I need an order of magnitude higher stack size limit to run our climate
model
with chemistry. This model runs on various other platforms (e.g. Linux
PC
Clusters, Alpha workstations, Nec SX6), where we can either increase the
stack size limit (within sh) or where it is already sufficiently high
(SX6).
Thus, I wonder why this should not be possible on a Mac, which yields
with 1024 MB Memory and G4 1 GHz already a comparable performance
compared to a Linux PC Cluster or Alpha workstation (on one CPU).
What's about the option to recompile the kernel?

The current configuration (OS X 10.2.6, X11 Beta 3 - XFree86 4.2.1)
seems to allow only a decrease?
You can raise and lower the stack size at will, but there is a hard
limit of 65536 KB that you cannot exceed. Even a superuser can't
exceed that limit; it may require a kernel recompile to change.
Why do you need a stack larger than 64 MB, anyway?
