This is a quick start guide for LSF, a batch scheduler that allows users to run their jobs on Livermore Computing’s (LC) Sierra (link is external) (CORAL) high performance computing (HPC) clusters.
Slurm is a combined batch scheduler and resource manager that allows users to run their jobs on Livermore Computing’s (LC) high performance computing (HPC) clusters. This document describes the process for submitting and running jobs under the Slurm Workload Manager.
This page includes a table that helps determine what is needed to access classified (SCF), unclassified Collaboration Zone (OCF-CZ), and unclassified Restricted Zone (OCF-RZ) Livermore Computing (LC) systems.
At Lawrence Livermore National Laboratory and increasingly more places, very large displays are being used in theatres for scientific visualization. These displays contain thousands of pixels in both X and Y, which combine to total several million pixels. To utilize these displays, very large movies are created. These movies, which are greater than about 1 million pixels, may play back unevenly due to the inability to move them off disk fast enough to render at the optimal frame rate, usually 30 fps.
HTAR ("HPSS Tape Archiver") is an LC-designed TAR-like utility program that makes TAR-compatible archive (library) files but with High Performance Storage System (HPSS) support and enhanced archive-management features.
This manual provides a basic guide for generating output and transferring files on LC computers. It outlines naming and locating tips for local network printers and introduces local tools (such as LISTPQ) for discovering and taking advantage of LC's standardized print-queue names.
EZFILES helps you effectively manage your files and directories on Livermore Computing (LC) computers. EZFILES explains the hierarchical structure of directories and file systems on LC computers, the properties and limits of those directories, the role of the common home directory, and the default search paths.
Both TapeFIS and OWL (one-way link) FIS are available on the iSNSI network. iSNSI TapeFIS is bidirectional and requires Derivative Classifier (DC) intervention for file transfers from Pinot to the OCF. Login examples are provided below. OWL transfers are significantly faster but are unidirectional for transfers from CZ and RZ to the SCF.
Retrieve files on the SCF by using SFTP/SCP, FTP or Hopper to make a copy of a file from the transfer server to your local machine. Initiate the FTP client software, connect to fastfis.llnl.gov, and complete the authentication process (by specifying a user name and SCF password). After you have connected to to fastfis.llnl.gov, change to your FROM directory and list the file(s) in the directory.
