Detailed Description

core (thread) specific APIs.

Currently OpenEM enumerates cores (threads) within an EM instance as contiguous integers starting from 0. Numbers may or may not match those provided by underlying HW or operating system.

Function Documentation

em_core_count()

int em_core_count

(

void

)

The number of cores running within the same EM instance (sharing the EM state).

Returns

Number of EM cores (or HW threads).

em_core_id()

Examples

em_core_id()

int em_core_id

(

void

)

Logical core id.

Returns the logical id of the current core. EM enumerates cores (or HW threads) to start from 0 and be contiguous, i.e. valid core identifiers are 0...em_core_count()-1

Returns

Current logical core id.
