Tutorial I – Single-PE Programming

The first three lessons of the main sequence program a single PE. They teach the build and test workflow, the Tungsten you need for ordinary code, and how the PE's compute engine runs a loop and what that costs. Every later lesson builds on them: from lesson 4 on, PEs send data to each other, and each PE runs code of the kind written here.

Lesson	What it teaches
Lesson 1 — Hello, wafer!	Tungsten, Paint and Carbide; what make runs; bench.map and miget; the ; after let
Lesson 2 — Values, control flow and functions	Types, if and while, functions in an imported module, miset; where Tungsten differs from C
Lesson 3 — How a PE runs a loop: vector instructions and cycles	The cycle counter, descriptors and the listing, what makes a loop fast or slow, rounding in references
