- Hello there,
- I am writing this post in the hope that some other NET people may have
- a solution for a problem we have at the moment.
-
- I work in a COMPUTATIONAL CHEMISTRY group and while we have our own
- machines to use we also have access to various other machines - in
- particular an INDIGO R4K and SGI4D -- which are used by other research
- groups for graphics to run AMBER, QUANTA
- and other graphics based programs.
-
- The problem is that they are only used
- for a small part of the day and certainly not at night. WE wish to
- soak up the excess CPU cycles by running GAUSSIAN and other cpu
- intensive programs in the background.
-
- Unfortunately when an interactive user comes along the terminal response
- is terrible, they get upset and we are forced to kill the background
- proccess.
-
- What we would really like is something that detects an interactive user
- and places the background process in sleep, frees up memory and will
- then allow better interactive terminal response. When the interactive
- user finishes their session and the terminal has been idle for a
- period of time or the interactive user has logged out the background
- session in sleep can be bought back to life again and the procesing
- takes off from where it left off.
-
- A program that suspends the background process may also be OK, so
- long as it is able to be started again from where it left off.
-
-
- Have you any ideas?
- It seems that something like this would (should) have been thought
- of before.
-
- Thanks for your time. Please either post any suggestions or email me
- directly to either of:-
