问题 I am currently working on a logging mechanism to be used with Scala, but I have run into an unexpected issue that has prevented me from actually working on it. In order to test functionality, I am looking to set-up a simple message passing ring. Within the ring, each node is an extension of a Scala Actor and is aware of it's immediate neighbors (previous/next). The ring construction is done as follows, with the parameter "nodes" being passed from a controller actor: def buildRing(nodes:Array

TPL Dataflow, alternative to JoinBlock limitations?

阅读更多关于 TPL Dataflow, alternative to JoinBlock limitations?

问题 I look for an alternative to JoinBlock which can be linked to by n-TransformBlocks and join/merge messages of all TransformBlock source blocks together in order to pass a collection of such on to another data flow block. JoinBlock does the job fine but it is limited to hooking up to 3 source blocks. It also suffers from quite a number inefficiencies (very slow to join even value types (ints) of 2 source blocks). Is there a way to have Tasks returned from the TransformBlocks and wait until all

I've seen benchmarks of Actor model implementations done in terms of their actors. For example, Akka actors are very lightweight (600 bytes per actor) and millions of them can be created. However, I've never seen a benchmark done in terms of message-passing throughput. For example, given some number of actors,

Well, the title's pretty much it: if I sat a non-techie/my mum/twelve-year old boy/cocker spaniel in front of you and asked you to explain actors to them, where would you start? I ask because my master's project involves them to a pretty large degree, and every other day someone asks me to tell them what I'm doing. When I'm talking to other people on my course it's not so bad—usually the concept is foreign but understandable—but recently my flatmate, a chemist, asked me to explain it to her, and to say I struggled would be a pretty humongous understatement. I'm looking for some sort of
