Syntax: PRINT <"string"> <expression> ....
RANDOMSEED Supply a seed to the pseudorandom number generator.
Pseudorandom numbers are used only to choose starting points for
the optimizer. The points visited by the optimizer for a given
problem can be changed by choosing a different seed.
Syntax: RANDOMSEED <expression>
The value of <expression> must be in [0, 999,999,999], and its value
is rounded to an integer before use. Thus values must round to
different integers for them to be distinct for this purpose.
Example: RANDOMSEED 314159265
SET Defines a variable and sets its initial value. The expression may
contain literals, arithmetic and logical operators, predefined
functions, and user functions.
Syntax: SET name = <expression>
Example: set hypot=sqrt(a*a+b*b)
SIMULATOR Give POEMS a simulator command line to use (no default). For
single-host simulations, this is just the simulator executable, but for
clusters, it should consist of a command processor, script name, and
any additional variables expected by the cluster script. To make
this easier, POEMS defines two special variables, as follows.
Name Expands To
$h Name of a file containing a list of all hosts actually used in
the simulation, one host per line
$f Name of a file containing a list of all files that need to be
distributed to the compute hosts for the current simulation.
POEMS constructs the command line by appending an at-sign (@)
and the name of a file containing the input parameters expected by
FIDO, then passes the resulting command line to the current shell.
The script blocks until the simulation returns.
Syntax: SIMULATOR <filename> [ <special variable> [<special
variable> ]]
