The Globus MDS resource information service — an LDAP-backed description of what a cluster has.
IANA assigns 2135 to the Grid Resource Information Server, registered by Steve Tuecke of the Globus project. GRIS is the resource-level half of the Globus Monitoring and Discovery Service: an LDAP-speaking daemon on a compute resource that publishes what the site has — CPUs, memory, queues, software — which site-level index servers then aggregate for job schedulers. It appears on grid clusters next to the GRAM gatekeeper on 2119. The Globus Toolkit MDS stack is retired, so anything still answering here is old software.
Expose with care
Read-only by design, but it advertises a detailed inventory of your compute hosts and runs on unmaintained code. Publish it only to the grid peers that need it.
