Changes to Fonts, PostScript® Viewing, and PDF Viewing Tools
Several of the fonts have been updated in this release, and as a result, customers may notice a change in some of the filenames used in the font directories. You may also see some minor changes to the fonts' appearance on the display. Applications that use fonts through the standard mechanisms in X11 should continue to operate correctly. Applications that directly access those font files in the DPS directory, however, may find that the file has been superseded and no longer exists in that location. Developers are encouraged to use the standard X11 mechanisms for accessing fonts to avoid this problem. The tools acroread (Adobe® Acrobat® Reader®). xpsview, and showps have been replaced with the more recent open source tools gsview and xpdf, which are built on top of the Ghostscript® package. These tools can be found on the Applications CD in this release. Customers who made use of the old tools should ensure that they install the new ones by selecting the images for gsview, xpdf, and Ghostscript from the Applications CD. The old tools will no longer be available, and will be replaced with wrapper scripts.
The wrappers for acroread and xpsview/showps will invoke the new xpdf or gsview commands respectively, but the wrapper scripts will pass all parameters verbatim, and will not attempt any translation. Thus, if an option changes or is not available for the new tool, customers may encounter an error if they use that option with the old command name from inside a script, for instance. Filesystems Changes to CXFS™ As of IRIX® 6.5.22, the IRIX® CXFS™ software is distributed on a separately orderable CD.
IRIX 6.5.23 provides the following new features for CXFS:
- Support for both relocation and recovery to a standby (idle) server.
- Relocation is disabled by default.
- Support for a cluster of up to 64 nodes.
- The ability to define a reset method for a given node to one of the following:
- Power cycle, to turn power off and on
- Reset, to simulate the pressing of the reset button on the frontof the machine
- NMI, to perform a nonmaskable interrupt
- You can define this method using either the cmgr command or the GUI. You can manually perform a powercycle or an NMI with the cmgr command.
- For information on these features, see CXFS Administration Guide for SGI InfiniteStorage.
SGI® Infinite Network Bandwidth SGI Infinite Network Bandwidth aggregates a number of physical network interfaces into a single virtual interface that is able to spread data evenly across all the physical interfaces in a stripe set. This allows multiple packets to be sent and received in parallel. This greatly increases the available bandwidth to the virtual interface. Dual-port Gigabit Ethernet board support
The IRIX 6.5.23 release supports the dual-port Gigabit Ethernet board. It is available in two formats:
- dual-port Fiber-Optic Gigabit Ethernet board
- dual-port Copper Gigabit Ethernet board
Barriers and Spinlocks IRIX 6.5.23 provides support for POSIX 1003.1j pthread barriers and spinlocks. Barriers provide a method of synchronizing multiple threads. Spinlocks are fast locking primitives that are operated on entirely in user space.
IPv6 support for the rtmon command added In IRIX 6.5.23, the rtmon-client and rtmond daemon support IPv6. rtmond is the server process that collects system and user events and dispatches them to clients such as padc, IRIXview™, and rtmon-client.
Support for Embedded Support Partner 3.0 For the IRIX 6.5.23 release, the Embedded Support Partner (ESP) has been upgraded to version 3.0, the same version of Embedded Support Partner deployed on SGI's Altix™ Family of Servers and Superclusters. The ESP2.0 event manager component has been decoupled and generalized to allow for more flexible system group management. An ESP3.0 System Group Manager (SGM) supports both ESP2.0 and ESP3.0 clients (Linux® or MIPS®). All existing ESP2.0 data will automatically be converted for use by ESP3.0.
Changes to Support Mode Status
The following workstations, graphics and scalable server systems have transitioned to retired support mode for the IRIX 6.5.23 release. IRIX 6.5.23 and beyond do not support installation on these systems.
