Tuning the T4’s CPU to Optimize Workload Performance

A note from my archives [2012].  Starting with the Oracle VM Server for SPARC 2.1 patch release (147507-01), you can use dynamic CPU threading controls to optimize workload performance on SPARC T4 systems. These threading controls enable you to specify the number of hardware threads to be activated per core. CPU performance can be optimized for CPU-bound workloads by tuning CPU cores […]

Conforming to the OVM for SPARC Hard Partition Licensing

Reference: http://www.oracle.com/technetwork/server-storage/vm/ovm-sparc-hard-partitioning-1403135.pdf CPU Cores and CPU Threads The Oracle VM Server for SPARC software runs on Oracle’s SPARC T-Series servers, which use SPARC T-Series processors. The SPARC T-Series processors have multiple CPU cores, and each CPU core has multiple CPU threads. By default, domains that are created with the Oracle VM Server for SPARC software are configured with CPU threads. […]
