The Question is:
How can I see the available amount of P0 in my system? Do you have any
documents which describe how do I size it ?
The Answer is :
On OpenVMS Alpha V7 and later and with the default setting of the
system VIRTUALPAGECNT parameter, the maximim P0 address space is one
terabyte in size, with the aggregate P0 and P1 space -- P1 space
provides an additional one terabyte -- available for each specific
process limited by its specific pagefile quota setting.
The maximum P2 space is rather larger than one terabyte in size.
For details on OpenVMS Alpha memory management, please see the OpenVMS
Programming Concepts Manual, and specifically please see the section
on Addressing and Memory Management, and its chapters that provide an
Overview of Virtual Address Space, details on Support for 64-Bit
Addressing, and information on Memory Management with VLM Features.
