If the parallel engine is installed on a computer that
runs Microsoft Windows Server, Standard or
Enterprise edition, edit the boot.ini file to
remove the /3GB switch and, if necessary, add the /PAE switch.
Before you begin
Save a copy of the
boot.ini file before
you make any changes to the file.
About this task
By default, Windows reserves
2 GB of memory for the kernel and 2 GB of memory for user mode programs.
When the /3GB switch is specified in the
boot.ini file,
3 GB of memory is reserved for user mode programs, and the amount
of kernel memory is reduced by 1 GB. This setting results in an insufficient
amount of memory for the kernel. To resolve this problem, remove the
/3GB switch, if present, from
boot.ini file.
In
addition, on servers that have more than 4 GB of physical memory installed,
specify the /PAE switch in the boot.ini file.
The /PAE switch specifies physical address extensions that allow a
32-bit processor to access memory that is above the 4 GB limit.
