Detailed Description

Usage:

dash::utils::Config::set("NCHUNKS", 1024);
size_t cfg_value = dash::utils::Config::get<size_t>("NCHUNKS");

Environment variables starting with 'DASH_' are automatically added.

Configuration keys ending in '_SIZE' allow to set sizes (bytes) in human-readable format, e.g. "2M" -> 2048. The parsed size in number of bytes is then stored in a separate configuration key <key name>="">_BYTES.

For example:

dash::utils::Config::set("CHUNK_SIZE", "4MB");
auto chunk_bytes = dash::utils::Config::get<size_t>("CHUNK_SIZE_BYTES");
