We have upgraded our single users IDL license to a 6 user license for
our IBM 550 running AIX 3.2.5. Since then we've found that with more
than about 3-4 simultaneous users, the AIX box turns into a slug.
Typically users are running IDL via X-windows, with the display on a
local workstation. Often these are the only user activity on this
machine. Disk I/O is minimal -- typically a few tps. The kernel cycle
sucker process doesn't get incremented from 9 a.m. to 5 p.m. This
machine seems to be very solidly cpu bound -- to the point that a
X-windows start up on the console with only xclock and aixterm takes 3-5
minutes.
1. Is there a way to speed up IDL?
2. Is there a compiler for IDL or converter for IDL -> Fortran or C
so that production code will run faster/can be run on other machines.
