Exploratory allocations equivalent to about 20k core hours are available on request
Significantly larger allocations require a proposal: note that the exploratory allocation can be used to document performance of a code, strengthening the proposal

Provides up to 3 million core hours for NSF-supported researchers, with a relatively simple proposal required.
