VSMP (virtual symmetric multiprocessing)
VSMP (virtual symmetric multiprocessing) is a method of SMP
(symmetric multiprocessing) in which two or more virtual processors
are mapped inside a single virtual
machine or partition.
This makes it possible to assign multiple virtual processors to a virtual machine on any host
having at least two logical processors. VSMP can be employed in conjunction with multithreading, which
is the ability of a program to concurrently manage multiple user requests.
In SMP, multiple programs are run by two or more processors that share a common OS
(operating system) and memory.
A single copy of the OS is in charge of all the processors. SMP systems are considered better than
MPP (massively
parallel processing) systems for online transactions in
which many users are likely to access the same database at
the same time.
