Function Documentation

GR_RUNTIME_API gr_thread_t gr::thread::get_current_thread_id ( )

Get the current thread's ID as a gr_thread_t.

We use this when setting the thread affinity or any other low-level thread settings. Can be called withing a GNU Radio block to get a reference to its current thread ID.

GR_RUNTIME_API void gr::thread::mask_signals ( )
GR_RUNTIME_API void gr::thread::set_thread_name ( gr_thread_t  thread,
std::string  name 
)
GR_RUNTIME_API int gr::thread::set_thread_priority ( gr_thread_t  thread,
int  priority 
)

set current thread priority for a given thread ID

GR_RUNTIME_API void gr::thread::thread_bind_to_processor ( const std::vector< int > &  mask)

Bind the current thread to a set of cores.

Wrapper for system-dependent calls to set the affinity of the current thread to the processor mask. The mask is simply a 1-demensional vector containing the processor or core number from 0 to N-1 for N cores.

Note: this does not work on OSX; it is a nop call since OSX does not support the concept of thread affinity (and what they do support in this way since 10.5 is not what we want or can use in this fashion).

GR_RUNTIME_API void gr::thread::thread_bind_to_processor ( int  n)

Convineince function to bind the current thread to a single core.

Wrapper for system-dependent calls to set the affinity of the current thread to a given core from 0 to N-1 for N cores.

Note: this does not work on OSX; it is a nop call since OSX does not support the concept of thread affinity (and what they do support in this way since 10.5 is not what we want or can use in this fashion).

GR_RUNTIME_API void gr::thread::thread_bind_to_processor ( gr_thread_t  thread,
const std::vector< int > &  mask 
)

Bind a thread to a set of cores.

Wrapper for system-dependent calls to set the affinity of the given thread ID to the processor mask. The mask is simply a 1-demensional vector containing the processor or core number from 0 to N-1 for N cores.

Note: this does not work on OSX; it is a nop call since OSX does not support the concept of thread affinity (and what they do support in this way since 10.5 is not what we want or can use in this fashion).

GR_RUNTIME_API void gr::thread::thread_bind_to_processor ( gr_thread_t  thread,
unsigned int  n 
)

Convineince function to bind the a thread to a single core.

Wrapper for system-dependent calls to set the affinity of the given thread ID to a given core from 0 to N-1 for N cores.

Note: this does not work on OSX; it is a nop call since OSX does not support the concept of thread affinity (and what they do support in this way since 10.5 is not what we want or can use in this fashion).

GR_RUNTIME_API int gr::thread::thread_priority ( gr_thread_t  thread)

get current thread priority for a given thread ID

GR_RUNTIME_API void gr::thread::thread_unbind ( )

Remove any thread-processor affinity for the current thread.

Note: this does not work on OSX; it is a nop call since OSX does not support the concept of thread affinity (and what they do support in this way since 10.5 is not what we want or can use in this fashion).

GR_RUNTIME_API void gr::thread::thread_unbind ( gr_thread_t  thread)

Remove any thread-processor affinity for a given thread ID.

Note: this does not work on OSX; it is a nop call since OSX does not support the concept of thread affinity (and what they do support in this way since 10.5 is not what we want or can use in this fashion).
