Describe how many CPU hours you will need for using cloud computing on an ongoing basis *<br />

Virtual machines are a popular mode <strong>of</strong> operation in cloud computing that tends to affect some applications<br />

in terms <strong>of</strong> performance. Will this affect your application. Please specify *<br />

• Yes, I anticipate it will run slower but the other features <strong>of</strong> cloud computing make it more<br />

attractive to me<br />

• Yes, it can be a problem<br />

• No<br />

• Maybe<br />

• Don't know<br />

Cloud computing relies on pre-configured images for the OS and s<strong>of</strong>tware. The nodes do not have any<br />

persistent state. Check all that apply that affects your application. *<br />

• My code-base changes <strong>of</strong>ten and I need to recompile my code periodically.<br />

• The data is updated <strong>of</strong>ten<br />

• I need to save large amounts <strong>of</strong> data from each run<br />

Will there be other users or collaborators who can use your cloud setup to run their experiments *<br />

• Yes<br />

• No<br />

• Maybe<br />

Are there others in your scientific community interested in or looking at cloud computing *<br />

• Yes<br />

• No<br />
