GPUToolbox.jl

Common utilities shared between the various Julia GPU backends.

Functionality

This package currently exports the following:

• SimpleVersion: a GPU-compatible version number
• @sv_str: constructs a SimpleVersion from a string
• @checked: Add to a function definition to generate an unchecked and a checked version.
• @debug_ccall: like ccall but prints the ccall, its arguments, and its return value
• @gcsafe_ccall: like @ccall but marking it safe for the GC to run.
• cooperative_wait: wait for a GPU operation without blocking the calling thread, so that other tasks can run.
• Suffix literals like 1i8 (i8, i16, i32, u8, u16, u32) for constructing literals of a certain type.

It also provides GPUToolbox.Overlays, method tables with device overrides of Base functionality that GPU back-ends can share by stacking them underneath their own method table, and the tools back-ends use to define device-only functions and to check that no device code leaks into code compiled for the host. See the module's docstring for the design and how to use it.
