pvm_addhosts Scilab // Group Scilab function pvm_addhosts
NAME
pvm_addhosts - add hosts to the virtual machine.
CALLING SEQUENCE
[infos] = pvm_addhosts(hosts)
PARAMETERS
hosts : row of strings, naming the hosts to be added.
infos : row of integer, corresponding to the status for each host.
DESCRIPTION
pvm_addhosts adds the computers named in
to the configuration of computers making up the virtual machine. The
names should have the same syntax as lines of a pvmd hostfile (see man
page for pvmd3): A hostname followed by options of the form xx=y.
The array
can be checked to determine the status for each host. Values less than
zero indicate an error, while positive values are TIDs of the new hosts.
The status of hosts can be requested by the application using
pvm_config. If a host fails it will be automatically deleted from the
configuration. Using pvm_addhosts a replacement host can be added by the
application, however it is the responsibility of the application
developer to make his application tolerant of host failure. Another use
of this feature would be to add more hosts as they become available, for
example on a weekend, or if the application dynamically determines it
could use more computational power.
EXAMPLE
info = pvm_addhosts(["isostar","loop"])
