Can you not use Parallel Cluster, rather than the Parallel Computing Service? Parallel Cluster is just EC2 autoscaling and some shared storage through CloudFormation/CDK and a command line interface. I don’t think there are any secret special services?

If you set up slurm elastic cloud in EC2 without LDAP, what is the recommended method for sync of the passwd/group files? Is this necessary to get openmpi jobs to run. I would swear I had this working last week without synced passwd on two nodes. But thinking about it now I'm not sure how this could have worked. My home directories are in an NFS mount, but the user accounts don't exist on the node AMI. I'm using ansible/packer to manage the AMI's. When I ran OpenHPC / Slurm on bare metal there was a sync process. This is my first AWS Slurm cluster rodeo. I can't use the Amazon Parallel Computing tools because we are forced to be in GovCloud. I started with "ClusterInTheCloud", but it's all 4 years old, and semi-broken out of the box. My manager had me ditch a lot of it (including LDAP). So I'm building out a fork that is getting heavily modded for our situation. An ORTE daemon has unexpectedly failed after launch and before communicating back to mpirun. This could be caused by a number of factors, including an inability to create a connection back to mpirun due to a lack of common network interfaces and/or no route found between them.
