Questions tagged [remote-access]

For questions about accessing a kernel on a remote/different computer either directly from the front-end or as a slave kernel to a locally running master kernel.

As the front-end runs separately from the kernel, the running kernel does not have to reside on the same machine as the front-end. These remote kernels can be started in one of two ways:

  1. directly communicating with the front-end, or
  2. as a slave kernel communicating with a master kernel.

This enables the harnessing the power of multiple computers in your calculations.
