不好意思 對作業系統不是很懂>< multiprocessor是像多cpu 交給不同的處理器做運算嗎 那multithread是分時而已嗎 還是如何達到好像同步進行 感謝Orz ※ 引述《liquidcrysta (crystal)》之銘言: : Hello people, : Apologize I can only type English for now. : I've been working on image processing and graphics application for a while, : and found that "think parallely" is critical to modern applications. : But I always have a question: : Do you think we should learn multithread coding (which I mean single/multicore) : before getting into parallel coding (which i mean gpgpu/multiprocessor)? : As my littile knowledge in these two fields, : multithread is to utilize the concept of "shared memory" rather than : speeding up by multicores, while parallel computing is intended to speed up : by the power of multiple processors. : I'm interested in how people compare with these two models. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 124.8.136.215
purincess:你是要講multiprocess"ing"還是multiprocess"or"阿 XD 10/15 02:13
purincess:要不要你先把thread跟process的區分搞清楚? 10/15 02:13
purincess:multithread的話corase-grained跟fine-grained都有點 10/15 02:14
purincess:分時進行的效果 但如果是simultaneous multithreading 10/15 02:14
purincess:就又不是了.... 10/15 02:14
purincess:啊我好像講得太architecture了 這裡是程式板= = 10/15 02:14
FAITHY:XD multiproces 10/15 02:15
FAITHY:網路上也查到一些了 把mutuprocessor和multiprocess搞混了 10/15 02:18
FAITHY:開兩個播放器 應該就是multiprocess的緣故...可以單核心.. 10/15 02:20
FAITHY:mutiprocess/thread主要都是分時.. 10/15 02:21
GreatShot:感覺原PO是想問 MPI vs. THREAD/OPENMP 10/15 02:48
GreatShot:個人覺得概念不太一樣,先學那種不衝突。 10/15 02:50
