The main advantages of a
message-passing standard like MPI are
portability and ease-of-use. In a distributed
memory communication environment in
which the higher level routines are built
upon lower level message passing
routines, the benefits of a standard are
apparent. Additionally, a message passing
standard provides vendors with a defined
base set of routines that can be imple-
mented efficiently, or in some cases
provide hardware support for, thereby
enhancing scalability.
MSI
Message signaled interrupts. One of two
PCI-defined extensions to support
message signaled interrupts (MSI), in PCI
2.2 and later and PCI Express. MSIs are
an alternative way of generating an inter-
rupt through special messages that allow
emulation of a pin assertion or desertion.
N_Port
Node port. A port that connects by a
point-to-point link to either a single N_Port
or a single F_Port. N_Ports handle
creation, detection, and flow of message
units to and from the connected systems.
N_Ports are end ports in virtual
point-to-point links through a fabric, for
example, N_Port to F_Port to F_Port to
N_Port using a single Fibre Channel fabric
switch.
N_Port ID virtualization

network time protocol

NIC
Network interface card. Computer card
installed to enable a dedicated network
connection.
NIC partitioning

non-volatile random access memory
See NVRAM.
NPAR
NIC partitioning. A feature in Marvell
adapters that allows you to partition a
single 10GbE NIC port into up to four
individual partitions with user-configurable
bandwidth and function type (or function
protocol). The partitioning options are not
limited to NIC as the name NPAR
indicates; it extends to converged fabric
partitioning by enabling you to assign
iSCSI or FCoE protocols to specific parti-
tions.
NPIV
N_Port ID virtualization. The ability for a
single physical Fibre Channel end point
(N_Port) to support multiple, uniquely
addressable, logical end points. With
NPIV, a host Fibre Channel Adapter is
shared in such a way that each virtual
adapter is assigned to a virtual server and
is separately identifiable within the fabric.
Connectivity and access privileges within
the fabric are controlled by identification of
each virtual adapter and, hence, the virtual
server using each virtual adapter.
NTP
Network time protocol. NTP is used for
distributing the Coordinated Universal
Time (UTC) by means of synchronizing the
clocks of computer systems over
packet-switched, variable-latency data
networks.
