Class representing a host in the PVM.

Public Methods

std::string	Arch () const returns the name of the architecture of this host.
	Host (unsigned int What) constructs a Host for the host with the host id What as used by PVM.
std::string	Name () const returns the name of the host.
bool	Running () const returns, whether the host is up and running and still part of the PVM.
void	Spawn (const std::string &Task, int Num, TaskSet &Result) const starts Num instances of the task with name Task on the current host and returns the set of started tasks in Result.
Task	Spawn (const std::string &Task) const starts the task with name Task on the host and returns the corresponding instance of Task
unsigned int	Speed () const returns the speed of this host.
void	Tasks (TaskSet &Result) const returns a list of all tasks, currently running on this host, in the reference parameter Result.
	operator unsigned int () const returns the host id as used by PVM.

Documentation

Class representing a host in the PVM.

This class represents a host, that is part of the PVM. Internally it just stores a pointer to a data structure, so it is save and fast to use it as a value parameter and as a function result as well. Requests to the PVM, like Name() are cached, so you don't need to cache yourself.

There is an ostream& operator<<( ostream& Stream, Host What ) defined as well. It outputs the host id as used by the PVM prepended by a "h".

Host(unsigned int What)

constructs a Host for the host with the host id What as used by PVM.

operator unsigned int () const

returns the host id as used by PVM.

std::string Name() const

returns the name of the host.

std::string Arch() const

returns the name of the architecture of this host.

unsigned int Speed() const

returns the speed of this host. It's the same as in PVM.

bool Running() const

returns, whether the host is up and running and still part of the PVM.

void Spawn(const std::string &Task, int Num, TaskSet &Result) const

starts Num instances of the task with name Task on the current host and returns the set of started tasks in Result. The PVM rules regarding the default search path apply.

Task Spawn(const std::string &Task) const

starts the task with name Task on the host and returns the corresponding instance of Task

void Tasks(TaskSet &Result) const

returns a list of all tasks, currently running on this host, in the reference parameter Result.

This class has no child classes.
