After aborting the master kernel during a parallel computation and if remote kernels do not respond, you can try to reset them and bring them back into a usable state.
ResetSlaves can be used after a parallel computation has been aborted with the menu command Kernel Abort Evaluation
For some remote kernel connections, notably for kernels started on remote machines using LinkLaunch
, there may be no way to interrupt them. If a remote evaluation takes too long or is in an infinite loop, you must terminate the remote kernel process using the appropriate operating system command.
