Function Documentation

redset_abort()

void redset_abort	(	int	rc,
		const char *	fmt,
			...
	)

print abort message and kill run

redset_align_free()

void redset_align_free

(

void *

buf

)

frees a blocked allocated with a call to redset_align_malloc

redset_align_malloc()

void* redset_align_malloc	(	size_t	size,
		size_t	align
	)

allocates a block of memory and aligns it to specified alignment

redset_alltrue()

int redset_alltrue	(	int	flag,
		MPI_Comm	comm
	)

returns true (non-zero) if flag on each process in comm is true

redset_buffers_alloc()

		size_t	size
	)

redset_buffers_free()

void redset_buffers_free	(	int	num,
		void *	pbufs
	)

redset_dbg()

void redset_dbg	(	int	level,
		const char *	fmt,
			...
	)

print message to stdout if redset_debug is set and it is >= level

redset_err()

void redset_err	(	const char *	fmt,
			...
	)

print error message to stdout

redset_free()

void redset_free

(

void *

ptr

)

pass address of pointer to be freed, frees memory if not NULL and sets pointer to NULL

int redset_str_sendrecv	(	const char *	send_str,
		int	send_rank,
		char **	recv_str,
		int	recv_rank,
		MPI_Comm	comm
	)

sends a NUL-terminated string to a process, allocates space and recieves a NULL-terminated string from a process, can specify MPI_PROC_NULL as either send or recv rank

redset_warn()

void redset_warn	(	const char *	fmt,
			...
	)

print warning message to stdout
