boost::serialization high memory consumption during serialization

由 浪尽此生 提交于 2019-12-21 04:32:07
问题 just as the topic suggests I've come across a slight issue with boost::serialization when serializing a huge amount of data to a file. The problem consists of the memory footprint of the serialization part of the application taking around 3 to 3.5 times the memory of my objects being serialized. It is important to note that the data structure I have is a three dimensional vector of base class pointers and a pointer to that structure. Like this: using namespace std; vector<vector<vector<MyBase

问题 I have implemented a routing protocol on an Android 1.6 mobile that uses wireless (ad-hoc) network in order to exchange messages. Now I would like to evaluate it under an energy consumption point of view, the base would be to try to calculate the energy wasted to transmit a single packet, do anybody has any idea how to do that? Software/hardware solutions are welcome! 回答1: I don't believe that any application will give you any form of meaningful result. You really need to be looking at a

问题 Is there a way to get the instant power consumption on an Android phone? Not a per process consumption, but an overall consumption. I need it to be accessible on an app to be associated with some settings on the phone at that time. Regarding the access of the information from an app, is it possible to get the PowerTutor data into my own app? 回答1: As commented by @adelphus, some devices have current info on /sys fs. There is a lot of comments about CurrentWidget code, available here. The link
