Description

This class will be a central point of organization for our memory management efforts.

It will need to be able to

  • Determine the amount of memory available for both windows and linux
  • Determine the amount of memory used by Mantid data stores (primarily the analysis data service)
  • It will be used by the WorkspaceFactory to determine whether to issue a memory reduced version of an algorithm.
  • It may (later on) inform less recently used workspaces to save themselves to disk to reduce memory.

(In [1267]) re #189. MemoryManager class created as a singleton. At the moment it can return the total physical memory of the machine and the available physical memory in KB. Workspace.getMemorySize() function is implemented to give approximate memory usage of the workspace.
