Runner::Slurm - Job Submission to Slurm
Runner::Slurm->new_with_options(infile => '/path/to/commands');
This module is a wrapper around submitting arbirtary bash commands to slurm.
It has two levels of management. The first is the main, and the second is controlled by Runner::Threads or Runner::MCE for the jobs.
It supports job dependencies. Put in the command 'wait' to tell slurm that some job or jobs depend on some other jobs completion. Put in the command 'newnode' to tell Runner::Slurm to submit the job to a new node.
The only necessary option is the --infile.
cmd1 cmd2 && cmd3 cmd4 \ --option cmd4 \ #Tell Runner::Slurm to put in some job dependencies. wait cmd5 #Tell Runner::Slurm to pass things off to a new node, but this job doesn't depend on the previous newnode cmd6
User options can be passed to the script with script --opt1 or in a configfile. It uses MooseX::SimpleConfig for the commands
Config file to pass to command line as --configfile /path/to/file. It should be a yaml or xml (untested) This is optional. Paramaters can be passed straight to the command line
--- infile: "/path/to/commands/testcommand.in" outdir: "path/to/testdir" module: - "R2" - "shared"
infile of commands separated by newline
cmd1 cmd2 --input --input \ --someotherinput wait #Wait tells slurm to make sure previous commands have exited with exit status 0. cmd3 ##very heavy job newnode #cmd3 is a very heavy job so lets start the next job on a new node
modules to load with slurm Should use the same names used in 'module load'
Example. R2 becomes 'module load R2'
Specify a job name, and jobs will be jobname_1, jobname_2, jobname_x
slurm item --cpus_per_task defaults to 8, which is probably fine
--commands_per_node defaults to 8, which is probably fine
#Should probably have something at some point that you can specify multiple partitions....
Specify the partition. Defaults to the partition that has the most nodes.
Defaults to the nodes on the defq queue
Bool value whether or not to submit to slurm. If you are looking to debug your files, or this script you will want to set this to zero. Don't submit to slurm with --nosubmit_to_slurm from the command line or $self->submit_to_slurm(0); within your code
actual template file
One is generated here for you, but you can always supply your own with --template_file /path/to/template
serial Option to run all jobs serially, one after the other, no parallelism The default is to use 4 procs
user running the script. Passed to slurm for mail information
Bool value to indicate whether or not to use threads. Default is uses processes
If using threads your perl must be compiled to use threads!
Bool value to indicate whether or not to use processes. Default is uses processes
You should not need to mess with any of these.
template object for writing slurm batch submission script
keep track of the number of commands - when we get to more than commands_per_node restart so we get submit to a new node.
Keep track of which node we are on
Keep track of how many batches we have submited to slurm
Node we are running on
Current command specified by infile
List of commands to submit to slurm
File of commands for mcerunner/parallelrunner Is cleared at the end of each slurm submission
File generated from slurm template
Array of arrays details slurmjob id. Index -1 is the most recent job submissisions, and there will be an index -2 if there are any job dependencies
Boolean value indicates any job dependencies
First sub called Calling system module load * does not work within a screen session!
Check to make sure the outdir exists. If it doesn't exist the entire path will be created
Get the nodes from sinfo if not supplied
If the nodelist is supplied partition must be supplied
Parse the file looking for the following conditions
lines ending in `\` wait nextnode
Batch commands in groups of $self->cpus_per_task, or smaller as wait and nextnode indicate
Get the node #may be removed but we'll try it out Process the batch Submit to slurm Take care of the counters
Create the slurm submission script from the slurm template Write out template, submission job, and infile for parallel runner
Submit jobs to slurm queue using sbatch.
This subroutine was just about 100% from the following perlmonks discussions. All that I did was add in some logging.
http://www.perlmonks.org/?node_id=151886 You can use the script at the top to test the runner. Just download it, make it executable, and put it in the infile as
perl command.pl 1 perl command.pl 2 #so on and so forth
