Hitachi SR8000

Hitachi SR8000 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 Hitachi SR8000 rather than just read about it. In short: The Hitachi SR8000 is a high-performance supercomputer manufactured by the Hitachi c. 2001. It comprises 4 to 512 nodes, each containing multiple Hitachi RISC microprocessors.

Key takeaways

Hitachi SR8000 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 Hitachi SR8000 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Hitachi SR8000 from memory before moving on to harder problems.

Reference excerpt

The Hitachi SR8000 is a high-performance supercomputer manufactured by the Hitachi c. 2001. It comprises 4 to 512 nodes, each containing multiple Hitachi RISC microprocessors. Cooperative microprocessors are assigned to the same address space for synchronicity within each node. In 2002, Yasumasa Kanada calculated the decimal expansion of pi to 1.24 trillion digits using this model.

Worked examples

Example 1 — a first encounter with Hitachi SR8000

Start with the simplest possible case. Write down what Hitachi SR8000 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 Hitachi SR8000 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 Hitachi SR8000 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 Hitachi SR8000

In research: Hitachi SR8000 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 Hitachi SR8000 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: Hitachi SR8000 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer hardware stubs, Hitachi supercomputers, so understanding it makes those chapters shorter.
In everyday life: Look for Hitachi SR8000 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.
