Detailed Description

TOML-based pipeline configuration file support.

Loaded by Pipeline::loadConfig() / Pipeline(path) and written by Pipeline::saveConfig(). This header contains no toml++ types — the dependency is an implementation detail confined to config.cpp.

Supported stage type values: LorenzoQuant — fused float predictor+quantizer (cuSZ-style) Lorenzo — plain integer delta predictor (lossless, use after Quantizer) Quantizer — standalone float-to-integer quantizer Bitshuffle, RZE, RLE, Bitpack, Difference, Zigzag, Negabinary

File format: human-readable TOML v1.0

Minimal example:

[pipeline]
dims   = [3600, 1800, 1]
input_size = 25920000
 
[[stage]]
name            = "lorenzo"
type            = "LorenzoQuant"
input_type      = "float32"
code_type       = "uint16"
error_bound     = 1e-4
error_bound_mode = "ABS"
quant_radius    = 32768
outlier_capacity = 0.10
zigzag_codes    = true
 
[[stage]]
name        = "bshuf"
type        = "Bitshuffle"
block_size  = 16384
element_width = 2
inputs = [{ from = "lorenzo", port = "codes" }]
 
[[stage]]
name       = "rze"
type       = "RZE"
chunk_size = 16384
