Pin shard workers to CPU cores — pin_workers • shard

Best-effort worker pinning to improve cache locality and reduce cross-core migration. Currently supported on Linux only.

Usage

pin_workers(pool = NULL, strategy = c("spread", "compact"), cores = NULL)

Arguments

pool: Optional shard_pool. Defaults to current pool.
strategy: "spread" assigns worker i -> core i mod ncores. "compact" assigns workers to the first cores.
cores: Optional integer vector of available cores (0-based). If NULL, uses 0:(detectCores()-1).

Value

Invisibly, a logical vector per worker indicating success.

Examples

# \donttest{
affinity_supported()
#> [1] TRUE
