Singelton for querying the Pvm.
This singelton class represents the global state of the Parallel
Virtual Machine (PVM). During construction (this happens on first
call to any PVM++ function) all necessary internal information is
created and the current tasks is introduced to the PVM. Access to
the class is given by the global function const PvmClass& Pvm().
Task I() const
- returns a Task-instance representing the current task.
I.e. the task, this function is called from.
unsigned int NumOfArchs() const
- returns the Number of different architectures, that are present
on the pvm.
void Hosts(HostSet &Result) const
- a set of all hosts in the PVM is returned in the reference
parameter Result.
void Tasks(TaskSet &Result) const
- a set of all tasks currently running on the PVM is returned in
the reference parameter Result.
void Update() const
- this function handles all pending messages, for which receive
actions other than normal receive are defined. Such are message
handler, automatic unpack, swallow on receive. This is executed
automatically by all Send() and Receive*() commands of the
Struct and StructSet classes. If you have
message handlers installed, it is important to call this
function before using data, provided by such handlers. E.g. a
task gets messages from time to time, telling it, which tasks it
has to send messages to. It then has to provide this information
to the Send()-function. Send() calls Update(), but when the
message-handlers are invoked for the received message, this new
information can't be provided to the Send()-function, as the old
information is already there.
