Memory Management
Memory Management
Do you need to worry about this? Unless your machine is showing signs of running out of memory the answer is no.
There is a simple way to tell if this is the case:
If the button bars are both green you have no problems. If either turn dark orange you may need to take some action.
The top one shows this D3PLOT process size as a proportion of available physical memory on the machine. If this exceeds about 85% (and goes dark orange) the performance of the code may start to degrade as it starts to page (use virtual memory, or "swap"), although it will continue to run.
The lower one shows swap space usage (by all applications) as a proportion of total swap space available on the machine. If this exceeds about 90% you may have to take action to free some space from elsewhere. (A machine with no free swap space will simply stop, and may need rebooting!)
There are alarms built into the code which will warn you if you are approaching either of these limits, so you don't have to keep checking memory consumption.
If a memory alarm pops up ...
-
The memory use of this process can be managed by controlling how much
data is stored in the results database, and also by changing the animation
display method.
- Swap space is used by all processes on your computer, and it may be possible to free space by shutting down other processes.
