As of August 9th, IRIX 6.5.9 is releasing with all new systems shipping
from SGI worldwide manufacturing centers.
The IRIX 6.5.9 release contains updates for both the maintenance (6.5.9m)
and feature (6.5.9f) streams.
The general distribution process is through the online ordering system.
IRIX 6.5.9m and 6.5.9f images are also available for download off
Supportfolio.
The IRIX 6.5.9 maintenance path delivers approximately 110 bug fixes that
were customer reported. In addition to the bug fixes, the IRIX 6.5.9
maintenance path delivers several software enhancements and additional
installation improvements. These changes are also available in the
IRIX 6.5.9 feature path.
New Hardware support in IRIX 6.5.9
- Support for the SGI Origin® 3000 server series, including the SGI Origin® 3200,
SGI Origin® 3400, and SGI Origin® 3800 servers.
The SGI Origin® 3000 series servers are distributed shared memory (DSM)
systems that scale from 2 to 512 processors. In a DSM system, each compute
node (2 or 4 processors) has local memory that it shares with the other
compute nodes in the system.
- The SGI 3000 series servers are based on SGI NUMA (formerly ccNUMA), a
cache-coherent non-uniform memory access architecture, which ensures that
the caches of the processors contain valid data. For example, if a processor
alters the data in a cache location and another processor has a copy of that
data in its cache, the processor that holds the copy will be notified that
the memory location no longer contains valid data. SGI NUMA architecture
also supports varied access times for local and remote memory references.
- Support for the TVO digital video option board for Silicon Graphics®
Onyx2® systems.
Software Enhancements delivered by IRIX 6.5.9m
Software Enhancements Delivered by IRIX 6.5.9f
IRIX 6.5.9f contains all enhancements delivered in 6.5.9m
- Support for the Scheduled Transfer Protocol
(STP). STP is a lightweight network protocol that
is compliant with the ANSI Standard Revision 3.1
protocol suite that is designed to support
extremely high performance data movement. STP
uses Direct Memory Access (DMA) to read and write
data into user space from a network interface.
This lets high bandwidth devices based on
Gigabyte System NetworkTM (GSN) perform at
network speeds with minimum interrupt overhead.
For more information, see the GSN main page
or http://www.hippi.org. In 6.5.6, STP was
initially added to the IRIX feature stream with
minimal functionality.
- Support for disk quotas that can now be set by project ID. Disk quotas
let you limit the amount of space a user or project can occupy and the
number of files (inodes) that each user or project can own. You can
implement hard or soft limits; hard limits are enforced by the system
and soft limits only remind the user to decrease disk usage.
- Support for the waitjob feature, which includes the new functions
setwaitjobpid() and waitjob(). These functions let the batch schedulers
query job information following job termination. When a batch scheduler
launches a job, it calls setwaitjobpid() to tell the new job what pid is
waiting for information upon termination. When the job terminates, it
remains as a zombie until either the batch scheduler calls waitjob() to
retrieve the job's termination information or the waiting pid no longer
exists. The information returned includes the job start time, usage
information, and reason for termination.
