6.3. INTERACTIVE OPTIONS: BALSAC/CLUSTER SESSION

next, previous Section / Table of Contents / Index BALSAC/CLUSTER sessions can be initiated by starting BALSAC with the session parameter "c" and without structure file input or by selecting [C] from the interactive startup menu, see Sec. 6.1, after which the prompt ========================================================================= BALSAC/CLUSTER 2.16 by K. Hermann (C) Copyright 1991-2005 /adapter info/ Select: [I]nteractive [R]esume [P]revious [F]ile ->[L]attice [?,]Quit =================================================================== 2 == shows. Here the adapter information reads "VGA graphics version" for DOS systems and "X.11/NNbit mode DISPLAY= nodeid" for Unix systems with NN denoting the color depth (2**NN colors) and nodeid giving the network name of the display. Note that nodeid will always be truncated to 32 characters while longer display names may be used internally. In the above menu option [I] starts BALSAC/CLUSTER in interactive mode to build a cluster from scratch going through the standard building sequence, see Sec. 3.3.2. [R] starts a BALSAC/CLUSTER session with structure and graphics input from the quicksave file 'balsac.plt'. If no file 'balsac.plt' exists in the working directory BALSAC complains with ERROR: opening file for structure input File= balsac.plt and prompts for the name of an external structure input file analogous to option [F]. [P] restores a previous BALSAC/CLUSTER session with structure and graphics input from the safety backup file 'balsac.svc'. This file is generated automatically whenever a BALSAC/CLUSTER session is finished correctly. It contains in addition to structure/graphics information also a complete copy of the initialization file. Thus, both structural data and the full graphics environment of the previous session can be restored. If no file 'balsac.svc' exists in the working directory BALSAC complains with ERROR: opening file for structure input File= balsac.svc and prompts for the name of an external structure input file analogous to option [F]. [F] prompts for a name Input file name ("+"=def,"-"=esc): of a structure input file fname to be used for input starting a BALSAC/CLUSTER session in batch mode where option parameters are taken from file fname. Here a 1-character dummy name "+" can be used for the quicksave file 'balsac.plt' while giving "-" as a file name finishes the BALSAC session. If file fname does not exists in the working directory BALSAC complains with ERROR: opening file for structure input File= fname and prompts for a different file name. [L] starts a BALSAC/LATTICE session showing a startup menu similar to the present one, see Sec. 6.2. [,] finishes the BALSAC session returning to the DOS or Unix command line. next, previous Section / Table of Contents / Index
