# Scalable Memory Allocator

Both the debug and release versions of oneAPI Threading Building Blocks (oneTBB) consists of two dynamic shared libraries, one with general support and the other with a scalable memory allocator. The latter is distinguished by `malloc` in its name. For example, the release versions for Windows* OS are `tbb<version>.dll` and `tbbmalloc.dll` respectively. Applications may choose to use only the general library, or only the scalable memory allocator, or both. See Memory Allocation for more information on memory allocation.
