Batch Processing
Batch processing (also called batch jobs) is to combine a series of commands or programs together in sequence and execute them in batches in a batch file.In computers, batch processing allows computers to automatically complete repetitive tasks, such as printing documents, backing up data, running programs at scheduled times, etc.
In Java, batch processing can be implemented using the ProcessBuilder class in the Java language. The ProcessBuilder class allows a Java program to start and execute an external process and also redirect the output as an input stream for the Java program.Batch processing is very useful in Java backend development.It can automatically deploy and run applications to improve development efficiency.
On high-performance computing clusters (HPC), users typically submit batch jobs to predefined groups of compute nodes (called queues or partitions) that are managed by a resource management application. Some clusters employ a separate job scheduler that schedules batch jobs based on the availability of compute resources, user-specified job requirements, and usage policies set by the cluster administrator.
