1 The C and FORTRAN compilers are required for dbaccess programming and the Patran Thermal module. Other modules and products do not require compilers. Note additional patch requirements in Table 5‑5.

2 Open GL libraries are required. Starbase is no longer supported.

HP-UX Patches
In addition to the basic operating system requirements listed in Table 5‑4, Patran requires the following software bundles and patches.Note that some patches may have special requirements of their own. These dependencies are documented by Hewlett-Packard. Patch numbers are also subject to change as new versions supersede existing patches frequently. Consult Hewlett-Packard to for additional information.

HP-UX Kernel Settings
The HP-UX System Administration Manager (SAM) is used to adjust kernel parameters. MSC.Software recommends the following changes to the default kernel settings:
 
Table 5‑6
Parameter
Description
Default
Recommended
maxdsiz
Max. Data Segment Size
64Mb
90% of swap
maxtsiz
Max. Text Segment Size
64Mb
64 Mb (no change)
maxssiz
Max. Stack Segment Size
8Mb
67108864 (64 Mb)
Patran requires a large block(> 64Mb) of virtual memory. The default maxdsiz is too low. Both the swap size and the maxdsiz parameter must be increased to make additional virtual memory available to Patran.
HP-UX Performance Tuning
There are several kernel parameter settings that may increase Patran performance on the HP-UX systems. MSC.Software provides the following suggestions.
 
Table 5‑7
Parameter
Setting
Default
fs_async
1
0
default_disk_ir
1
1 on HP700 class; 0 on HP800 Class
maxusers
100
32
Setting fs_async and default_disk_ir to 1 enables asynchronous disk writes and disk write caching. This enables faster I/O for Patran, since the application will not wait to verify that the write was completed.
There is a small risk associated with these settings. With fs_async and default_disk_ir set to 1, disk writes may not be complete should the system crash. This will not corrupt the Patran database. The reward (better database performance) outweighs the risk (lost data). These default parameters are set to support large network cluster applications, like online transaction processing, where data integrity is the primary concern at all times.
Maxusers
sets the maximum number of users. When you reduce the maximum number of users, HP-UX is able to free additional resources for individual processes such as Patran.
