Is a 50 Hour MTBI Possible?
ASCI Red Experience in 1999
Hardware MTBI - > 900 hours
System Software MTBI - > 40 hours
ASCI Red has over 9000 processors
~4 hours Preventive Maintenance is performed per week
Integrated full system monitoring capability
Almost all unscheduled interrupts occur as a result of OSF/1 failures
(We believe that the software MTBI would be much better if Intel had remained in the supercomputer business.)
