Release Notes

3. The Scyld ClusterWare e1000e Ethernet driver is upgraded to version 1.2.17. This driver derives from source found

at http://sourceforge.net/projects/e1000/ﬁles/. We recommend using this Scyld ClusterWare driver instead of the native

RHEL4-U8 driver (version 0.3.3.3-k6).

4. Introduces beoweb, a web server that runs on a cluster’s master node to facilitate remote job submission and cluster

monitoring. Beoweb is an optional service (distributed as /sbin/chkconﬁg beoweb off) that must be enabled and started

prior to use.

5. Introduces POD Tools, which contains a command-line interface called POD Shell (podsh), that can be installed on

Scyld and non-Scyld systems. POD Shell interfaces with the new beoweb service to provide for remote job submission

and monitoring. See the User’s Guide for details.

6. Introduces python-scyld, which is derived from Open Source Python version 2.6.5, and pylons-scyld, both of which

provide a foundation framework for beoweb and POD Tools.

7. Introduces net-snmp-scyld. The Open Source net-snmp project includes various SNMP (Simple Network Management

Protocol) tools: an extensible agent, an SNMP library, tools for requesting or setting information from SNMP agents,

tools for generating and handling SNMP traps, a version of the netstat command which uses SNMP, and a Tk/Perl MIB

browser. This package also contains the snmpd and snmptrapd daemons and documentation. The new net-snmp-scyld

package is net-snmp with Scyld MIB module extensions built into the daemon. The Scyld MIB module implements Scyld

ClusterWare node monitoring of CPU, memory, and disk usages; the enabling/disabling of memory and disk usage traps;

and getting/setting trap thresholds. See the Administrator’s Guide for details.

8. Enhances the beostatus command to support remote master node monitoring (utilizing beoweb on the remote node) and

various options to ﬁlter the displayed information. See man beostatus and the Administrator’s Guide and User’s Guide

for details.

9. Improves the performance of beonss kickback name resolution from compute nodes.

10. Fixes a rare failure to PXEboot nodes that employ the igb Gigabit Ethernet driver.

11. Fixes the Scyld ClusterWare Ganglia "proc_run" graph that showed an incorrect and excessively large number of run-

ning processes.

12. openmpi-scyld is upgraded to version 1.5. This release restructures the locations of the compiler-speciﬁc libraries,

binaries, and manpages, and changes the contents of the environment modules. Existing applications that were built

against version 1.4.3 or earlier must be rebuilt against this new version.

13. TORQUE is upgraded to version 2.5.3.

14. Taskmaster version 5.4.1 is now available (under a separate license).

New in Scyld ClusterWare 4.8.1 Update - Scyld Release 481g0008

1. The base kernel is upgraded to 2.6.9-89.29.1 (481g0005). See https://rhn.redhat.com/errata/RHSA-2010-0676.html for

details.

2. OpenMPI is upgraded to version 1.4.3.

3. Fixes a problem that rarely exhibited itself as a waitpid() failure in programs executing in /etc/beowulf/init.d/

scripts during node bootup.

4. Enhances beoserv DHCP to better handle non-Scyld non-Linux compute nodes that request a DNS IP address.
