Hi everyone,
yesterday i read an article into a french linux journal that in
some years garbage collector will disapear.
Why ? he explain in very very short as:
--------------------------
- Moore's law will be not anymore true
so only memory will continue to increase ( static and volatil )
- Garbage Collector are not efficient in big memory for some
technical reason
- Data to manage will continue to grow big data ant full memory
stategy will the rule
So Develloper will move to a language where they are no garbage
collector.
--------------------------
In bioinformatic we work with big data or full memory stategy
often and that will not stop. So what think D garbage
cllector's dev about this ?
Yes, I got this gist from hardware researchers repeatedly. Buzz
phrases like "all computing is low power computing now" get
thrown around. You can google "dark silicon" for more details.
However, your summary (or the article) is not quite correct.
Garbage collection is not efficient in little-memory scenarios
(embedded systems). Good, efficient garbage collection often
requires a few times as much memory as manual memory management.
This means if your application needs lots of RAM, you might be
able tackle bigger tasks, if you get rid of the garbage collector.
Also, be careful about the problem domain. There will be enough
domains left in some years, where garbage collection is the
better tradeoff. Just think about all the domains where
Python,Ruby,etc are popular now. The interesting field is mobile,
though. Android's Dalvik and Web Apps use garbage collection. iOS
switched to compiler-supported reference counting a few years
ago. Mobile means saving battery is important, so efficiency is
important. However, battery life is not the biggest factor for
consumers.
