Akka.net: Access remote Actors in Cluster

由 丶灬走出姿态 提交于 2019-12-07 05:21:46
问题 In an clustered environment I have a seed node and node1 and node2. From node1 I want to send a message to an Actor which has been created on node2. The local path to this node on node2 is akka:MyAkkaSystem/user/AnActor. Now I want to send a message from an Actor from node1 to this specific actor by using an ActorSelection like that: var actorSystem = ActorSystem.Create("MyTestSystem"); var c = actorSystem.ActorSelection("/user/ConsoleReceiver"); c.Tell("Hello World"); On node2 the actor has

Quartz Clustering - triggers duplicated when the server starts

由 江枫思渺然 提交于 2019-12-07 05:18:43
问题 We are facing an issue while using Quartz 2.1.6 with Spring 3.1 in a clustered setup (with the JDBC data store). Current context: Jobs and CRON triggers are defined in the spring configuration file (see below) overwriteExistingJobs property is set to true in SchedulerFactoryBean, so we don't get new job definitions added to the DB with each deployment. However, after each deployment in the cluster, it seems that each node re-creates the trigger data. For example, if we have 2 triggers

Error occurring in caret when running on a cluster

问题 I am running the train function in caret on a cluster via doRedis. For the most part, it works, but every so often I get errors at the very end of this nature: error calling combine function: <simpleError: obj$state$numResults <= obj$state$numValues is not TRUE> and Error in names(resamples) <- gsub("^\\.", "", names(resamples)) : attempt to set an attribute on NULL when I run traceback() I get: 5: nominalTrainWorkflow(dat = trainData, info = trainInfo, method = method, ppOpts = preProcess,

Invalid message signature when running OpenId Provider on Cluster

由 隐身守侯 提交于 2019-12-07 04:38:24
问题 Introduction We have an OpenID Provider which we created using the DotNetOpenAuth component. Everything works great when we run the provider on a single node, but when we move the provider to a load balanced cluster where multiple servers are handling requests for each session we get issue with the message signing as the DotNetOpenAuth component seems to be using something unique from each cluster node to create the signature. Exception DotNetOpenAuth.Messaging.Bindings

FOSS ASP.Net Session Replication Solution?

由 ◇◆丶佛笑我妖孽 提交于 2019-12-07 04:21:46
问题 I've been searching (with little success) for a free/opensource session clustering and replication solution for asp.net. I've run across the usual suspects (indexus sharedcache, memcached), however, each has some limitations. Indexus - Very immature, stubbed session interface implementation. Its otherwise a great caching solution, though. Memcached - Little replication/failover support without going to a db backend. Several SF.Net projects - All aborted in the early stages... nothing that

Can I emulate MS Compute Cluster Server on my dev machine?

由 大兔子大兔子 提交于 2019-12-07 04:17:10
问题 I have a project for a client that will consist of managing jobs on a MS Compute Cluster. I will be developing the application outside of their network, and would like a way to develop/debug my app without the need to be on their network. I am developing the app in C#, and all I have so far is the Microsoft Compute Cluster Pack SDK. 回答1: Maybe this webcast can help you out Event link 回答2: The webcast was helpful, in that it lead me to the MPI.Net API. MPI.Net will allow me to write an

SunGridEngine, Condor, Torque as Resource Managers for PVM

由 你说的曾经没有我的故事 提交于 2019-12-07 02:36:55
问题 Anyone have any idea which Resource manager is good for PVM? Or should I not have used PVM and instead relied on MPI (or any version of it, such as MPICH-2 [are there any other ones that are better?]). Main reason for using PVM was because the person before me who started this project assumed the use of PVM. However, now that this project is mine (he hasn't done any significant work that relies on PVM) this can be easily changed, preferably to something that is easy to install because

Matlab parallel processing using a network computer

由 …衆ロ難τιáo~ 提交于 2019-12-07 00:04:07
问题 I'm familiar with matlabpool , and parfor usage, but I still need to speedup the computation. I have a more powerful computer in my 1GB network. Both computers have R2010b, and have the same code and paths. What is the simplest way to use both computers for parallel computation? Example of the code I use today: --- main.m--- matlabpool('open', 3); % ... x = randn(1e5,1); y = nan(size(x)); parfor k = 1 : length(x) y(k) = myfunc(x(k)); end --- myfunc.m--- function y = myfunc(x) y = x; % some

Elasticsearch 5.0.0. cluster node not joining

Is my RabbitMQ cluster Active Active or Active Passive?

由 谁说我不能喝 提交于 2019-12-06 16:34:35
I have created a cluster consists of three RabbitMQ nodes using join_cluster command. i.e. rabbitmqctl –n rabbit2@MYPC1 join_cluster rabbit2@MYPC1 (currently the cluster runs on a single computer) Questions: In the documents it says there is one implemetation for active passive and one for active active. What did I configure? How do I know? How can it be changed? Is there a big performance trade off between Active Active & Active Passive? What is the best practice to interact with active/active? i.e. install a load balancer? apache that will round robin What is the best practice to interact
