Typedef Documentation

typedef struct prt_thread_s prt_thread_t

VSA's worker thread. Represents a single CPU core or a collection of cores.

"finished" is a one-directional synchronization variable. Therefore declered volatile, but no need for atomic access.

Function Documentation

void prt_thread_delete

(

prt_thread_t *

thread)

Destroys a thread.

Parameters

thread

– The thread to destroy.

Definition at line 49 of file prt_thread.c.

prt_thread_t* prt_thread_new	(	int	rank,
		int	core,
		int	agent_rank
	)

Creates a new thread object.

Parameters

rank	– The local rank of the thread.
core	– The global rank of the thread.
agent_rank	- The rank of the communication agent.

Returns

A new thread object.

void* prt_thread_run

(

void *

thrd)

Implements the thread's processing cycle. If set, calls the thread warmup function. Barriers all threads. If the communication proxy is active, it participates in the barrier. Cycles through VDPs. Fires the ones that are ready. Removes the ones which burned out. Quits when the list of VDPs becomes empty. Saves the execution time.

Parameters

thrd	– The pointer to the thread object.
