[Mesa-users] memory usage net

[amber lauer]

Hey guys, I'm doing some tests to optimize a model to not go over a certain
memory usage, and referring to this thread:

I am using the rough equation that memory usage for the net scales as

(isos+5)*nz*(3*isos+24)

But doing a quick test on my own, I get the following results:

num isos   num zones  mem_calc  mem actual:
53             ~750           8mb             1.06gb
153           750             55mb            2.92gb
305           750             200mb         8.96gb

(now, I'm getting my memory usage numbers from top and multiplying the % by
my total)
and the last two columns don't seem to scale by a constant. I'm looking for
information on how to predict the overall usage of my model  to keep it
below a fixed limit, and though I'm happy to use brute force to achieve the
desired results, I'm wondering what I'm missing. What other factors go into
the memory usage? Thanks.
