1. 프로젝트 관련 실험
스크립트가 정확하게 돌아가지 않는 것 같아, 스크립트가 아니라 실제 명령어로 실험함.
총 다섯 번 측정해 결과 요약할 것.


2. gem5-gpu 소스 코드 및 벤치마크 설치 방법 익히기
gem5-gpu 빌드 방법을 정리함. gem5-gpu와 벤치마크를 다시 빌드함.
gem5-gpu에서 제공하는 벤치마크들을 확인, 빌드해봄.
빌드되지 않는 것이 몇 개 있음. 에러를 잡아야 함.
벤치마크가 너무 많은데 어떻게 모두 실행해볼 수 있나?


3. 영어 기사 읽기
1) Baffling Genetic Barrier Prevents Similar Animals from Interbreeding, Scientific American
Baffling Genetic Barrier Prevents Similar Animals from Interbreeding (baffle – 당황하게 만들다, 칸막이)
– He regularly shimmies 60 feet up into the treetops, where he gingerly plucks fledgling crows from their nests and lowers them to his team below. (shimmy – 엉덩이와 어깨를 흔들며 춤추다, 움직이다, gingerly – 조심조심, pluck – 머리카락, 눈썹 등을 뽑다)
– The crows present a puzzling question to biologists, which gets to the heart of what it means to be a species (puzzling – 곤혹하게 하는)
– Almost all of them are clustered in a small part of one chromosome. (chromosome – 염색체)
– Something within that segment of DNA stops black crows from mating with gray ones and vice versa, creating a tenuous mating barrier that could represent one of the earliest steps in the formation of new species. (tenuous – 보잘것없는)
– A deluge of genetic data in recent years suggests that interbreeding between species is more widespread than scientists ever imagined. (deluge – 폭우, 호우, 쇄도하다)
– Until recently, the study of speciation has focused on ecology and behavior out in the field, as well as mating experiments, but scientists now find themselves able to analyze the genomes of a menagerie of wild creatures, including closely related ones. (menagerie – 야생 동물들)
– The results — from studies of crows, butterflies, mosquitoes, fish and other organisms — suggest that the concept of species is even more muddled than we thought, and that genetic changes don’t always align with more visible ones, such as appearance. (muddled -뒤죽박죽을 만들다)
– Their parents feel differently, however, calling out from nearby treetops. (calling out – 소리지르다)
– So-called assortative mating, in which animals that look similar are more likely to mate with each other, is one of the causes of new species development. (assortative – 종류별로 나누는, 분류하는)
– They are now being raised in a new aviary in Sweden, where they are eating scientists out of house and home. (aviary – 새장)
– The crow hybrid zone — the narrow strip of land where the carrion and hooded crows intermingle — isn’t dramatic in any way. (intermingle – 사람, 생각, 색깔 등을 섞다)
– Scientists still don’t have a definitive answer. (a definitive answer – 결정적인 대답)

2) Pushing the Limits of Personalization, HBR
– Sometimes the value swap is that clear-cut, but for the most part, the trade isn’t nearly so equitable, as several new books point out. (clear-cut – 명백한)
– Christian Rudder argues in Dataclysm that although there’s been an uptick in public concern over loss of privacy, consumers are, for the most part, apathetic. (uptick – 약간의 증가, apathetic – 무관심한)
– Seemingly innocuous bread crumbs of information (what movies we like) or even data effluent (word-use frequency) can paint an astonishingly detailed portrait of a consumer and predict traits or behavior with eerie accuracy. (innocuous – 악의 없는, effluent – 오수, 폐수)
– None of these books suggests that the tide is turning against data collectors. (tide – 조류)
– The harder companies push, the more craven their policies, the more they screw up in disturbingly visceral ways, the more likely they’ll be to find themselves rejected by outraged and empowered consumers (craven – 비겁한, visceral – 본능적인)

3) Online Shopping Isn’t as Profitable as You Think, HBR
– Am I really suggesting that the growth of e-commerce will slow before it annihilates most physical retailing? (annihilates – 전멸시키다)
– Of course, that pesky “if historical trends continue” phrase generates ferocious debates. (pesky – 성가신, ferocious – 흉포한, 맹렬한)
