Subject: Re: [Help-glpk] GLPK re-endrant
The reentrancy issue could be obviated by
running GLPK instances in separate processes.
Nevertheless, most of the software around nowadays is meant to be run by
multi-cored CPUs. So, reentrancy actually seems to me something very close
to a requisite. The GLPK team will surely have to face it ASAP.
One can run multiple processes on multi-cored CPUs.
Shared memory isn't necessarily all that great a model,
but is difficult to avoid with threads.
Separate processes with explicit message-passing
can be a lot easier to wrap one's brain around.
The lack of a common address space makes it
hard for them to tromp on each others data.
