cluster-computing

I am using a python-matlab-bridge that calls MATLAB from python by starting it on a ZMQ socket. On my own computer, I hand the bridge the location of the executable (in this case MATLAB 2014B): executable='/Applications/MATLAB_R2014b.app/bin/matlab' and everything works as required and the printed statement is: Starting MATLAB on ZMQ socket ipc:///tmp/pymatbridge-49ce56ed-f5b4-43c4-8d53-8ae0cd30136d Now I want to do the same on a cluster. Through module avail I find there are two MATLAB versions (2015a and 2016b) available and located at the following path: /opt/ud/LOCAL/etc/modulefiles/matlab

I'm trying to force nodes into different clusters in force layout based on a certain attribute in the data like "group." I'm adapting the code from Mike Bostock's multi foci force layout example ( code , example ) and I've been successful in adding in my own data but I haven't been able to specify how many clusters there are and how to assign a node to a cluster. I'm relatively new to d3 and JavaScript and I haven't been able to find many examples of multi foci applications. Here's my d3 code, any help or input is appreciated: var width = 960, height = 500; var fill = d3.scale.category10(); d3

I've seen searching for a way to start docker on multiple physical machines and connect them to a hadoop cluster, so far I only found ways to start a cluster locally on 1 machine. Is there a way to do this? shankarsh15 You can very well provision a multinode hadoop cluster with docker. Please look at some posts below which will give you some insights on doing it: http://blog.sequenceiq.com/blog/2014/06/19/multinode-hadoop-cluster-on-docker/ Run a hadoop cluster on docker containers 来源： https://stackoverflow.com/questions/37267304/is-it-possible-to-start-multi-physical-node-hadoop-clustster

I followed the following instructions to set up a multi node kafka cluster. Now, how to connect to the zookeeper ? Is it okay to connect to just one zookeeper from the Producer/consumer side in JAVA or is there a way to connect all the zookeeper nodes ? Setting a multi node Apache ZooKeeper cluster On every node of the cluster add the following lines to the file kafka/config/zookeeper.properties server.1=zNode01:2888:3888 server.2=zNode02:2888:3888 server.3=zNode03:2888:3888 #add here more servers if you want initLimit=5 syncLimit=2 On every node of the cluster create a file called myid in the

Super EDIT: Adding the broadcast step, will result in ncols to get printed by the two processes by the master node (from which I can check the output). But why? I mean, all variables that are broadcast have already a value in the line of their declaration!!! (off-topic image ). I have some code based on this example . I checked that cluster configuration is OK, with this simple program, which also printed the IP of the machine that it would run onto: int main (int argc, char *argv[]) { int rank, size; MPI_Init (&argc, &argv); /* starts MPI */ MPI_Comm_rank (MPI_COMM_WORLD, &rank); /* get
