JAGUAR COMPUTER
Mau tahu komputer super yang bikin China gregetan? Ya, namanya adalah Jaguar. Jaguar di sini bukanlah merk mobil mahal. Namun merupakan komputer super tercepat di dunia milik Amerika Serikat yang dapat melakukan banyak kegiatan dalam sehari. Saking banyaknya, komputer biasa hanya bisa menyelesaikannya dalam tempo 100 tahun.
Jaguar yang dibuat oleh perusahaan bernama Cray ini ditempatkan di laboratorium Nasional Oak Ridge di Tennessee, Amerika Serikat. Dikutip detikINET dari Telegraph, Kamis (3/6/2010), ia memiliki kecepatan sebesar 1,75 petaflops per detik. Satu petaflop setara dengan 1.000 triliun kalkulasi.
Komputer seharga US$ 120 juta ini telah digunakan oleh para ilmuwan untuk mensimulasikan ledakan bintang, aliran uranium ke sungai Columbia dari penyimpanannya di bawah tanah dan menampilkan dampak perubahan iklim.
Amerika memang menjadi rumah bagi setengah dari 500 superkomputer yang tercatat di dalam daftar International Supercomputing Conference. Namun rupanya China tak mau kalah. Sang Negeri Tirai Bambu pun ingin membuat komputer supercepat untuk menyaingi Jaguar.
China dengan komputer Nebulae-nya mampu bercokol di urutan kedua skala global dengan performa 1,271 petaflop per detik. China sendiri saat ini telah memiliki 24 superkomputer yang bercokol di negaranya.
Inggris sendiri juga mempunyai 38 dari 500 superkomputer tersebut. Komputer supercepat itu kini ditempatkan di Universitas Edinburgh. Para ilmuwan mengatakan bahwa superkomputer semakin sering digunakan secara komersial, terutama di sektor dirgantara dan pertahanan.
Ritel raksasa seperti Walmart bahkan memiliki sistem itu untuk melacak rantai suplai dagangan mereka. Para ahli juga mengatakan selain 500 superkomputer tersebut ada sejumlah mesin rahasia yang dimiliki setiap negara di dunia yang kecepatannya bisa jauh lebih besar.

Jaguar uses an external Lustre file system called Spider for all file storage. The file system read/write benchmark is 240 GB/s, and provides over 10 petabytes (PB) of storage.
Hundreds of applications have been ported to run on the Cray XT series, many of which have been scaled up to run on 20,000 to 150,000 processor cores.
The petaflop Jaguar seeks to address some of the most challenging scientific problems in areas such as climate modeling, renewable energy, materials science, seismology, chemistry, astrophysics, fusion, and combustion. Annually, 80% of Jaguar's resources are allocated through DOE's Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program, a competitively-selected, peer-reviewed process open to researchers from universities, industry, government, and non-profit organizations.
As of June 2010, the TOP500 list rates Jaguar as the world's most powerful supercomputer. It has the second fastest theoretical peak performance behind Nebulae in China
Jaguar is a petascale supercomputer built by Cray at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee. In November 2009, it was named as the world's fastest computer according to TOP500, the semiannual list of the world's top 500 supercomputers. The massively parallel Jaguar has a peak performance of just over 1750 teraflops (1.75 petaflops). It has 224,256 x86-based AMD Opteron processor cores,[1] and operates with a version of Linux called Cray Linux Environment. Jaguar is a Cray XT5 system, a development from the Cray XT4 supercomputer.
The Jaguar system has been through a series of upgrades since installation as a 25-teraflop Cray XT3 in 2005. By early 2008 Jaguar was a 263-teraflop Cray XT4. In 2008 Jaguar was expanded with the addition of a 1.4-petaflop Cray XT5. By 2009 the resulting system had over 200,000 processing cores connected internally with Cray's Seastar2+ network. The XT4 and XT5 parts of Jaguar are combined into a single system using an InfiniBand network that links each piece to the Spider file system.
Jaguar's XT5 partition contains 18,688 compute nodes in addition to dedicated login/service nodes. Each XT5 compute node contains dual hex-core AMD Opteron 2435 (Istanbul) processors and 16 GB of memory. Jaguar's XT4 partition contains 7,832 compute nodes in addition to dedicated login/service nodes. Each XT4 compute node contains a quad-core AMD Opteron 1354 (Budapest) processor and 8 GB of memory. Total combined memory amounts to over 360 terabytes (TB).
