Jetstream+Input+Parameters

Click here to return to top level Jetstream page.

This page is intended to be the single destination for information on the ever-evolving list of Jetstream input parameters. Developers are encouraged to add descriptions of parameters that they have created. Below are links to input parameter descriptions grouped by namelist as it appears in the input.param file (the default name for the file containing Jetstream input parameters):

**Main Parameter Types**
SOLVER OPTIMIZER MESH HYBROPT FILES PLANFORM OPPTS HOM Eigval

**Secondary Parameter Types**
(Used by several main parameter types but not used directly in Jetstream) ILUT LinSolvOpts LineSearch PTCLineSearch PCality

**Input Parameter File Formatting Notes**
Jetstream executables compiled for different architectures with different compilers may have different rules for formatting the input parameters file (e.g. input.param).

On the SciNet Power 7 machine the following formatting rules must be adhered to:
 * No spaces when specifying a derived data type variable name;
 * i.e. JTSTRM%GRAD_TOL = 1.d-6 is correct, but JTSTRM% GRAD_TOL = 1.d-6 will result in runtime error
 * The final namelist in the input parameters file must have a space after the closing &END
