Release calendar:
=== 6.5.30 - Aug 2006 ===
 * The IRIX 6.5.30 release included the following for Guaranteed-Rate
   I/O version 2 (GRIOv2):
   * An extension to the node-level bandwidth allocation, which now
     has two options:
     * The node receives at most (ceiling) the configured bandwidth
       (previous behavior)
     * The node receives at least (floor) the configured bandwidth
       (new)
 * The following changes for ggd2:
   * Clarification that the -m option sets per-volume minimum
     distributed bandwidth allocator (DBA)
   * The new -s option, which sets per-node minimum DBA
   * The new -u option, which specifies the DBA update interval

drive type for STK T1000A tape drives, which are supported with APD
release 2.12.

Savings Time in accordance with the amendments to the Uniform Time
Act.

improve the accuracy of the measurement of shared memory usage within
a job.

 * SGI Origin 3900 server
 * F - CXFS
   * A new rolling annual upgrade policy permits you to upgrade from
     6.5.n to the n+1 or n+4 release. This policy is effective with
     6.5.18f.
   * The time required to update and propagate the database across
     nodes in the cluster has been significantly decreased.
   * If you use I/O fencing and ipfilterd(1M) on a node, the

     node and the telnet(1) port on the switch.
   * The CXFS Manager graphical user interface (GUI) has added a new
     icon to represent client-only nodes.
   * Application programmers should be aware that XFS recently
     relaxed the requirement that direct I/O be aligned along
     filesystem block boundaries. As of IRIX 6.5.19f, direct I/O will
     also be accepted using 512-byte alignment. This change makes the
     use of direct I/O on a CXFS partition more consistent with that
     of other vendors requirements and thus makes the use of CXFS
     more transparent.

 * F - CXFS relocation disabled; CXFS recovery supported on standby
   nodes In 6.5.18f, CXFS relocation is disabled by default and CXFS
   recovery is supported only when using standby nodes.
 * Support added for UDF filesystems The IRIX 6.5.18 release includes
   read-only support for the UDF filesystems format typically used
   for DVDs and packet-written CD-RWs.
 * QLFC enhanced driver messages QLFC has been enhanced to improve
   its output message format for messages logged to the console and
   SYSLOG.
 * New hinv command support The hinv command with the -v option
   displays the PCI/PCI-X bus speed of QLogic fibrechannel adapters
 * Beginning with IRIX 6.5.18, a user is able to keep the interrupt
   and processing load generated by interval timers away from
   specific CPUs. This feature may reduce latency and jitter for
   real-time applications.
 * Job limits support clarified Job limit values (rlim_t) are 64-bit
   in both n32 and n64 binaries.
 * Enhancements to atcheckpoint() and atrestart() At checkpoint time
   and at restart time, registered functions are called in the same
   order as the first-in-first-out order of their registration with
   atcheckpoint() or atrestart(), respectively.

   or XML documents to be published directly into HTML (our delivery
   format). These same tools are available to you as part of the "SGI
   Book Building Tools" product; formerly the "IRIS InSight
   Professional Publisher".
 * The overall behavior of the NFS Version 3 client has been modified
   to improve mixed and heavy load performance.
 * Device drivers now have the capability to create kernel threads
   not associated with particular interrupts to act as daemons and do
   background processing.
 * Support for several new networking interface functions have been
   added. They provide node name and/or a service name translation in
   a protocol-independent manner to support both IPv4 and IPv6.
