IBM Release 1.93 manual World Group, Title, Verbose, Boundary, Subdomain

Page 19

Example: SIMULATOR /usr/local/tempest/tempest

SIMULATOR rexx d:\poems\fido\fidossh.cmd $h $f

TITLE

Give a title to the run. This title is printed in each file, and is also

 

used to generate names for the intermediate file and log file, and for

 

the postprocessor orders file. No default.

 

Syntax: TITLE Waveguide3a

 

 

 

 

VERBOSE

Turn on verbose output. Sometimes helpful in figuring out what’s

 

going on. It’s sufficiently verbose that it’s probably best to redirect

 

it to a file or a pager program such as less.

 

Syntax: VERBOSE on off

 

 

 

 

3.1.3. WORLD Group

BOUNDARY

Sets boundary conditions for a given axis to be either periodic

 

(PERIODIC) or mirror-symmetrical (SYMMETRY). Only one need

 

be set for each axis; if both are specified, they must be the same,

 

since symmetry applies at both sides in FIDO/TEMPEST. (Deprecated

 

boundary type ILLUM is the same as PERIODIC, and is provided

 

for backward compatibility with earlier versions of POEMS.)

 

Parameters: xmin xmax ymin ymax zmin zmax

 

Syntax: BOUNDARY <parameter> PERIODIC SYMMETRY

 

 

 

 

SUBDOMAIN

Defines a simulation domain. A domain is the portion of the

 

computational world assigned to one thread. Since the current

 

version of tempest runs on a single processor, all domains will be

 

joined together into one big tempest run. FIDO supports multithread

 

simulations, so you don’t lose anything by putting them in.

 

Parameter domain_name must not contain whitespace. For multiple-

 

host simulations, the SUBDOMAIN keyword takes an optional

 

hostname and base port number, indicating which host this

 

subdomain is to run on, and the name of a supervisor host whose

 

fido instance will control that host. If these parameters are not

 

supplied, the given subdomain runs on the local host. (The

 

supervisor parameter should not be supplied for the host in overall

 

control.) All subdomains running on a given machine must specify

 

the same supervisor, or a runtime error will result. Each
