Symmetric multiprocessing

Symmetric multiprocessing (SMP) involves a symmetric multiprocessor system hardware and software architecture where two or more identical processors connect to a single, shared main memory, have full access to all I/O 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.

SMP systems are tightly coupled multiprocessor systems with a pool of homogeneous processors running independently, each processor executing different programs and working on different data and with capability of sharing common resources (memory, I/O device, interrupt system and so on) and connected using a system bus or a crossbar.

Design

SMP systems have centralized shared memory called main memory (MM) operating under a single operating system with two or more homogeneous processors. Usually each processor has an associated private high-speed memory known as cache memory (or cache) to speed up the main memory data access and to reduce the system bus traffic.

Justin Timberlake

Justin Randall Timberlake (born January 31, 1981) is an American singer, songwriter, actor, and record producer. He appeared on the television shows Star Search and The All-New Mickey Mouse Club as a child. In the late 1990s, Timberlake rose to prominence as one of the two lead vocalists and youngest member of NSYNC, which eventually became one of the best-selling boy bands of all time. They released the albums NSYNC (1998), No Strings Attached (2000), and Celebrity (2001). During the group's hiatus, Timberlake released his debut solo album, the R&B-focused Justified (2002), which included the successful singles "Cry Me a River" and "Rock Your Body", and earned his first two Grammy Awards.

His second record, FutureSex/LoveSounds (2006), distinguished from his previous release by its wide range of musical influences, debuted atop the US Billboard 200 and produced the Billboard Hot 100 number-one singles "SexyBack", "My Love", and "What Goes Around... Comes Around". With his first two albums exceeding sales of 10 million copies worldwide, he was established as one of the most commercially successful singers of the decade. He also has collaborated with other artists, including Timbaland ("Give It to Me") and Madonna ("4 Minutes"). From 2008 through 2012, Timberlake focused on his acting career, effectively putting his music career on hiatus; he held starring roles in the films The Social Network, Bad Teacher, In Time, and Friends with Benefits.

Lady Gaga

Stefani Joanne Angelina Germanotta (/ˈstɛfəniː dʒɜːrməˈnɒtə/ STEF-ə-nee jur-mə-NOT-ə; born March 28, 1986), known professionally as Lady Gaga, is an American singer, songwriter, and actress. She is known for her self-empowering messages, fashion, and live performances. Gaga initially performed in theater, appearing in high school plays, and studied at CAP21 through New York University's Tisch School of the Arts before dropping out to pursue a musical career. After leaving a rock band, participating in the Lower East Side's avant garde performance art circuit, and being dropped from a contract with Def Jam Recordings, Gaga worked as a songwriter for Sony/ATV Music Publishing. There, recording artist Akon noticed her vocal abilities and helped her to sign a joint deal with Interscope Records and his own KonLive Distribution.

Her debut album The Fame (2008) was a critical and commercial success that produced global chart-topping singles such as "Just Dance" and "Poker Face". A follow-up EP, The Fame Monster (2009), was met with a similar reception and released the successful singles "Bad Romance", "Telephone", and "Alejandro". Her second full-length album Born This Way was released in 2011, topping the charts in more than 20 countries, including the United States, where it sold over one million copies in its first week. The album produced the number-one single "Born This Way". Her third album Artpop, released in 2013, topped the US charts and included the successful single "Applause". In 2014, Gaga released a collaborative jazz album with Tony Bennett titled Cheek to Cheek, which became her third consecutive number one in the United States. For her work in the television series American Horror Story: Hotel, Gaga won a Golden Globe Award in 2016.
