Re: [Repast-interest] Extending Patch class in Repast HPC

[Kashif Z. <ka...@pe...>]

Hello John

I ran rumor model both in compiled form and when I compiled it using VS. It
running perfect. For zombie_model, even the compiled example (with given
props files) is giving the same access violation error.

So it can be concluded that there is some problem with parallelism in zombie
model when it is running on my system. I do not know what?

With Best Regards.

Kashif,

You should be able to run with the /np 4 switch even on a machine with only
two processors; the additional processes are run as separate threads. It
won't be as fast as on a machine with 4 independent processors, but it
should run.

That said, the proc.per.x and proc.per.y properties in the Zombies model
have to match the number of processes when they are multiplied, not added.
The properties indicate the number of processes in the 'x' and 'y'
directions in the model's space; 2 x 2 = 4, 2 x 4 = 8, etc., are valid, but
the last settings you say you used, proc.per.x = 1, proc.per.y = 1, /np 2
are not. 

I'll have to check on the error tomorrow. There is no actual error shown in
the text you sent. Could you re-send? Or you can wait until your cluster is
installed and try again then.

Best,
John

Hello John

My error remains there.

About number of processors, it seems to be reason. Unfortunately I only can
use my own system with 2 processors right now. With switch np = 4, the
following error is generated:

I also tried it with /np 2 changing the 'proc.per.x = 1' and 'proc.per.y =
1'. But it does not work.

Our cluster facility is getting ready; installation etc. As soon as I get it
running on that facility, I will let you know.

Thanks for consistent support.

Best Regards.
