Multi-Core Application Performance Predictability
and Throughput
Under normal operating conditions an application
run time determines the throughput capacity of
systems.
But on multi-core processor systems applications
tend to interfere randomly with one another
causing an effective loss of capacity to sustain
performance level expectations.
Node-Level Capacity Management, as per Multi-Core
Optimizer, is designed to eliminate job
interference performance impacts and optimize
throughput.
