Title:
AN IMPLEMENTATION FOR NONBLOCKING MEMORY ALLOCATION
Document Type and Number:
WIPO Patent Application WO2001061471
Kind Code:
A3
Abstract:
Methods and systems consistent with the present invention provide a memory access function that distributes its control among programs running in a data processing system and allows multiple threads in a program to access the memory access function virtually simultaneously. The function allocates and deallocates memory to requesting threads. The function receives memory requests from executing threads and processes those requests by performing an atomic update operation. The function is included in a program and does not require operating system access to satisfy a thread's memory request.
