Calling the web service creates latency, which is important to avoid whenever possible. Also, my app is only allowed to make a certain

问题 According to the example in the manual of 'Robot Framework', in order to provide keywords from a remote computer one has to instantiate RobotRemoteServer with an instance of the class implementing the Keywords RobotRemoteServer(ExampleRemoteLibrary(), *sys.argv[1:]) What if I have multiple libraries/classes which I want to be available remotely? Do I have to start a new server for each class? Is robot framework suitable for automated distributed testing, where multiple computers have to run

问题 I am planning to decide on how many nodes should be present on Kafka Cluster. I am not sure about the parameters to take into consideration. I am sure it has to be >=3 (with replication factor of 2 and failure tolerance of 1 node). Can someone tell me what parameters should be kept in mind while deciding the cluster size and how they effect the size. I know of following factors but don't know how it quantitatively effects the cluster size. I know how it qualitatively effect the cluster size.

问题 I've read a lot on evenly distributing elements using css but every solution i've found requires you to know and define the width and/or the number of elements being distributed. I have a container that is of a fixed width - within here could be any number of li elements of an automatic width which need to be distributed evenly across the parent element from left to right. Here is my markup - except there could be any number of tabs with any length text in them. <ul class="tabs"> <li class=

问题 I have multiple 4GB GPU nodes so I want them to run huge model in parallel. I hope just splitting layers into several pieces with appropriate device scopes just enables model parallelism but it turns out that it doesn't reduce memory footprint for master node(task 0). (10 nodes configuration - master: 20g, followers:2g, 1 node configuration - master: 6~7g) Suspicious one is that gradients are not distributed because I didn't setup right device scope for them. my model is available on github.

问题 Why multi-paxos is called multi-paxos? I can't see how it is "multi". 回答1: It's about multiple rounds of the algorithm to agree sequential requests from a stable leader with minimal messaging. Initially with no recognised leader you must run at least one round of basic Paxos where a candidate leader sends a prepare request (using the terminology of the paper Paxos Made Simple). Positive responses from a majority confirm it as leader. It then sends accept messages for that round which

问题 Does the .thrift file reside in the Server side or the client side of the application? What is actual purpose of .thrift file in an Apache Thrift based application? Is it only used for generating minimal source codes for the application, or, does it have any other use? Can't I just write client-server codes myself without taking the help of .thrift file? 回答1: The *.thrift file is an IDL file, where IDL stands for Interface description language. The main purpose of this file is to generate the
