About Directories and Files
LSF is designed for networks where all hosts have shared file systems, and files have the
same names on all hosts.
LSF includes support for copying user data to the execution host before running a batch
job, and for copying results back after the job executes.
In networks where the file systems are not shared, this can be used to give remote jobs
access to local data.
Supported file systems
UNIX
On UNIX systems, LSF supports the following shared file systems:
◆ Network File System (NFS)
NFS file systems can be mounted permanently or on demand using
automount.
◆ Andrew File System (AFS)
◆ Distributed File System (DCE/DFS)
Windows
On Windows, directories containing LSF files can be shared among hosts from a
Windows server machine.
Non-shared directories and files
LSF is usually used in networks with shared file space. When shared file space is not
available, LSF can copy needed files to the execution host before running the job, and
copy result files back to the submission host after the job completes. See “Remote File
Access” on page 588 for more information.
Some networks do not share files between hosts. LSF can still be used on these
networks, with reduced fault tolerance. See “Using LSF with Non-Shared File Systems”
on page 587 for information about using LSF in a network without a shared file system.
