지금 미국 출장 중인데 정말 재미있는 자료가 하나 터졌네요. 바로 전 세계 슈퍼컴 top500 순위입니다. 한국 언론들은 이걸 왜 자세하게 소개하지 않는지 모르겠습니다. 블로그에 간단히 날것들을 나열해 봅니다. 판단은 여러 분들이~

The new No. 1 system, built by IBM for the U.S. Department of Energy’s Los Alamos National Laboratory and called “Roadrunner,” achieved performance of 1.026 petaflop/s—becoming the first supercomputer ever to reach this milestone. At the same time, Roadrunner is also one of the most energy efficient systems on the TOP500.

이미 지난 주에 두 차례에 걸쳐 소개한 대로 로드러너가 페타플롭스 시대를 열며 1등을 기록했습니다. 잘 아실테고...

슈퍼컴 '로드러너' 실물영상 공개…사양 상상초월

1초 1000조회 연산시대 개막…IBM 로드러너 등장

위 두가지 글을 참고하시면 사진과 실물 영상을 보실 수 있습니다.

한국은 top100 중에는 64위에 하나 있습니다. 텔레콤 쪽에서 쓰는 산업용이라고 하는데, 구체적인 기업명은 적시되어 있지 않네요. SKT 아니면 KT인가요? HP 제품이라는 점도 눈길을 끕니다.

이 밖에도 top500에서는 한국 장비가 130위에 하나 더 있습니다. 대전 KISTI에 있는 놈인데, 이건 리서치용입니다. 썬 장비입니다.

한국은 top500에서 슈퍼컴이 2대 밖에 없네요. 기상청 장비는 완전이 밀려 났습니다. 6개월 전 세계 500대 슈퍼컴퓨터 중엔 한국은 단 1대 뿐 이라는 기사를 쓸 때보다는 한대 더 늘었지만, 이거 영 체면이 안 섭니다... 엑셀파일 내려 받아서 일본이나 인도 좀 보세요. 단적으로 비교가 됩니다. 슈퍼컴을 국력의 척도라고 보기에는 힘들겠지만, 적어도 평가의 일부인 것은 분명합니다.

AMD에서는 자사 제품인 옵테론을 쓴 모델이 1등한 기념으로 보도자료도 배포했네요. 당연히 자랑스럽겠죠.. 인정합니다^^

세계에서 가장 빠른 슈퍼컴퓨터가 사용하는 프로세서는?

AMD 옵테론™ 프로세서!

- 세계 상위 5대 슈퍼컴퓨터 시스템 중 3대, 상위 20대 중 7대가 AMD 기반

- 상위 20대의 슈퍼컴퓨터 중 AMD 옵테론 프로세서 기반 시스템의 수가 다른 x86 프로세서 아키텍처보다 거의 2배 많아

2008년 6월 19일, 서울 – AMD 옵테론™ (AMD Opteron™) 프로세서 기반의 슈퍼컴퓨터가 전 세계 상위 500대의 슈퍼컴퓨터 순위를 발표하는 ‘Top 500’에서 세계 1위의 슈퍼컴퓨터로 인정받았다고 현재 독일에서 열리고 있는 국제 슈퍼컴퓨팅 컨퍼런스를 통해 AMD가 발표했다. 해당 슈퍼컴퓨터에 사용되고 있는 AMD의
