Clusters and Cluster Profiles
6-15
This opens the Discover Clusters dialog box, where you select the location of your
clusters. As clusters are discovered, they populate a list for your selection:
If you already have a profile for any of the listed clusters, those profile names are
included in the list. If you want to create a new profile for one of the discovered clusters,
select the name of the cluster you want to use, and click Next. The subsequent dialog box
lets you choose if you want to set the new profile as your default.
Requirements for Cluster Discovery
Cluster discovery is supported only for MATLAB job schedulers (MJS), Microsoft
Windows HPC Server, and Amazon EC2 cloud clusters. The following requirements apply
to these clusters.
• MJS — MJS clusters support two different means of discovery:
• Multicast: The discover clusters functionality uses the multicast networking
protocol from the client to search for head nodes where an MJS is running. This
requires that the multicast networking protocol is enabled and working on the
network that connects the MJS head nodes (where the schedulers are running)
and the client machines. This form of discovery might be limited to the client
local subnet, and therefore not always able to discover an MJS elsewhere in your
network.
• DNS SRV: An alternative discovery technique is to search for clusters by DNS
service records.
The Domain Name System (DNS) is a standard for identifying host names with
IP addresses, either on the Internet or in a private network. Using DNS allows
