Loop-level parallelism-Loop-level parallelism-Loop-level parallelism is a form of parallelism in software programming that is concerned with extracting parallel tasks from loops. The opportunity for loop-level parallelism often arises in computing programs where data is stored in random access data structures. Where a ... | milkshake721/2.1M-wiki-STEM |
Loop-level parallelism-Description-For simple loops, where each iteration is independent of the others, loop-level parallelism can be embarrassingly parallel, as parallelizing only requires assigning a process to handle each iteration. However, many algorithms are designed to run sequentially, and fail when parallel pr... | milkshake721/2.1M-wiki-STEM |
Loop-level parallelism-Example-Consider the following code operating on a list L of length n. | milkshake721/2.1M-wiki-STEM |
Loop-level parallelism-Example-Each iteration of the loop takes the value from the current index of L, and increments it by 10. If statement S1 takes T time to execute, then the loop takes time n * T to execute sequentially, ignoring time taken by loop constructs. Now, consider a system with p processors where p > n. I... | milkshake721/2.1M-wiki-STEM |
Loop-level parallelism-Example-Less simple cases produce inconsistent, i.e. non-serializable outcomes. Consider the following loop operating on the same list L. | milkshake721/2.1M-wiki-STEM |
Loop-level parallelism-Example-Each iteration sets the current index to be the value of the previous plus ten. When run sequentially, each iteration is guaranteed that the previous iteration will already have the correct value. With multiple threads, process scheduling and other considerations prevent the execution ord... | milkshake721/2.1M-wiki-STEM |
Loop-level parallelism-Dependencies in code-There are several types of dependences that can be found within code.

Loop-level parallelism-Types-DISTRIBUTED Loop DOALL Parallelism DOACROSS Parallelism HELIX DOPIPE ParallelismEach implementation varies slightly in how threads synchronize, if at all.

Loop-level parallelism-Types-DISTRIBUTED loop When a loop has a loop-carried dependence, one way to parallelize it is to distribute the loop into several different loops. Statements that are not dependent on each other are separated so that these distributed loops can be executed in parallel. For example, consider the ... | milkshake721/2.1M-wiki-STEM |
Loop-level parallelism-Types-DOALL parallelism DOALL parallelism exists when statements within a loop can be executed independently (situations where there is no loop-carried dependence). For example, the following code does not read from the array a, and does not update the arrays b, c. No iterations have a dependence... | milkshake721/2.1M-wiki-STEM |
Loop-level parallelism-Types-Let's say the time of one execution of S1 be TS1 then the execution time for sequential form of above code is n∗TS1 , Now because DOALL Parallelism exists when all iterations are independent, speed-up may be achieved by executing all iterations in parallel which gives us an execution time... | milkshake721/2.1M-wiki-STEM |
Loop-level parallelism-Types-The following example, using a simplified pseudo code, shows how a loop might be parallelized to execute each iteration independently.

Loop-level parallelism-Types-Let's say the time of execution of S1 and S2 be TS1 and TS2 then the execution time for sequential form of above code is n∗(TS1+TS2) , Now because DOACROSS Parallelism exists, speed-up may be achieved by executing iterations in a pipelined fashion which gives us an execution time of TS1... | milkshake721/2.1M-wiki-STEM |
Loop-level parallelism-Types-S1 must be executed sequentially, but S2 has no loop-carried dependence. S2 could be executed in parallel using DOALL Parallelism after performing all calculations needed by S1 in series. However, the speedup is limited if this is done. A better approach is to parallelize such that the S2 c... | milkshake721/2.1M-wiki-STEM |

Claves-History-Claves have been very important in the development Afro-Cuban music, such as the son and guaguancó. They are often used to play an ostinato, or repeating rhythmic figure, throughout a piece known as the clave.Many examples of clave-like instruments can be found around the world. | milkshake721/2.1M-wiki-STEM |
Claves-Technique-The basic principle when playing claves is to allow at least one of them to resonate. The usual technique is to hold one lightly with the thumb and fingertips of the non-dominant hand, with the palm up. This forms the hand into a resonating chamber for the clave. Holding the clave on top of fingernails... | milkshake721/2.1M-wiki-STEM |
Claves-Technique-A roll can be achieved on the claves by holding one clave between the thumb and first two fingers, and then alternating pressure between the two fingers to move the clave back and forth. This clave is then placed against the resonating clave to produce a roll. | milkshake721/2.1M-wiki-STEM |
Claves-Use in popular music-Among the bands to have used claves are the Beatles in their recording "And I Love Her" and The Who in their song "Magic Bus".
Claves are also utilized in the interstitial spaces of the Night Court theme. | milkshake721/2.1M-wiki-STEM |
Claves-Use in classical music-Many composers looking to emulate Afro-Cuban music will often use claves such as Arturo Márquez with Danzón No. 2 or George Gershwin with his Cuban Overture.
