load-balancing

问题 I've been trying to increase the performance of my OpenMP solution which often has to deal with nested loops on arrays. Although I've managed to bring it down to 37 from 59 seconds of the serial implementation (on an ageing dual-core Intel T6600) I'm worried that cache synch gets lots of CPU attention (when the CPU should be solving my problem!). I've been fighting to set up the profiler so I haven't verified that claim but my question stands regardless. According to this lecture on load

问题 In some requests the $_SERVER['HTTP_HOST'] not exists. I researched on the causes and now I know that this occurs on HTTP 1.0 requests. I have 4 domains in many machines behind a load balancer on AWS EC2 and I don't have a idea how to solve this problem. This is important, because is a business rule. 来源： https://stackoverflow.com/questions/24044630/http-host-not-found-behind-load-balancer-on-ec2

问题 Is there a way to modify how R foreach loop does load balancing with doParallel backend ? When parallelizing tasks that have very different execution time, it can happen all nodes but one have finished their tasks while the last one still have several tasks to do. Here is a toy example: library(foreach) library(doParallel) registerDoParallel(4) waittime = c(10,1,1,1,10,1,1,1,10,1,1,1,10,1,1,1) w = iter(waittime) foreach(i=w) %dopar% { message(paste("waiting",i, "on",Sys.getpid())) Sys.sleep(i

问题 Internet Explorer 11 has problems showing the icons of bootstrap. With Opera, Firefox and Chrome it works perfectly, and it also works with Edge but the icons are not shown with IE in Edge mode or (10,9,8). Before I changed the website to https it worked all fine. I have this problem after changing it to ssl. Does anyone know what I can do in order to solve this problem (at Server - Microsoft Azure or at load balancer)? With IE (icons are not shown): With Firefox: 回答1: Looks like a problem

问题 My nginx.conf file currently has the routes defined directly: worker_processes auto; events { worker_connections 1024; } http { upstream wordSearcherApi { least_conn; server api1:61370 max_fails=3 fail_timeout=30s; server api2:61370 max_fails=3 fail_timeout=30s; server api3:61370 max_fails=3 fail_timeout=30s; } server { listen 80; server_name server_name 0.0.0.0; location / { proxy_pass http://wordSearcherApi; } } } Is there any way to create just one service in docker-compose.yml and when

问题 We have the following situation going on: Go to http ://website/ and click on a link to http ://website/appX Check that the cookie shows JSessionID with secure = NO. Open another browser window or tab and go to https ://website/ and click on a link to https ://website/appY. Check that the cookie shows JSessionID with secure = YES. Try to interact with the window/tab created in step 1. I'm getting a session expired... If we repeat the steps but use https ://website/appX instead of https :/

问题 We have got a normal WCF service which has a binding that looks like this: <wsHttpBinding> <binding name="ServiceBinding" receiveTimeout="00:10:00" sendTimeout="00:10:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxReceivedMessageSize="20971520" messageEncoding="Mtom" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <security mode="Message"> <message clientCredentialType="Windows" negotiateServiceCredential="true"

问题 I have nginx container running as a service in Docker Swarm inside user created overlay network. Both created with: docker network create --driver overlay proxy docker service create --name proxy --network proxy -p 80:80 nginx When accessing nginx site through a browser, in nginx access log remote address is logged as 10.255... formatted address, what I presume to be the Swarm load balancer address. The question is how to know/log the address of the end client accessing the site and not the

问题 I'm using ASP.NET MVC 4 to accept a video upload of up to 30 mb in size. Once the video is uploaded to the site, the video is then posted to a 3rd party web service using a HttpWebRequest. This upload to the 3rd party service must complete and return a response before my site can return a response to the browser. On Rackspace Cloud Sites, the load balancer has a 30 second timeout. If no response is returned from my site through the load balancer for 30 seconds, then load balancer returns a
