A parallel processing device includes a parallel processing engine implemented by a processor. The parallel processing engine is configured to execute a shell script for each particular processing job in a queue of processing jobs to run. The shell script is configured to dynamically generate a configuration file for each particular processing job. The configuration file instructs a network of computing systems to run the particular processing job using a particular number of parallel partitions corresponding to a parallel partitions parameter associated with the particular job. The configuration file includes randomized scratch directories for computing nodes within the network of computing systems and a calculated container size for the particular processing job. Each processing job is run on the network of computing systems according to the dynamically-generated configuration file of the particular processing job.
