MTBF and Serviceability
| Attribution | Failures | MTBF | UDT | Serviceability |
| Cray | 0 | ∞ | 00:00 | 100% |
| Site | 0 | ∞ | 00:00 | 100% |
| External | 0 | ∞ | 00:00 | 100% |
| Other | 0 | ∞ | 00:00 | 100% |
| Overall | 0 | ∞ | 00:00 | 100% |
- Note 1: Serviceability%= 100*(WCT-SDT-UDT)/(WCT-SDT)
- Note 2: MTBF (Mean Time Between Failures) is defined as 732/Number of failures.
2: Performance Statistics
Technology Provision
| Description | Value |
| Technology reliability | 100% |
| Technology throughput | 8784 hours |
| Capability job completion rate | 100% |
| Technology MTBF | ∞ |
Note: Technology throughput is calculated: 12*(732-UDT-SDT); 732 - annual average number of hours in a month
Note: MTBF is calculated as 732/number of failures
