As part of our graphics research activity, the Princeton Interactive Computer Graphics Lab (ICGL) maintains a cluster of 16 Personal IRIS workstations which is available to students and faculty 24 hours a day. There are currently 675 users registered in our password file, although not all of these are continuously active users. One of the biggest system administration headaches we face is keeping a useful amount of disk space available to the users (and ourselves). This problem is exacerbated by the relatively larger size of programs compiled for the 4D's RISC processor, compared to a typical CISC executable. In desparation, we read the documentation. It turns out that there are some pretty painless mechanisms for reducing the size of a typical 4D executable. Kevin Perry (our systems programmer), recently compiled a moderate-size GL program with a variety of different cc command-line options, and noted the sizes of the resulting executables. Here are the results of this test: Compilation Cmd Executable Size cc -g test.c -lgl: 330 Kb (with symbol table, debugging) cc test.c -lgl: 330 Kb (with symbol table) cc -s test.c -lgl: 196 Kb (strip symbol table) cc -s test.c -lgl_s: 53 Kb (use shared GL library) cc -s test.c -lgl_s -lc_s: 33 Kb (use shared GL and C libraries) cc -s -O test.c -lgl_s -lc_s: 29 Kb (use optimizer) Note: The -g option is meaningless if combined with the -s option. So: we have found it useful to advertise the use of some of these options, and have changed our existing makefiles to take advantage of them. +---------------+ David Laur | "a bizarre | Princeton University | underwater | Interactive Computer Graphics Lab | scenerio..." | Internet: dmlaur@magritte.princeton.edu +---------------+ Bitnet: dmlaur@pucc
