|Compress the file being transmitted.|
|If the destination file already exists, replace it.|
|-F number, --fanout=number|
|Specify the fanout of messages used for file transfer. Maximum value is currently eight.|
|-j jobID[.stepID], --jobid=jobID[.stepID]|
|Specify the job ID to use with optional step ID. If run inside an allocation this is unneeded as the job ID will read from the environment.|
|Preserves modification times, access times, and modes from the original file.|
|-s size, --size=size|
|Specify the block size used for file broadcast. The size can have a suffix of k or m for kilobytes or megabytes respectively (defaults to bytes). This size subject to rounding and range limits to maintain good performance. This value may need to be set on systems with very limited memory.|
|-t seconds, fB--timeout=seconds|
|Specify the message timeout in seconds. The default value is MessageTimeout as reported by "scontrol show config". Setting a higher value may be necessitated by relatively slow I/O performance on the compute node disks.|
|Provide detailed event logging through program execution.|
Print version information and exit.
Some sbcast options may be set via environment variables. These environment variables, along with their corresponding options, are listed below. (Note: Command line options will always override these settings.)
SBCAST_COMPRESS -C, --compress SBCAST_FANOUT -F number, fB--fanout=number SBCAST_FORCE -f, --force SBCAST_PRESERVE -p, --preserve SBCAST_SIZE -s size, --size=size SBCAST_TIMEOUT -t seconds, fB--timeout=seconds SLURM_CONF The location of the Slurm configuration file.
When using the Slurm db, users who have AdminLevels defined (Operator or Admin) and users who are account coordinators are given the authority to invoke sbcast on other users jobs.
Using a batch script, transmit local file my.prog to /tmp/my.proc on the local nodes and then execute it.
> cat my.job #!/bin/bash sbcast my.prog /tmp/my.prog srun /tmp/my.prog
> sbatch --nodes=8 my.job srun: jobid 12345 submitted
