HKS strongly recommends configuring a virtual swap area instead of using real swap space. The reason is that a virtual swap area will increase total logical swap space without using disk space. However, under IRIX, the memory resources are not shared by the child and parent processes. Instead, the system must reserve an amount of swap space for the child process that is equal to the current address size of the parent process when the child process is initiated. Pre will fail.
Pre model can easily consume several hundred megabytes of swap space.
This is why a minimum of 1Gb of logical swap space is required. Configuring a virtual swap area will not consume additional disk space, which real swap space will. All Sun graphics boards support the XGL graph's driver. In addition, the Creator 3D board also supports OpenGL acceleration. The other Sun graphics boards will run with the OpenGL driver on, but will run in a compatibility mode, which is not recommended.
