Symmetric multiprocessing
Symmetric multiprocessing or shared-memory multiprocessing (SMP) involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices, and are controlled by a single operating system instance that treats all processors equally, reserving none for special purposes. Most multiprocessor systems today use an SMP architecture.
symmetric multiprocessing
<parallel> (SMP) Two or more similar processors connected
via a high-bandwidth link and managed by one {operating
system}, where each processor has equal access to I/O devices.
This is in contrast to the "compute server" kind of
parallel processor where a front-end processor handles all
I/O to disks, terminals and local area network etc.
The processors are treated more or less equally, with
application programs able to run on any or perhaps all
processors in the system, interchangeably, at the operating
system's discretion. Simple MP usually involves assigning
each processor to a fixed task (such as managing the file
system), reserving the single main CPU for general tasks.
OS/2 currently supports so-called HMP (Hybrid
Multiprocessing), which provides some elements of symmetric
multiprocessing, using add-on IBM software called MP/2. OS/2
SMP was planned for release in late 1993.

Elementary symmetric polynomial
HOMOGENEOUS SYMMETRIC POLYNOMIAL IN WHICH EACH POSSIBLE MONOMIAL OCCURS EXACTLY ONCE WITH COEFFICIENT 1
Elementary symmetric function; Elementary symmetric polynomials; Fundamental theorem of symmetric polynomials; Fundamental Theorem of Symmetric Polynomials
In mathematics, specifically in commutative algebra, the elementary symmetric polynomials are one type of basic building block for symmetric polynomials, in the sense that any symmetric polynomial can be expressed as a polynomial in elementary symmetric polynomials. That is, any symmetric polynomial is given by an expression involving only additions and multiplication of constants and elementary symmetric polynomials.

Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both the encryption of plaintext and the decryption of ciphertext. The keys may be identical, or there may be a simple transformation to go between the two keys.

<cryptography> As opposed to public-key cryptography, a
cryptographic method in which the same key is used to encrypt
and decrypt the message. Private-key algorithms include the
obsolescent Data Encryption Standard (DES), triple-DES
(3DES), the Advanced Encryption Standard (AES), also known
as Rijndael, Blowfish, Twofish RC2, RC4, RC5 and RC6.
A problem with private-key cryptography is that the sender and
the recipient of the message must agree on a common key via
some alternative secure channel.
Public-key cryptography gives an answer to this problem.

Symmetric Lie algebra; Symmetric Lie group
In mathematics, an orthogonal symmetric Lie algebra is a pair (\mathfrak{g}, s) consisting of a real Lie algebra \mathfrak{g} and an automorphism s of \mathfrak{g} of order 2 such that the eigenspace \mathfrak{u} of s corresponding to 1 (i.e.

Symmetric multiprocessing
Symmetric multiprocessing or shared-memory multiprocessing (SMP) involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices, and are controlled by a single operating system instance that treats all processors equally, reserving none for special purposes. Most multiprocessor systems today use an SMP architecture. In the case of multi-core processors, the SMP architecture applies to the cores, treating them as separate processors.
Professor John D. Kubiatowicz considers traditionally SMP systems to contain processors without caches. Culler and Pal-Singh in their 1998 book "Parallel Computer Architecture: A Hardware/Software Approach" mention: "The term SMP is widely used but causes a bit of confusion. [...] The more precise description of what is intended by SMP is a shared memory multiprocessor where the cost of accessing a memory location is the same for all processors; that is, it has uniform access costs when the access actually is to memory. If the location is cached, the access will be faster, but cache access times and memory access times are the same on all processors."
SMP systems are tightly coupled multiprocessor systems with a pool of homogeneous processors running independently of each other. Each processor, executing different programs and working on different sets of data, has the capability of sharing common resources (memory, I/O device, interrupt system and so on) that are connected using a system bus or a crossbar.
