Chapter 5

On factory Instant Ignition, IUX will install workstation systems with optimized default

kernel parameter settings as long as the system has at least 64MB of RAM. The new

defaults are optimized for general performance and are tailored appropriately for a

32-bit or 64-bit kernel. (The default parameter settings for each set are listed at the end

of this section.) The larger maxdsiz limit for 64-bit installations now allows users to take

advantage of the increased (approximately 3GB) process data space available with the

June 2001 release.

Also on factory Instant Ignition, IUX automatically configures the kernel with the

appropriate new CAE kernel parameter set:

• CAE/ME/General Eng. Workstation 64-bit Kernel, or

• CAE/ME/General Eng. Workstation 32-bit Kernel

Via SAM, you can apply tuned kernel parameter settings by selecting one of these new

sets:

• CAE/ME/General Eng. Workstation 64-bit Kernel

• CAE/ME/General Eng. Workstation 32-bit Kernel

• EE Engineering Workstation 64-bit Kernel

• EE Engineering Workstation 32-bit Kernel

The 64-bit versions of these parameter sets configure the kernel to use the increased

process data space. The CAE/ME/General Engineering Workstation sets are for general

workstation use, which includes running typical MDA applications. The EE Engineering

Workstation sets are for compute-intensive applications that do not perform large

amounts of disk I/O. Many EDA applications fall into this category. Be sure to select the

64-bit or 32-bit versions depending on the “bitness” of your installed kernel.
