chapeliser

Scale single-machine apps to distributed clusters without learning Chapel.

Install

cargo install chapeliser

What It Does

Chapeliser is a general-purpose Chapel acceleration framework. Describe your workload in a chapeliser.toml manifest, point it at your code, and it generates the distributed scaffolding — Chapel coforall loops, data partitioning, result gathering, and the ABI/FFI bridge between your application and the Chapel runtime.

Features

• Manifest-driven — describe what to distribute in TOML, not how
• Idris2 ABI with formal proofs of data layout and partition safety
• Zig FFI bridge to Chapel runtime with zero runtime overhead
• Works with Rust, C, and Zig applications
• Scales from 1 node (local) to 256+ nodes (cluster)
• No Chapel expertise required

Quick Example

[workload]
name = "my-scanner"
entry = "src/batch.rs::scan_all"
partition = "per-item"
gather = "merge"

[scaling]
min-nodes = 1
max-nodes = 256
grain-size = 50
