GASP

AeroSoft's GASP (General Aerodynamic Simulation Program; version 4.2) has been ported to the SGI Altix platform and is available on Inferno. Version 4.2 features a new input format (xml) so that earlier (e.g. 4.1) input files can not be used. There is a gasp41to42 utility to convert input files but the conversion is not entirely robust and is not available for the Altix. If you have 4.1 files then you should run gasp41to42 on the (SGI or linux) machine you have been using.

In order to use GASP, you must be a member of the  "gasp"  group; if you had indicated that you would be using GASP, you were automatically added to the  group; otherwise you should Contact Us and request that you be added to the GASP group.

Example:  To use the GASP solver with GASP program information in the file  "my_gasp_program.xml", you could enter the following command:

      gasp --solve -i my_gasp_program.xml < /dev/null

Note: the  "/dev/null"  is included above to prevent stalling during program execution.

If you plan to use the GASP gui, log onto Inferno from a system running an X Windows System Server. If you are using a UNIX based desktop system that includes an X server, you may be able to use ssh to initiate your X Windows System session. For example, to begin an X session using the account  "my_inferno_id"  on Inferno, try the following command:

     ssh  -X  my_inferno_id@inferno.cc.vt.edu

Note:  When you start the GASP gui, you may receive the following message which can be safely ignored:
