We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello,

Can you please check the 4 possible reasons shown in the error ?

if node187 can resolve hostname of node188 to an IPv4 address and the correct interface. 
verify if passwordless ssh works from node 187 (run something like "ssh node188 whoami" should result in your username being shown)
also verify that a firewall is not blocking ports used by intel MPI

what is the scheduler on this cluster ? see if the cluster administrator requires use of something else other than ssh ?
