the basic question is what are the memory requirements of that function.

@brianthelion - actually we just want to know what the memory requirements are. for example for a standard brain mesh size of about 2 hemi x (100k vertices + 100k...

@brianthelion - i'll try to get more specifics this weekend.

yes and no. i can replicate the error when i run it on it's own, but not when i'm memory profiling it. i have limited it to the zernicke function....

pong! sorry i have had no time to test this issue. unfortunately this will require me to carve out an hour or two and those have been a little scarce!...

ok - so here is the issue: https://github.com/binarybottle/mindboggle/blob/master/mindboggle/shapes/zernike/pipelines.py#L232 multiprocessing doesn't use shared memory and makes copies of every data bit that's passed through `map_async` which is used in the line...

@brianthelion - it's actually the same pattern that's used throughout that file. i just used one example to highlight it.
