libreoffice 에서 그래프 그리는데 버벅대서 찾아보다 보니 openCL 로 가속이 가능하다고 한다.
[링크 : https://hamonikr.org/board_bFBk25/54522]
근데 정작 그래프 그리는데에는 도움이 안된다.
그냥 셀들 계산이 많을때는 도움이 될 듯.
-----
설정 뒤져보니 OpenCL 선택사항이라는게 있는데
OpenCL 사용 가능한 상황이라면, 아래에서 "OpenCL 사용 허용" 에 체크하고 적용 혹은 확인 누르면
libreoffice 다시 시작 하냐고 물어보는데 다시시작하고
설정을 보면 OpenCL을 사용할 수 있습니다로 바뀐다.
물론 그전에 OpenCL 이 사용가능한지 확인하고 설치해야 한다.
clinfo 실행해서 Number of platforms 가 0이 뜨면 OpenCL 사용 불가능한 상태
| $ sudo apt install clinfo $ clinfo Number of platforms 0 |
[링크 : https://ask.libreoffice.org/t/unable-to-activate-opencl/45714/3]
intel 10세대 노트북에 내장형 밖에 없어서 intel opencl을 설치해준다.
| $ sudo add-apt-repository ppa:intel-opencl/intel-opencl $ sudo apt-get update $ sudo apt install intel-opencl-icd |

blob 으로 하면 저장은 되는데, 옵션을 주어서 파일 유형을 골라줘야 할 듯.

40MB/s 정도 나와서 설마했는데.. 무늬만 3.0이었나?
서로 다른 포트에 연결해봤는데 링크 자체가 480M로 뜬다.

동일 모델, 2021.06 제조품을 연결하니 5000M USB3.0...
칩셋도 바뀌었구만?

혹시 모르니.. RXNP / TXNP를 다시 땜질 해줘봐야 하나?
칩셋은 RTL8154. 8153과 보다 뒷 버전이라 더 좋을 줄 알았는데 8153은 USB3.0 8154는 USB2.0 모델이다.

라벨은 아래와 같이 다른데 인증번호가 같냐. 칩셋 바뀌면 새로 인증 받아야 하는거 아니었나? 그 와중에 칩셋도 바꾸다니 드럽네?

다이오드 쓰면 순방향 전압강하(0.7V) 정도 발생하고
대전류가 아니라면 순방향 전압강하가 작은 쇼트키 다이오드를 사용하면 무난
MOSFET을 이용하여 구성도 가능하나 회로 구성이 복잡해지고, 비용도 올라서 가볍게 쓰기는 무리

| 순방향 전압 (VF) 특성이 낮으며, 스위칭 특성이 빠르다는 장점이 있습니다.단, 누설 전류 (IR) 가 크므로 열 설계를 잘못하면 열 폭주가 발생한다는 결점 |

겁나 치열..
아무튼 어떻게 예매를 하길래 땡 치자마자 했는데 바로 매진..
손크로가 아닌 느낌인데
아니면 나 같은 개발자가 또 있는건가?
