I'm currently working on a cluster using the ClusterVisionOS 3.1. This will be my first time working with a cluster, so i probably haven't tried the "obvious". I can submit a single job to the cluster with the "qsub" command(this i got working properly) But the problem starts when submitting multiple jobs at once. I could write a script...
I need a little push in the right direction. Here's my problem: I have to create an ultra-reliable service that sends email messages to clients whose addresses are stored in txt file on FTP server. Single txt file may contain unlimited number of entries. Most often the file contains about 300,000 entries. Service exposes interface with ...
Hi there, guys! I am currently trying to implement a singleton service over WebLogic, using a WebLogic cluster. I've read some literature about clustered singleton services on WebLogic, and I know I have to implement weblogic.cluster.singleton.SingletonService interface on the object I want to clusterize as a singleton. import weblogic...
We're trying to move an ASP.NET MVC application, which uses DotNetOpenAuth OpenID Version 3.4.1, from a single server web garden to a physical server cluster held behind a hardware load balancer. Our old setup (OpenID RP working): Browser => SHTTP => Server => WebGarden => Nonce/Session Store Our new setup (OpenID RP not working): Br...
I'm using ruffus to write a pipeline. I have a function that gets called in parallel many times and it creates several files. I'd like to make a function "combineFiles()" that gets called after all those files have been made. Since they run in parallel on a cluster, they will not all finish together. I wrote a function 'getFilenames(...
Update: Ok, after getting past the fact that I did not have MSDTC set up as a cluster resource (doh!), I was able to run my program and all appeared well, but I was not able to successfully send messages to it. After digging I found that while the private queues were created on one node of the cluster, they were not on the other node (I...
What's the difference between distributed and cluster? ...
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...
The cluster managing software for managing clusters on a windows server 2005 cluster had a checkbox for "allow application to interact with desktop" when creating a generic application resource. This appears to be gone in the management software for server 2008 clusters. Does anyone know where this option, if it still exists, is? ...
Does anyone know of a step by step process of setting up a ColdFusion 9 cluster using IIS 7.5? Either failover or network load balance would be nice. Without IIS being clusterable in Windows 2008 R2, I'm not sure of the best means to configure the web server and ColdFusion service. Some of the things I'm looking for are..... With lo...
Right so i'm trying to use a C library in C++, never actually done this before i thought it would be a case of declaring the header includes under a extern "C" and setting the compile as flag to "default" but i'm still getting linker errors and think that the header file might have to be complied as a DLL. I have no idea really. Is it ...
I am working on my diploma thesis project. I have access to 32Node Dell poweredge HPC cluster system with Linux(Debian i think) installed on it. My first goal is to create web (PHP) app where logged users could see free and busy nodes, turn them on and off. I am planning to do something like this - write some cron daemon that would run e...
I have had multiple problems trying to use PP. I am running python2.6 and pp 1.6.0 rc3. Using the following test code: import pp nodes=('mosura02','mosura03','mosura04','mosura05','mosura06', 'mosura09','mosura10','mosura11','mosura12') def pptester(): js=pp.Server(ppservers=nodes) tmp=[] for i in range(2...
Hey all - I have to design and implement a Fortran routine to determine the size of clusters on a square lattice, and it seemed extremely convenient to code the subroutine recursively. However, whenever my lattice size grows beyond a certain value (around 200/side), the subroutine consistently segfaults. Here's my cluster-detection rout...
Hi, I'm trying to start erlang slave node on cluster and I receive "bash: erl: command not found" message. Though I have alias for erl. Here is what I actually do: [user@n001 ~]$ erl -rsh ssh -sname n001 Eshell V5.7.5 (abort with ^G) (n001@n001)1> slave:start_link("user@n002", n002, "-rsh ssh"). bash: erl: command not found...
I have a set of data points, each described by a dictionary. The processing of each data point is independent and I submit each one as a separate job to a cluster. Each data point has a unique name, and my cluster submission wrapper simply calls a script that takes a data point's name and a file describing all the data points. That sc...
is it bad to output many files to the same directory in unix/linux? I run thousands of jobs on a cluster and each outputs a file, to one directory. The upper bound here is around ~50,000 files. Can IO be limited in speed in light of this? If so, does the problem go away with a nested directory structure? Thanks. ...
Hi all, First of all, sorry for the vague title. Let me explain. At work we're currently using SunGrid I've been assigned a project to create a web interface wrapper for interacting with the engine. i.e. displaying users jobs, submitting jobs via a nice GUI etc. (most of the sgrid commands output xml which is nice) My question for yo...
In Tomcat 5.0.x you had the ability to set useDirtyFlag="false" to force replication of the session after every request rather than checking for set/removeAttribute calls. <Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster" managerClassName="org.apache.catalina.cluster.session.SimpleTcpReplicationMana...
Does anybody know a Java implementation of the DRMAA-API that is known to work with PBS/Torque cluster software? The background behind this: I would like to submit jobs to a newly set-up linux cluster from Java using a DRMAA compliant API. The cluster is managed by PBS/Torque. Torque includes PBS DRMAA 1.0 library for Torque/PBS that co...
