OpenSees can run sequentially and in Parallel on the resrces provided by Amazon EC2. Once the process is set up initially, the running of the applications is trivial (6 commands from the terminal and you could be running a parallel application on a remote Aamzon EC2 cluster of a few thousand nodes for a few dollars an hour .. and you get free hours through the education program if you are a student or educator. http://aws.amazon.com/education/awseducate/
The following are the 6 commands you would issue from your terminal window to run the file Example.tcl on a 100 node Amazon Cluster and obtain the results that the scipts created in the results folder back.
starcluser start smallcluster starcluster put Example.tcl /root starcluster sshmaster smallcluster mpiexec -n 100 OpenSees Example.tcl starcluster get /results /root/results starcluster terminate smallcluster
The first command starts the cluster. The second command will copy the file Eample.tcl to the remote machine. The third command will cause you to log on to your remote clusters 'master' node. The next command is the command you would issue on the remote machine to run a 100 processor job. The next command retrieves the contents of the /root/results directory. And lastly and an important command (assuming you don't want to use all your free allocation and go into bankruptcy) is the command to terminate the remote cluster.
The operation requires that:
- You log in with a credit card and obtain an Amazon EC2 account.
- You correctly install the StarCluster Software from MIT on your computer.
- Lastly you use the AMI that we have created for you in the StarCluster config file. The Amazon Ec2 AMI to specify is ami-e9ff1182 and is available in the US East Region.
The change to the config file is simply to swap out there ami and replace with ours. The NODE_IMAGE_ID lines should read:
NODE_IMAGE_ID = ami-e9ff1182
