If you wouldn't mind, I'd prefer to use the starcluster
) mailing list for
reporting any issues/questions you might have in the future.
Concerning your question, I'm guessing you mean is there a way to download the
StarHPC AMI as a standalone virtual machine image? If so, I know that you can
download the individual virtual machine files from S3 (ie the parts of the
volume created by ec2-bundle-vol and the likes) but I've never tried to unpack
them and get the vm running within a local Xen installation.
This is not to say it couldn't be done, but I certainly don't have any
experience with this. Regardless, the amount of money you'd save not storing a
10GB AMI on S3 you'd likely spend on the data transfer into S3 every time you
wanted to launch the AMI. Furthermore, the process of transferring the image
to s3, registering the AMI, and then launching the instance would make for an
insanely long boot time. Honestly, I don't see the benefit.
I typically do things the old fashioned way (launch instance, customize,
rebundle) and also utilize EBS for housing research/application data and also
applications themselves. Amazon allows you to create EBS volumes up to 1TB
each. You can then mount these volumes to the instance. Starcluster supports
this btw and nfs's the mounted EBS volume to all the nodes. Have a look at the
docs if you're interested in using this.
Interestingly enough, EC2 recently added support for booting from an EBS
volume which opens up the amount of data that can be stored on an instance/AMI
(up to 1TB). This feature is not available in the current stable version of
StarCluster. Needless to say, I'll be experimenting with this in the very near
Hope that helps,
