The Question is:
We added an additional 4GB of memory to our system (before there were 256 MB,
the machine is a 4-way server). We increased the system parameters
accordingly to have access to at least 2 GB. The problem is that we cannot go
beyond 1 GB (using FORTRAN90 o
r C). So what to do to have access to the remaining memory? WSMAX in
modparams.dat for instance we set to WSMAX=4000000. In this file there is no
PHYS_MEMORY entry. Upon SHOW MEMORY the total memory (4 GB + 256 MB) is
recognized. Thanks in advance for
your answer.
The Answer is :
Assuming you have followed the steps in the FAQ (section MGMT11), you
will want to contact the Compaq Customer Support Center, as details
of process pagefault activity, working set sizes, and the numbers of
processes running will all be of some interest. (Access to physical
memory is generally entirely transparent, and entirely dependent on
system load.)
If you require more than one gigabyte (1 GB) of virtual memory within
specific a process (as differentiated from one gigabyte of physical
memory, or the amount of physical available to the process working
set based on the working set parameter), you will want to investigate
the use of 64-bit addressing as documented in the OpenVMS manual set.
