K1.1-B System Architectures

various system-, hardware-, and I/O-architectures used for supercomputers, i.e. shared memory systems, distributed systems, and cluster systems
physical hardware; chassis/rack, computer system units, interconnect, power., compute node architecture with memory, local disk, and sockets
typical architecture of cluster systems consisting of nodes with different roles (e.g. so-called head, management, login, compute, interactive, visualization nodes, etc.)
Comprehend there are nodes with several functions
- Login or gateway nodes where you are on after logging into the cluster
- Compute nodes that are the workhorses of a cluster
- Admin or system nodes that work in the background necessary for the operation of the cluster, e.g. for running the batch service, or starting and shutting down compute nodes
- Disk nodes that provide global file systems, i.e. file systems that can be used on all other kinds of nodes
- Special nodes e.g. for data movement, visualization, or pre- and post-processing of large data sets
- Head nodes which can mean login or admin nodes used for management either by a user or an administrator
