Scaling of time to broadcast an operation on 3D arrays in numpy

狂风中的少年 提交于 2019-12-10 13:33:30
问题 I am trying to broadcast a simple operation of ">" over two 3D arrays. One has dimensions (m, 1, n) the other (1, m, n). If I change the value of the third dimension (n), I would naively expect that the speed of the computation would scale as n. However, when I try to measure this explicitly I find that there is an increase in computation time of about factor 10 when increasing n from 1 to 2, after which the scaling is linear. Why does the computation time increase so drastically when going

Issue with broadcast using Boost.Asio

大憨熊 提交于 2019-12-06 08:46:22
问题 I apologize in advance if the question has been previously answered, but I've searched and found nothing that helps me. As indicated by the question's title, I'm trying to broadcast a package from a server to a set of clients listening for any message. The client will count the number of messages it receives during one second. The server side of things goes like this: class Server { public: Server(boost::asio::io_service& io) : socket(io, udp::endpoint(udp::v4(), 8888)) , broadcastEndpoint

AlarmManager object after turning off and on the phone

ぃ、小莉子 提交于 2019-12-05 08:57:49
In my app, I set an alarm AlarmManager alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE); ... PendingIntent pendingIntent = PendingIntent.getBroadcast(context, id, intent, PendingIntent.FLAG_UPDATE_CURRENT); ... alarmMgr.set(AlarmManager.RTC_WAKEUP, time.getTimeInMillis(), pendingIntent); It works fine unless I turn off and turn on the phone. To be more specific, let's say at 10:20, I set an alarm to 10:22 and I turn off and turn on the phone at 10:21, alarm won't work. What might be the problem? Is that a broadcast issue of the pendingIntent there or should I set some

How to implement live video broadcasting in C#?

风格不统一 提交于 2019-12-04 06:30:53
I want to plug a live video broadcasting facility to a website. I'm planning to use silverlight and C# but I'm very newbie in this topic. What is the best way to do this? Thanks in advance. Update: I have a camera. I want it to capture it and show on my website. Live. But I have no idea about what I must do inside. Tell me everything about the capturing, streams, api's, dll's, whatever else I need to know. Thanks. If you're on Windows, you may want to consider the free Windows Media Encoder 9 SDK ( http://www.microsoft.com/windows/windowsmedia/forpros/encoder/features.aspx ). The idea is that

How to broadcast in java network

白昼怎懂夜的黑 提交于 2019-12-04 04:38:42
Its my first time programing network in java. I was looking for a way to send to somehow broadcast to all nodes in the whole networking. To let them know of my existence. I'm trying to make a multiplayer network game, and I want the clients to be able to see all the games available to choose which one to join. I want to know how to broadcast from the server and also how to make the clients listen. Please make it simple, I'm a newbie :) Thanks in advance. To broadcast data packets, send them to the broadcast address of the given subnet (the last address of the subnet). The IP 255.255.255.255 is
