awscrt.common

Cross-platform library for awscrt.

awscrt.common.get_cpu_group_count() → int

Returns number of processor groups on the system.

Useful for working with non-uniform memory access (NUMA) nodes.

awscrt.common.get_cpu_count_for_group(group_idx: int) → int

Returns number of processors in a given group.

awscrt.common.join_all_native_threads(*, timeout_sec: float = -1.0) → bool

Waits for all native threads to complete their join call.

This can only be safely called from the main thread. This call may be required for native memory usage to reach zero.

Parameters:

timeout_sec (float) – Number of seconds to wait before a timeout exception is raised. By default the wait is unbounded.
