PEdriver, the software that enables OpenVMS Cluster communications
over a LAN, now provides Fast Path support. This new PEdriver feature
provides the following benefits:
Improves
SMP performance scalability.
Reduces the contention for
the SCS/IOLOCK8 spinlock. PEdriver uses a private port mainline
spinlock to synchronize its internal operation.
Allows PEdriver to perform
cluster communications processing on a secondary CPU, thus offloading
the primary CPU.
Allows PEdriver to process
cluster communications using a single CPU.
Reduces CPU cost by providing
a Fast Path streamlined code path for DSA and served blocked data operations.
