Solution for simple grid computing in local network

由 痞子三分冷 提交于 2019-12-24 10:39:23
问题 I'd like to develop a simple solution using .NET for the following problem: We have several computers in a local network: 10 client computers that may need to execute a program that is only installed on two workstations The two workstations that are only used to execute the defined program A server that can be used to install a service available from all previously described computers When a client computer needs to execute the program, he would send a request to the server, and the server

Framework recommendation needed on .NET or JAVA for Volunteer computing (internet nodes)

由 ぐ巨炮叔叔 提交于 2019-12-21 23:17:14
问题 I want client machines on internet who subscribe to my server to donate their idle cpu cycles.(Like SETI@Home) They would take jobs(work-units) from server to process, and send back results to the server. (This is the most simple description). The framework i need should allow me to define a job/task. Rest of things like communication, job execution/tracking, client binaries update etc. should be managed by framework. I evaluated Alchemi.NET a bit, but its not actively maintained, seems half

Why has JXTA been abandoned? Any alternatives out there?

问题 P2p/Grid Computing seem like a promising concepts. JXTA looks like the only all in one framework for it. Is there a reason this field is so sparsely pursued? 回答1: I have lead the release of JXTA 2.6 and 2.7 - JXTA is not completely abandoned. Some people have posted patches on the 2.6 branch and it could easily be merged with the 2.7 branch. There are many reasons why people did not carry on participating to JXTA: Oracle did not follow-up on their duties regarding project governance, which

parameter for shell scripts that is started with qsub

由 孤街醉人 提交于 2019-12-18 10:13:39
问题 how can I parametrize a shell script that is executed on a grid (started with qsub) ? I have a shell script, where I use getopts to read the parameters. When I start (qsub script.sh -r firstparam -s secondparam ..) this working script with qsub I receive error messages, qsub: invalid option -- s qsub: illegal -r value as qsub thinks the parameter are for itself. Yet I have not found any solution. Thanks 回答1: Using the qsub -v option is the proper way: qsub -v par_name=par_value[,par_name=par

Gridgain failover of master (sender) node

由 若如初见. 提交于 2019-12-11 07:05:49
问题 I am working on batch processing problem. Solution needs to handle failing hardware. There is master node (which initiates tasks executions) and worker nodes which execute the jobs. I know how failover of worker nodes works but I could not find any information about failover of master nodes. Whenever master node which started a task fails the whole task is canceled. Is there any way to finish task processing then? Could you suggest the best way of implementing failover of master node? Kind

PBS/TORQUE: how do I submit a parallel job on multiple nodes?

由 泄露秘密 提交于 2019-12-11 03:13:54
问题 So, right now I'm submitting jobs on a cluster with qsub , but they seem to always run on a single node. I currently run them by doing #PBS -l walltime=10 #PBS -l nodes=4:gpus=2 #PBS -r n #PBS -N test range_0_total = $(seq 0 $(expr $total - 1)) for i in $range_0_total do $PATH_TO_JOB_EXEC/job_executable & done wait I would be incredibly grateful if you could tell me if I'm doing something wrong, or if it's just that my test tasks are too small. 回答1: With your approach, you need to have your

How to create a Linux cluster for running physics simulations in java?

由 大憨熊 提交于 2019-12-03 07:52:35
问题 I am developing a scientific application used to perform physical simulations. The algorithms used are O(n3), so for a large set of data it takes a very long time to process. The application runs a simulation in around 17 minutes, and I have to run around 25,000 simulations. That is around one year of processing time. The good news is that the simulations are completely independent from each other, so I can easily change the program to distribute the work among multiple computers. There are

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . What are the significant differences between Cloud Computing and Grid Computing ? What are the precise definations and target application domains for both ? I'm looking for conceptual insights along with technicalities. Like Windows Azure is a Cloud OS, do we have anytihng such for Grid Computing ? In past I did
