Publication record 1: Sam Son, Seung Yul Lee, Yunho Jin, Jonghyun Bae, Jinkyu Jeong, Tae Jun Ham, Jae W. Lee, and Hongil Yoon, "ASAP: Fast Mobile Application Switch via Adaptive Prepaging", in Proceedings of The 2021 USENIX Annual Technical Conference (ATC'21), Virtual Event, July 2021 평가는 Android 10의 Pixel 4/3a와 8개 앱에 한정된다. access-bit logging은 switch time을 최대 14 ms 늘리고 target management는 최악 40 ms CPU time을 쓴다. 오예측으로 anonymous/file-backed 각 약 10 MB의 추가 fetch가 발생할 수 있다. 대부분 initial rendering을 완료 지표로 썼고 full rendering callback은 YouTube만 제공했다. Technical interpretation: prefetch 대상이 file-backed와 anonymous이면 안정성이 다르므로 하나의 predictor가 아니라 각기 다른 학습/보정 속도를 써야 한다. ASAP: Fast Mobile Application Switch via Adaptive Prepaging 8개 앱에서 vanilla Android 10 대비 switch time: Pixel 4 평균 22.2%/최대 33.3%, Pixel 3a 평균 28.3%/최대 35.7% 감소. CPU와 disk bandwidth utilization이 평균 각각 39.8%, 25.2% 증가; 예측 정확도는 file-backed 79.3%, anonymous 68.4%. 메타데이터는 앱당 평균 약 800 KB. 메모리 압박 상태에서 앱 전환 시 file-backed page I/O와 zram anonymous page decompression이 demand fault로 직렬화되는 시간을 어떻게 줄일 것인가? lab prefetch 대상이 file-backed와 anonymous이면 안정성이 다르므로 하나의 predictor가 아니라 각기 다른 학습/보정 속도를 써야 한다.
