v0.1.4

Diff since v0.1.3

• A nested hard limit that an enclosing scope already enforces is no longer entered: with_restricted_threads inside a saturated @budgeted_threads loop drops from about 3 us to 0.25 us. Julia 1.11 and later; on 1.10 every scope is entered as before.
• New thread_limit(name): the hard limit the enclosing scopes put on a pool.
• GuardedPool guards must act for the whole process while held.

• perf: skip nested no-op limits; add thread_limit (#6) (@hakkelt)

• Register Strided's thread count as a counted pool

v0.1.2

Diff since v0.1.1

• quiesce_foreign_pools(): before a Threads.@threads region, registered pools can release Julia's threads, so the region does not wait for spinning workers of another threading library (#3).
• Soft thread defaults (with_thread_default): run a computation with every registered library at n threads by default, without capping the calls inside it the way a hard with_thread_budget would.
• Thread grants (with_thread_grant): let a call known to be large enough thread despite a soft default in force. Grants never override a hard limit.
• Park hooks (register_park_hook!, park_openblas): when a grant closes and a pool's count goes down, the library can release the cores its idle workers would otherwise keep spinning on.
• A pool is never parked while a partial hard limit is open, and a worker that another task's @batch holds is never parked (#4).

Diff since v0.1.0

Changes:

• New only allowlist keyword on with_thread_budget/with_restricted_threads/with_full_threads: only = (:blas, :mkl) restricts exactly those pools and leaves everything else untouched, even past this scope's own budget.

Merged pull requests:

• fix(scopes): honor exclude for counted pools, add only allowlist (#2) (@hakkelt)
