I have two win 10 computers and I have enabled the built-in windows 10 OpenSSH Client and OpenSSH serve in both of them. I can use one of the computers to run programs on another computer. I have also set up the remote kernel through "kernel configuration options" and I can use the remote kernel from the local front-end.
Now I am trying to do parallel computing. I need to launch a remote kernel. According to the help documentation, I tried the command like this：
Needs["SubKernels`RemoteKernels`"] LaunchKernels[RemoteMachine[host, "ssh username@host \"D:\\Program Files\\Wolfram Research\\Mathematica\\11.3\\MathKernel -mathlink -linkmode Connect `4` -linkname `2`\"", 1]]
When I run this command a blank CMD window was popped up. I waited for a while and nothing happened (strictly speaking a Wolfram kernel process was in high CPU usage). So I closed the CMD window, and some error messages appeared:
LaunchRemote::time: Operation Run timed out after 15.` seconds.
LinkObject::linkn: Argument LinkObject[email@example.com, firstname.lastname@example.org, 225, 10] in LinkConnectedQ[LinkObject[email@example.com, firstname.lastname@example.org, 225, 10]] has an invalid LinkObject number; the link may be closed.
I googled for a long time and didn't find a solution. Can anyone help me?
