PSSC Labs

PSSC Labs 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 PSSC Labs rather than just read about it. In short: PSSC Labs is an American company based in Lake Forest, California, that develops high-performance computing hardware. Its servers, clusters, and workstations are used for scientific research and government applications.

Key takeaways

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

Reference excerpt

PSSC Labs is an American company based in Lake Forest, California, that develops high-performance computing hardware. Its servers, clusters, and workstations are used for scientific research and government applications. The company has implemented clustering software from NASA Goddard's Beowulf project in its supercomputers designed for bioinformatics, medical imaging, and computational chemistry.

History PSSC Labs was founded in 1984 by Larry Lesser. In 1998, it manufactured the Aeneas Supercomputer for Dr. Herbert Hamber of the University of California, Irvine (the physics and astronomy department); it was based on Linux and had a maximum speed of 20.1 Gigaflops. In 2005, PSSC Labs demonstrated its new water-cooling technology for high-performance computers at the ACM/IEEE Supercomputing Conference in Seattle, Washington. In 2007 the company announced products targeting life-science research: full-genome data analysis, including assembly, read mapping, and analysis of large amounts of high-throughput DNA and RNA sequencing data. In 2008 PSSC Labs designed the Powerserve Quattro I/A 4000 supercomputer for genome sequencing.

Worked examples

Example 1 — a first encounter with PSSC Labs

Start with the simplest possible case. Write down what PSSC Labs 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 PSSC Labs 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 PSSC Labs 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 PSSC Labs

In research: PSSC Labs 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 PSSC Labs 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: PSSC Labs is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1984 establishments in California, Cloud computing providers, Companies established in 1984, so understanding it makes those chapters shorter.
In everyday life: Look for PSSC Labs 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.
