If you add the following (all one line) to $HOME/.ssh/known_hosts I *think* that should work until Ben gets things fixed properly: knl11,10.17.6.16 ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBJiMA1fojuMaSQLcB6ue7rPJrNjgf+y1sdHx0KUCrzp0KFkrofuXRmuFPt5VODnWx02JiG9ZsQRif+JTf+hyviI= -Paul On Mon, Feb 6, 2017 at 8:17 AM, Luo, Ye <[email protected]> wrote:

I also encountered this since the knl11 is added to the queue. Ben is investigating the problem. For the time being, I use the following trick to avoid the problematic node. qsub a job qstat -lf jobid see if knl11 is assigned to your job. If yes, qsub your job again. Because it takes time to release knl11, your second job will be dispatched to a good node. Ye

Hello,

I am trying to run on the KNLs on JLSE, but I keep getting the error:

'Host key verification failed.’

I’ve checked all my ssh keys in the accounts page (because I updated them recently) and everything looks ok.

Is there another key I’m missing?

Thanks, Taylor
