Introduction » Memory Pool

Memory pool for efficient allocation.

The memory pool component vt::pool::Pool, accessed via vt::thePool() provides a highly efficient memory pool for fixed sized allocations in three sizes: small (vt::pool::memory_size_small), medium (vt::pool::memory_size_medium), and large (currently unimplemented).

All message allocation (on the send and receive side) is overloaded with new/delete overloads to allocate message memory through the vt memory pool. The pool implementation uses a non-thread-safe allocation policy (must be allocated/deallocated on the same thread) with fixed sized buckets. If the size exceeds the largest bucket, the memory pool will fall back on the standard allocator.
