tamubatch is an automatic batch job submission script on Ada and Terra that allows you to submit batch job files without batch parameters. tamubatch takes a job file of executable commands and directly adds parameters to the job file so the user does not have to enter parameters every time. The user can specify specific batch commands with the use of flags or they may use tamubatch's default batch parameters.
[ NetID@ ~]$ tamubatch -help OPTIONS: SUBMISSION FLAGS: --walltime | -W <0:00> Sets the walltime for the current job in format 0:00. Default is 30 minutes --GPU | -gpu selects the gpu node to run the current job. --cores | -n <n> Sets the total number of cores for the current job. Default is one Core --cores-per-node | -R <n> Sets the number of cores per compute node. Default is 1 core per node. --total-memory | -M <n>MB/G Sets the overall memory limit for the current job. Must specify MB or G Default is <2500MB on Ada, 2000MB on terra> * Number of cores. --project-account | -P <Account Number> Sets the account to charge for the current job. --extras | -x "<all other LSF/SLURM flags>" Extra batch submission features for Users. ALL OTHER FLAGS: --command | -command "<bash commands>" Intended for Rapid prototyping --download | -download Generates script for download. Will not submit a job if flag is called. --help | -h | -help Shows this message and exits.
The batch file is a regular text file with the commands needed to be executed by the cluster. These commands can be linux commands, cluster commands, etc. Below is an example of commands that could potentially be found in batch job files.
echo "Hello" ml ml purge cd /scratch/user/directory ./my_script
The following are examples of calls to tamubatch.
Example 1: default submission
[ NetID@ ~]$ tamubatch my_job_file
In the above example, tamubatch will identify the job file (my_job_file) and then submit the job to the cluster with default parameters. The default parameters are 1 core and 1 core per node. On Ada, the default amount of memory is 2500MB (2.5G). On Terra, the default amount of memory is 2000MB (2.0G).
Example 2: job submission with flags
[ NetID@ ~]$ tamubatch my_job_file -W 1:00 -n 20 -R 20 -M 50G
In the above example, tamubatch will set the wall time to one hour, the number of cores to 20, the number of cores per node to 20, and the total amount of memory for the job as 50G. tamubatch will then submit the job (my_job_file) directly to the cluster.
Example 3: job submission with GPU node and extra batch parameters
[ NetID@ ~]$ tamubatch my_job_file -gpu -W 5:00 -n 40 -R 20 -M 80G -x "-B -N -u firstname.lastname@example.org"
After setting the number of cores, the number of cores per node, and the memory in the example above, tamubatch will select the gpu node to run the current job (my_job_file) and then includes extra batch parameters within the submission. In this specific example, the user will be alerted through email when their batch job starts to run and when their batch job is complete.
Example 4: batch job with commands
[ NetID@ ~]$ tamubatch my_job_file -W 1:00 -n 20 -R 20 -M 50G -command "echo hello; cd /user/net-id/"
Tamubatch will insert the same batch parameters as Example 2. Tamubatch will then add the commands entered using the command flag to the end of the batch job file (my_job_file). It will then submit the job to the clusters.
