Run Parallel Processes

Runs a specified command in parallel over multiple input sources, optimizing execution speed in high-load situations.

Terminal

<arguments_source> | xe -j <max-jobs> <command>

<arguments_source> | xe -j <max-jobs> <command>

#!/bin/bash

# Run Parallel Processes
{{arguments_source}} | xe -j {{max-jobs}} {{command}}

When To Use

During data processing tasks that can be parallelized to enhance throughput efficiency.

Pro Tip

Set the maximum jobs parameter based on CPU core availability to fully utilize system capabilities without oversaturation.

Command Builder

Tune the command before you copy it

Generated Command

<arguments_source> | xe -j <max-jobs> <command>

Anatomy of Output

Executed process on line 1 with ID 1234. Process ID

Indicates a unique ID for each executed process.

Completed 4 tasks, 2 failed. Execution Summary

Report on the number of completed and failed tasks.

Error: line 2 caused segmentation fault. Error Message

Specific error output indicating a problem with processing an input line.

Troubleshooting

bash: cannot fork: retry limit exceeded

Solution: Reduce the number of max-jobs or check system resources.

process_line.sh: No such file or directory

Solution: Ensure the command exists and is executable in the given path.

fork: resource temporarily unavailable

Solution: Decrease concurrent jobs or investigate system limits on processes.

Command Breakdown

<arguments_source>: arguments source; The value supplied for arguments source.
<max-jobs>: max jobs; The value supplied for max jobs.
<command>: command; The value supplied for command.
-j: Command Option; Tool-specific option used by this command invocation.
