Can a CPU-aware application run faster with Sun Grid Engine 6.2 Update 5 than a dedicated environment?
No. For a CPU-aware application, each job before Update 5 runs slower than a dedicated environment. But a projects consist of thousands of jobs, that are distributed to hundreds and thousands of CPUs, so the performance in a cluster is spectacularly better no matter if a job runs a bit slower. Update 5 eliminated this last hurdle. Update 5, in addition to the distribution to many nodes, each individual CPU-aware job may run as fast as in a dedicated environment. The use of Topological Scheduling has resulted in dramatic performance increases when tested at leading EDA customers.
