Out of Memory #2

Closed bk5115545 closed 9 years ago

bk5115545 commented 9 years ago

Ok so it's time to actually manage memory. There are several ::TODO:: and a TODO which have things to do about freeing memory. Right now opencv whines when the usable addresses pass 4GB which is an issue if we want to deploy on a Raspberry PI (4GB) of ram.

Need to:

Free closed threads in Transformer.cpp
Free processed frames in Transformer.cpp
Free collected results in main

And there might be something else to free too...

Unfortunately, we will need to be more careful as the Raspberry PI only supports 1GB max (as of February 2015). Though we can find more luxurious alternatives.

Most of the memory issues are closed however we still leak 8 bytes every main loop iteration. We also leak 74 bytes every thread instantiation.

I need to look at these more.

Commit 992cbadb9733da78d779280c1db7b7c8df08a8e3 lowered memory usage by more than 800MB.

All known memory leaks were closed with commit bc26035574714d4235b42d51e8aba4dc15bb294a. We still have to watch out for a growing queue size in the thread pool job queue but that's another issue entirely.
