This week we released version 3.3 of the SwiftRNG software kit. This update adds device cluster scalability and fail-over capabilities to the SwiftRNG software API. With this, it is possible to use two or more SwiftRNG devices to additively increase the random number generation speed. By doing so, the reliability of the cluster is increased. This new API feature seamlessly integrates multiple devices and uses them concurrently as a single stream of random data. The API will monitor the health of the cluster and will resize the cluster on-the-fly, allowing device swapping in real-time. This makes it possible to remove and add SwiftRNG devices in the middle of random number generation.
