Thread segment stacks

摘要

This paper presents enhanced memory management concepts and their implementation providing better support for multi threading. The virtual address space of the multi threaded process is dynamically partitioned by a dynamic set of cooperating managers. Special thoughts are given to detect and solve possible thread stack and heap over-flows and collisions. Both stacks and heaps associated with threads are organized non-contiguously with linear segments to fuly exploit possibly large virtual address spaces. Grucial for the efficiency of this approach are modifications of the compiler and parts of the runtime system. The proposed so-lutions are implemented an evaluated on the SUN Sparc V9 architecture.
