PRIMEHPC FX10

PRIMEHPC FX10 is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand PRIMEHPC FX10 rather than just read about it. In short: The PRIMEHPC FX10 is a supercomputer designed and manufactured by Fujitsu. Announced on 7 November 2011 at the Supercomputing Conference, the PRIMEHPC FX10 is an improved and commercialized version of the K computer, which was the first supercomputer to obtain more than 10 PFLOPS on the LINPACK benchmark.

Key takeaways

PRIMEHPC FX10 belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect PRIMEHPC FX10 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of PRIMEHPC FX10 from memory before moving on to harder problems.

Reference excerpt

The PRIMEHPC FX10 is a supercomputer designed and manufactured by Fujitsu. Announced on 7 November 2011 at the Supercomputing Conference, the PRIMEHPC FX10 is an improved and commercialized version of the K computer, which was the first supercomputer to obtain more than 10 PFLOPS on the LINPACK benchmark. In its largest configuration, the PRIMEHPC FX10 has a peak performance 23.2 PFLOPS, power consumption of 22.4 MW, and a list price of US$655.4 million. It was succeeded by the PRIMEHPC FX100 with SPARC64 XIfx processors in 2015.

Specifications Node specifications: Theoretical peak performance: 236.5 GFLOPS Processor: One 1.848 GHz, 16-core SPARC64 IXfx Memory capacity: 32 or 64 GB Memory bandwidth: 85 GB/s Tofu Interconnect link bandwidth: 5 GB/s per direction (Tofu has dedicated links for each direction) System specifications: 4 to 1,024 racks 384 to 98,304 compute nodes Theoretical peak performance: 90.8 TFLOPS to 23.2 PFLOPS Total memory capacity: 12 TB to 6 PB Interconnect: Torus fusion (Tofu); 6D mesh/torus hybrid Cooling method: Direct water cooling and air cooling (with optional exhaust cooling unit) Operating System: Linux-based

Installations The first installation of the PRIMEHPC FX10 was at the University of Tokyo's Information Technology Center. Named Oakleaf-FX, the system has a peak performance of 1.135 PFLOPS and consists of 4,800 nodes (for a total of 76,800 cores) and 150 TB of memory in 50 racks. Oakleaf-FX was ordered in November 2011, and it became operational in April 2012. In June 2012 was ranked as the 18th fastest supercomputer in the 39th TOP500 list of the fastest supercomputers, with a LINPACK benchmark performance of 1.043 PFLOPS. In June 2012, Fujitsu received an order from Taiwan's Central Weather Bureau, the first PRIMEHPC FX10 sale outside of Japan. This system, which was installed in 2014, has a performance of over 1 PFLOPS. In addition to serving as a platform for high-performance computing, the PRIMEHPC FX10 was also intended to serve as a software development platform for the K computer, which it is compatible with. Fujitsu has sold several systems for K computer software development, including a 96-node system in June 2012 to Kobe University's Graduate School of Informatics, and 384-node system in August 2012 to the University of Tokyo's Institute for Solid-State Physics.

Worked examples

Example 1 — a first encounter with PRIMEHPC FX10

Start with the simplest possible case. Write down what PRIMEHPC FX10 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to PRIMEHPC FX10 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about PRIMEHPC FX10 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of PRIMEHPC FX10

In research: PRIMEHPC FX10 appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses PRIMEHPC FX10 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: PRIMEHPC FX10 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer engineering stubs, Fujitsu supercomputers, SPARC microprocessor products, so understanding it makes those chapters shorter.
In everyday life: Look for PRIMEHPC FX10 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
