Parameter documentation

This parameter defines the size (in MB) of the address space that is provided for the memory class "extended memory" in a work process. This also defines the total maximum size of extended global memory and extended memory for a single user context. The value is only relevant on operating systems that implement extended memory with mapped files, that is, operating systems that map extended memory in the address space of the process (Microsoft Windows NT, Linux, AS/400). A targeted setting of the value is required to make optimal use of the limited address space on 32 bit platforms or on 64 bit platforms if an extremely large amount of extended global memory or extremely large user contexts are required. The size of the address space for a process under 32 bit Microsoft Windows NT is 2 GB. Rule of thumb Code + roll area + total (buffers) + em/address_space_MB <(><<)> 2GB Approximately: 100MB+ 10MB + ? + ?
