ieeexplore.ieee.org/iel5/4297461/4297462/04297606.pdf?arnumber=4297606 (Comparative Analysis of Debugging Tools in Parallel Programming for Multi-Core Processors) Introduction에서는 parallel programming의 이점을 아래와 같이 설명한다. Efficiency causes of parallel programming using: - increased performance - easy method to take advantage of multi-core; - better resource utilizatio..

ieeexplore.ieee.org/iel5/8608/27277/01213514.pdf 이 논문은 기존의 white noise방안과 제시하는 new heuristic방안을 비교한다. - white noise: 모든 혹은 임의 concurrent event의 before/after time에 noise를 invoke하는 방식 - new heuristic: 1. race condition상태의 shared variable을 찾아서 가장 access rate가 많은 변수를 뽑아 해당 변수에 대한 접..

pswlab.kaist.ac.kr/lab-orientation/concurrentbugpattern.ppt 1. Introduction ........ There can be two different types of bug patterns: those that involve an error introduced when implementing a design pattern that solves the problem well, and those that involve an error introduced when implementing an antipattern. ........ 2.2 Code Assumed to Be Protected - Nonatomic Operations Assumed to Be At..

ti.arc.nasa.gov/m/pub/archive/0886.pdf 도입부 1. Having new dual core or hyper-threaded processors in the personal computers, makes the testing of multi-threaded programs even more important 2. When the conditions of the bug are finally recreated the debugging itself may mask the bug(the observer effect) 3. The one most commonly associated with concurrent testing is race detection. Tool 분..

http://en.wikipedia.org/wiki/Distributed_system Distributed computing is a form of parallel computing, but parallel computing is most commonly used to describe program parts running simultaneously on multiple processors in the same computer. Both types of processing require dividing a program into parts that can run simultaneously, but distributed programs often must deal with heterogeneous env..

http://en.wikipedia.org/wiki/Thread_%28computer_science%29 On a single processor, Multithreading generally occurs by time-division multiplexing ("time slicing")in very much the same way as the parallel execution of multiple tasks: the processor switches between different threads. This context switching can happen so fast as to give the illusion of simultaneity to an end user. On a multiprocesso..
