[ruby-core:70244] Re: Force ruby to allocate a new heap page

>Could you explain what do you want to make?


We are using a C library (BOP, link here)
<http://roclocality.org/2015/05/17/rubybop-introduction/> that implements
OpenMP-like directives, using processes instead of threads to guarantee
correctness. BOP uses forks to achieve this, so at a point (at the start of
forks) we have different tasks with the exact same address space. Because
of how the library is implemented, these tasks cannot modify to the same
virtual address. Thus, we want the tasks to allocate a new heap page using
our custom memory allocator (which replaces libc malloc calls in ruby). To
force this new heap page allocation, we want to use the method in the last
message, as we are trying to minimize the changes to ruby itself. I hope
this is a bit more clear. I am trying to not go too much into the whole BOP
library in itself, for the sake of simplicity. If you're curious/interested
you can read the blog post (linked above) and/or the papers attached in
there. Thanks again!
