Am I the only one with this specific problems? Every thursday we have a course in theoretical meteorology and therefore several small Fortran programs are written by the students, producing output by NCARG via IDT tool. The malfunction occured today, when the students tried to show their results - last week, before this big catastrophy, all things run well and nothing has been changed in the Linuxulator config or in binaries. Today, only those machines running with a single CPU are capable using IDT! All SMP machines, either with or without SMP activated, fail in running IDT with a SIG 20. :>My machine is still suffering these problems when SMP support is enabled, and :>it should be noted that it hangs very much more quickly when using linuxemu :>(in my case opera, but also netscape).
