Configures the maximum number of concurrent daemon processes that can run simultaneously in daemon mode. This helps manage system resources when processing multiple images.

​
Syntax

OpenComicAI.setConcurrentDaemons(count?: number): void

​
Parameters

​
count
number
default:"3"
Maximum number of daemon processes to run concurrently. Must be a positive integer.

​
Returns

void - This method does not return a value.

​
Behavior

  • Limits the number of upscaling processes running at the same time
  • When the limit is reached, older idle daemons are closed automatically
  • Higher values allow more parallel processing but consume more memory
  • Lower values reduce memory usage but may slow down batch processing

​
Example

import OpenComicAI from '@opencomic/ai-bin';

// Allow up to 5 concurrent daemons
OpenComicAI.setConcurrentDaemons(5);

// Process multiple images (up to 5 will run in parallel)
const images = ['image1.jpg', 'image2.jpg', 'image3.jpg', /* ... */];

for (const image of images) {
  await OpenComicAI.upscale({
    input: image,
    output: `upscaled-${image}`,
    daemonMode: true
  });
}

​
Performance considerations

​
High concurrency (5-10 daemons)

  • Faster batch processing
  • Higher memory usage (1-2GB per daemon)
  • Best for systems with abundant RAM

​
Low concurrency (1-2 daemons)

  • Lower memory footprint
  • Sequential or limited parallel processing
  • Better for resource-constrained systems

​
Default (3 daemons)

  • Balanced approach
  • Good for most use cases
