Function Documentation

get_host()

host_t* get_host	(	GList **	queue,
		uint8_t	num
	)

Gets a host for which there are at least num agents available to start new agents on.

Parameters

queue	GList of available hosts
num	the number of agents to start on the host

Returns

the host with that number of available slots, NULL if none exist

Definition at line 144 of file host.c.

host_decrease_load()

void host_decrease_load

(

host_t *

host

)

Decrease the number of running agents on a host by 1.

Parameters

host	the relevant host

Definition at line 113 of file host.c.

host_destroy()

void host_destroy

(

host_t *

host

)

Frees and uninitializes any memory associated with the host struct.

Parameters

host	The host to free the memory for.

Definition at line 66 of file host.c.

host_increase_load()

void host_increase_load

(

host_t *

host

)

Increase the number of running agents on a host by 1.

Parameters

host	The relevant host

host_init()

host_t* host_init	(	char *	name,
		char *	address,
		char *	agent_dir,
		int	max
	)

Creates a new host, and adds it to the host list.

Parameters

name	The name of the host
address	Address that can be passed to ssh when starting agent on host
agent_dir	The location of agent binaries on the host
max	The max number of agent that can run on this host

Returns

New host

Definition at line 48 of file host.c.

host_insert()

void host_insert	(	host_t *	host,
		scheduler_t *	scheduler
	)

Inserts a new host into the scheduler structure.

Parameters

host	the host that will be added to the scheduler
scheduler	the relevant scheduler struct

Definition at line 91 of file host.c.

host_print()

void host_print	(	host_t *	host,
		GOutputStream *	ostr
	)

Prints the information about a host to the output stream.

Parameters

host	the relevant host
ostr	the output stream to write to

Definition at line 125 of file host.c.

print_host_all()

static int print_host_all ( gchar *  host_name, host_t *  host, GOutputStream *  ostr  )

static

GTraversFunction that allows the information for all hosts to be printed.

Parameters

host_name	the string name of the host
host	the host struct paired with the name
ostr	the output stream that the info will be printed to

Returns

0 to cause the traversal to continue
