PPT-Concurrent Hashing and Natural Parallelism

Presented by Orit Mussel December 2016 Art of Multiprocessor Programming by Herlihy amp Shavit 1 Advanced Topics in Concurrent Programming Instructor Erez Petrank Outline. 1 WHY CHOOSE PARALLELISM Parallel construction also called parallelism shows that two or more ideas are equally important by stating them in grammatically parallel form noun lined up with noun verb with verb phrase In building concurrent FIFO queues this reasoning has led re searchers to propose combiningbased concurrent queues This paper takes a different approach showing how to rely on fetchandadd FA a less powerful primitive that is available on x86 process Up to this point the greatest drawback of cuckoo hashing appears to be that there is a polynomially small but practically signicant probability that a failure occurs during the insertion of an item requiring an expensive rehashing of all items in th By .

Fine-Grain Parallelism. Concurrent execution in multi-core environment at level of . Parallel structure (also called parallelism) is the repetition of a chosen grammatical form within a sentence. By making each compared item or idea in your sentence follow the same grammatical pattern, you create a parallel construction. Consider a set of data with N data items stored in some data structure. We must be able to insert, delete & search for items. What are possible ways to do this? What is the complexity of each structure & method ?. What is a hashing function?.
