Hi Shameer,


If you already have a cluster setup and running and you also have a
dedicated web server that can reach the head node of your cluster in the
network, then your job is simple.


All you have to do is install and cluster resource manager and scheduler. 

Below is a list of few open source tools you could use.



If what you wish is a simple FIFO queue and no complications, then the
choice would be SLURM.

It is very simple to port and install SLURM on a linux cluster.


Just three steps.


1.       Install SLURM.

2.      At the web server, convert the query into a linux shell script that
can run independently.

3.      Submit the job to the head node of the cluster using srun command of
the SLURM utility.


You can check with the documentation of this utility at

Hope this helps.


Happy new year!

Dear All,


Currently we are developing an Integrated Web Server for protein sequence

and structure analysis.

We are planning to provide a dedicated cluster to support the server.


I need help to set up a web application that can manage the web server and

our cluster.

For example  if the user is submitting a huge set  of sequence for MSA, the

program should take care of

the process and pass it on to the cluster and display the status of the job

(que and other details).

I know this is possible and people are doing it for example (Robetta



It will be great, If any of the BioIT techies around can help me out with

some help :))


We are using Ganglia as the server management tool. Web  Server is apache

running on  CentOS4 .


Thanks in Advance and Happy New Year to all...
