The DCL list covers many components of data centers. Understanding the balance between FLOPs, storage and archival capacity is an important aspect that is tracked by the list. Since a storage system (or tape library) can be integral part of a supercomputer and, for example, procured together, or it can be procured separately and be installed on the site serving multiple supercomputers, this aspect must be described further underneath the characteristics. This should be also reflected in an architectural picture covering the topology. The data can be aggregated and filtered in multiple ways.
The following list is outdated – it needs an update to the current flexible data model
Generally speaking, a metrics is defined by the measurement procedure and a unit 1).
Most metrics can be determined without measurement and describe hardware and software characteristics that should be well known to the site and vendor. A few metrics cover actually observed metadata and I/O performance, in this case the measurement procedure must be clear.
The following list of metrics includes a description about the metrics.
There are two types of storage supported: tape archive and shared storage, e.g., file systems / object storage.
Compared to other lists (TOP500, Green500) that have a clear measurement process, the rules for determining performance values for the HPSL are often relaxed due to the complexity of I/O benchmarks, However it must be clarified how the measurement has been conducted.
