Disk cache—miss ratio analysis and design considerations
Alan J. Smith
Pages: 161-203
DOI: 10.1145/3959.3961
The current trend of computer system technology is toward CPUs with rapidly increasing processing power and toward disk drives of rapidly increasing density, but with disk performance increasing very slowly if at all. The implication of these...

Optimistic recovery in distributed systems
Rob Strom, Shaula Yemini
Pages: 204-226
DOI: 10.1145/3959.3962

Optimistic Recovery is a new technique supporting application-independent transparent recovery from processor failures in distributed systems. In optimistic recovery communication, computation and checkpointing proceed asynchronously....

Error bounds for performance prediction in queuing networks
Y. C. Tay, Rajan Suri
Pages: 227-254
DOI: 10.1145/3959.3960
Analytic models based on closed queuing networks (CQNS) are widely used for performance prediction in practical systems. In using such models, there is always a prediction error, that is, a difference between the predicted performance and the...
