Configure settings for Parallel Computing Toolbox client session
pctconfig('p1',v1,...)
config = pctconfig('p1',v1,...)
config = pctconfig()
| Property to configure. Supported properties are
|
| Value for corresponding property. |
| Structure of configuration value. |
pctconfig('
sets the client configuration property p1',v1,...)p1 with the value
v1.
Note that the property value pairs can be in any format supported by the set function, i.e., param-value
character vector pairs, structures, and param-value cell array pairs. If a structure
is used, the structure field names are the property names and the field values
specify the property values.
If the property is 'portrange', the specified value is used to
set the range of ports to be used by the client session of Parallel Computing Toolbox™ software. This is useful in environments with a limited choice of
ports. The value of 'portrange' should either be a 2-element
vector [minport, maxport] specifying the range, or
0 to specify that the client session should use ephemeral
ports. By default, the client session searches for available ports to communicate
with the other sessions of MATLAB®
Parallel Server™ software.
If the property is 'hostname', the specified value is used to
set the hostname for the client session of Parallel Computing Toolbox software. This is useful when the client computer is known by more
than one hostname. The value you should use is the hostname by which the cluster
nodes can contact the client computer. The toolbox supports both short hostnames and
fully qualified domain names.
config = pctconfig('
returns a structure to p1',v1,...)config. The field names of the structure
reflect the property names, while the field values are set to the property
values.
config = pctconfig(), without any input
arguments, returns all the current values as a structure to
config. If you have not set any values, these are the
defaults.
View the current settings for hostname and ports.
config = pctconfig()
config =
portrange: [27370 27470]
hostname: 'machine32'Set the current client session port range to 21000-22000 with
hostname fdm4.
pctconfig('hostname','fdm4','portrange',[21000 22000]);
Set the client hostname to a fully qualified domain name.
pctconfig('hostname','desktop24.subnet6.companydomain.com');
The values set by this function do not persist between MATLAB sessions. To
guarantee its effect, call pctconfig before calling any other
Parallel Computing Toolbox functions.
