gc testbed information

gc gridx1

gc recommended software

You can register your hosts or sites with the Grid Canada testbed and look at information about hosts that are already registered.

Look at a dynamic list of the hosts registered with the GC testbed. (The list is generated with a PHP script that may take some time to return all the hostnames.)

Note that being registered does not imply that the host or site is in any other way accessible. Anyone who wants to use the resources of a host must first contact its administrator directly to be added to the access control list of that host.

Registering with the Grid Canada Testbed

We currently only support registration from hosts or sites which have Globus Toolkit 2.0 and above deployed, or more specifically, with the Globus Monitoring and Discovery Service 2.1 and above deployed. If you have other systems that you want to register, contact <gridmaster@gridcanada.ca> with suggestions of other platforms to support.

As well as following the instructions below, please send email to <gridmaster@gridcanada.ca> with contact information for the Globus administrator of the hosts or sites you register. In the email list the name of the hosts and sites, and give the email address (and as much other contact information as possible) of the administrator.

Under the Globus Toolkit 2.x

On the host whose GRIS or GIIS you want to register, as the Globus administrator add the lines


# register this server GRIS to the GC testbed GIIS

dn: Mds-Vo-Op-name=register, Mds-Vo-name=gc-testbed, o=grid

regtype: mdsreg2

reghn: giis.gridcanada.ca

regport: 2135

regperiod: 600

type: ldap

hn: <hostname>

port: 2135

rootdn: Mds-Vo-name=local, o=grid

ttl: 1200

timeout: 20

mode: cachedump

cachettl: 30

to the file

$GLOBUS_LOCATION/etc/grid-info-resource-register.conf

replacing <hostname> with the name of the host whose GRIS or GIIS you're modifying. If you are registering a GIIS, modify the line


rootdn: Mds-Vo-name=local, o=grid

to reflect the root DN of the GIIS. Under GT2.2 add the line


bindmethod: ANONYM-ONLY

to the lines above. Remember that for each registration entry that you are adding - such as this Grid Canada entry - there must be no empty lines between lines within an entry, but there must be at least one empty line between entries. Look at the structure of the existing grid-info-resource-register.conf if in doubt.

For the changes to take effect, you'll now have to stop


$GLOBUS_LOCATION/sbin/SXXgris stop

and restart


$GLOBUS_LOCATION/sbin/SXXgris start

the GRIS/GIIS server for the new configuration to take effect.

For more information about how to configure your GIIS or GRIS, visit the MDS pages.
