LORA Support
Starting with vPars A.05.05, LORA is enabled on multi-cell Integrity systems. LORA support
provides the vPars processor core selection algorithms to enable CPU allocation based on memory
proximity to the partition. This enables vPar systems to produce better data transfer rate and
reduce time to access memory. Therefore, enhancing the performance significantly for vPars on
multi-cell Integrity systems. With LORA enabled, an administrator or a user can configure vPars
using the vparcreate command along with CPU by count, and Cell Local Memory (CLM).
Also, specifying the I/O card from the same cell as that of memory further enhances the system
performance. For more information on LORA, see http://docs.hp.com/en/14655/
ENW-LORA-TW.pdf. The following sections discuss how LORA guidelines are implemented
on vPars.
