
1) your computer is newish and is as fast as the ones on the hub which are a few years old now.
2) other people are also using the hub, as a consequence you are sharing the resources with others and your job is
getting swapped in and out as the operating system switches beween jobs

as for the parallel, it depends on how big the model is.

Thanks for your reply,

My model is 3-D and has almost 3000 nodes. Is it applicable to parallel computing?

Thanks!

yes, with such a big model you can take the advantage of parallel computing.
