3. Memory Management Schemes

• The Memory Management Reference

• LJ: Memory Access Error Checkers

• Unify

  Unify is a library and run-time package that provides a distributed shared memory abstraction for multiple processes. Unify lets programmers to write distributed applications that cross machine boundaries. Unify programs share memory in chunks called segments. Programs call "get" to update get the latest copy of a segment or "put" to send a copy of the segment to interested processes. Event counts and synchronizers are used for synchronization.

• Magnetic Bubble Memory Information

• Hoard

  Hoard is a fast, scalable and memory-efficient allocator for multithreaded applications on multiprocessors. Hoard solves the heap contention problem caused when multiple threads simultaneously call malloc() and free() (or new and delete).

• Multics Virtual Memory

• Belady's Anomaly

  FIFO handling of memory cache can result in the unexpected effect of performance actually declining when the amount of memory increases. Windows NT reportedly (but unverifiably) suffers from this problem.

• Dynamic Memory Management Research Group

• YAMD - Yet Another Malloc Debugger

  It's a package for finding dynamic allocation related bugs in C and C++ .

• Dmalloc - Debug Malloc Library

• pmap analyzes memory usage of processes on Linux

  This may be used to determine what's going on with X memory usage thus: pmap `pidof X`

  The result, on my system, was that X was mapping a total of 231MB, but of that, 169MB was being shared with other things (e.g. - shared libraries, the RAM on the graphics card, and so forth) such that the actual consumption associated with X itself was around 55MB, which is not particularly outrageous.
