Administering IBM Spectrum LSF Data Manager

The administrator of IBM Spectrum LSF Data Manager is an LSF administrator who performs tasks that are specific to LSF Data Manager.

Managing the dmd daemon
An LSF data manager host is an LSF server host that is configured to run the LSF data manager daemon. The dmd daemon communicates with the clusters it serves, and manages the transfer of data between source repository for data requirements and the execution environment of jobs that have data requirements.
Managing the staging area (cache)
A staging area (or data cache) is a managed file system on a data transfer (I/O) node or a mounted directory that is local to the cluster compute nodes that access it. The staging area stores input files that are to be staged in for job execution or job output files to be staged out to the source repository after the job finishes. Each staging area is managed by a single LSF data manager. Each cluster defines an LSF data manager and the staging area that it manages.
Managing data transfer
Configure and manage data transfer nodes and the queue that serves them. All data transfers are managed as LSF jobs. You can control both the number of concurrent transfers and the priority of transfers in the data transfer queue. For example, you can configure fair share between users in the data transfer queue.
Data specification files
A data specification file is a text file that is used for staging a large number of data requirement files at one time through LSF Data Manager. Each line in a data specification file specifies the name of a data tag or the path to a source file to be transferred to the staging area before a job is submitted and scheduled. The tag or path can point to a file or a directory.
Configuring IBM Spectrum LSF Data Manager to use the IBM Spectrum LSF multicluster capability
LSF Data Manager integrates with existing forwarding policies in the LSF multicluster capability to ensure that the availability of data requirements take precedence over availability of slots.
