A system monitors application-level performance metrics associated with a high-performance computing (HPC) application and resource-level performance metrics associated with resources provisioned for the HPC application. The system accesses an HPC deployment map representing placement and interconnection of the resources provisioned for the HPC application, and analyzes the application-level performance metrics, resource-level performance metrics, and the HPC deployment map to determine one or more recommended actions to improve the application-level and resource-level performance metrics. The system then executes at least one of the one or more recommended actions.

Dynamically composable data-in-place system

A storage system receives an initial failure rate of a storage device based on manufacturer specifications and determining a first erasure coding configuration to meet minimum reliability metrics. Data is encoded in the storage device using the first configuration. Operational data is then collected to monitor failures, and a second failure rate is determined if deviations from the initial rate exceed a predetermined threshold. Based on the updated failure rate and reliability metrics, a second erasure coding configuration, different from the first erasure coding configuration, is determined. The system then re-encodes data using the second configuration.

Anti-fragile storage systems

A file system stores data in a hierarchical storage system comprising a plurality of levels of storage units. If an indication of failure of a storage unit at a lower level is received, the storage system indicates a storage unit at the higher level as failed. The storage system initiates reconstruction of data at the storage unit at the higher level based on redundant data stored other storage units at the higher level. If the number of failed storage units at the higher level exceeds a threshold value, the storage system indicates that the storage unit at the higher level is available. The storage system initiates reconstruction of data at the storage unit at the lower level using redundant data stored in other storage units at the lower level. The storage system may perform data reconstruction at the higher level and lower level concurrently.
