Niehorster: I actually considered that, but while recreating the functionality of Boost.Pool is pretty easy, given that Boost.Intrusive now exists, a generic pool allocation library is some effort. some things that come to mind is multiple allocation algorithms to meet different time complexity and memory overhead needs, pools that allow allocation of different-sized objects, maybe even a generic "allocation algorithm" library that is not limited to chunks of memory, but can be used for disk space and other arbitrary ranges, like allocating IDs.
I recently tried to use the std::allocator drop-in replacement from Boost.Pool in a massively multithreaded program running on a machine with a lot of cores. The result was very disappointing.
as is expected. you might want to look into using thread specific pools, that only synchronize when a new pool block is allocated.
could you please elaborate a bit on this? How would i do this with the std::allocator implemenation provided by Boost.Pool? KR, Frank
