Release Notes

/usr/bin/htpasswd /etc/httpd/scyld-imf/htpasswd-users admin

To use Scyld IMF, point your Web browser at the URL http://MasterNode/scyld-imf, where MasterNode is the name or

IP address of the master node, whereupon you are prompted for a valid username (i.e., admin) and password (which was

initialized as described above). See the Administrator’s Guide for more details.

Optionally enable Ganglia monitoring tool

To enable the Ganglia cluster monitoring tool,

/sbin/chkconfig beostat on

/sbin/chkconfig xinetd on

/sbin/chkconfig httpd on

/sbin/chkconfig gmetad on

then either reboot the master node, which automatically restarts these three system services; or without rebooting, manually

restart xinetd, and start the remaining services that are not already running:

/sbin/service xinetd restart

/sbin/service httpd start

/sbin/service gmetad start

See the Administrator’s Guide for more details.

Optionally enable beoweb service

To enable the beoweb service that facilitates remote job submission and cluster monitoring (e.g., used by POD Tools):

/sbin/chkconfig beoweb on

then either reboot the master node, which automatically starts beoweb; or without rebooting, manually start beoweb:

/sbin/service beoweb start

See the Administrator’s Guide for more details.

Optionally enable NFS locking

If you wish to use cluster-wide NFS locking, then you must enable locking on the master node and on the compute nodes.

First ensure that NFS locking is enabled and running on the master:

/sbin/chkconfig nfslock on

/sbin/service nfslock start

Then for each NFS mount point for which you need the locking functionality, you must edit /etc/beowulf/fstab (or the

appropriate node-speciﬁc /etc/beowulf/fstab.N ﬁle(s)) to remove the default option nolock. See the Administrator’s

Guide for more details.
