HPC Clusters

The following is a list of possible issues you may encounter when using OpCenter in HPC Mode.

Where can I find the AMI ID and image snapshot ID for the region in which my OpCenter operates?

The OpCenter uses a custom virtual machine image (ami in AWS terminology) and a custom container image (called mm-hpc) to create HPC cluster nodes. Contact your MemVerge sales team to make the ami and container image available to your CSP account in your preferred region.

I am using OpenLDAP as the LDAP server, but it does not recognize the group semantics sent by the OpCenter.

The OpCenter uses the semantics of POSIX-compliant systems. The OpenLDAP schema uses different group semantics that are not compatible. Include the nis schema in your LDAP server configuration to enable POSIX-style semantics.
