Comment (by vbraun):
Replying to [comment:142 mmarco]:
> Is it possible to use some memory balooning technique?
Gap does that already. I've described some of the details here:
{{{
def set_gap_memory_pool_size(size_in_bytes):
"""
Set the desired gap memory pool size.
Subsequently started GAP/libGAP instances will use this as
default. Currently running instances are unchanged.
GAP will only reserve ``size_in_bytes`` address space. Unless you
actually start a big GAP computation, the memory will not be
used. However, corresponding swap space will be reserved so that
GAP will always be able to use the reserved address space if
needed. While nothing is actually written to disc as long as you
don't run a big GAP computation, the reserved swap space will not
be available for other processes.
...
