Interactive Compilation Interface

Interactive Compilation Interface is a 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 Interactive Compilation Interface rather than just read about it. In short: The Interactive Compilation Interface (ICI) is a plugin system with a high-level compiler-independent and low-level compiler-dependent API to transform production compilers into interactive research toolsets. It was developed by Grigori Fursin during the MILEPOST project.

Key takeaways

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

Reference excerpt

The Interactive Compilation Interface (ICI) is a plugin system with a high-level compiler-independent and low-level compiler-dependent API to transform production compilers into interactive research toolsets. It was developed by Grigori Fursin during the MILEPOST project. The ICI framework acts as a "middleware" interface between the compiler and the user-definable plugins. It opens up and reuses the production-quality compiler infrastructure to enable program analysis and instrumentation, fine-grain program optimizations, simple prototyping of new development and research ideas while avoiding building new compilation tools from scratch. For example, it is used in MILEPOST GCC to automate compiler and architecture design and program optimizations based on statistical analysis and machine learning, and predict profitable optimization to improve program execution time, code size and compilation time.

Developments ICI is now available in mainline GCC since version 4.5 ICI was extended during the Google Summer of Code'2009 to enable fine-grain program optimizations including polyhedral transformations, function level run-time adaptation and collective optimization.

Worked examples

Example 1 — a first encounter with Interactive Compilation Interface

Start with the simplest possible case. Write down what Interactive Compilation Interface claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 Interactive Compilation Interface 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 Interactive Compilation Interface 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 Interactive Compilation Interface

In research: Interactive Compilation Interface appears in 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 Interactive Compilation Interface 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: Interactive Compilation Interface is common in secondary-school and first-year university syllabi. It links to neighbouring topics Interfaces, so understanding it makes those chapters shorter.
In everyday life: Look for Interactive Compilation Interface 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.

Frequently asked questions

What is Interactive Compilation Interface in simple terms?

Why does Interactive Compilation Interface matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
