A k-uniform hypergraph H = (V, E) is called l-orientable, if there is an assignment of each edge e ε E to one of its vertices v ε e such that no vertex is assigned more than l edges. Let Hn,m,k be a hypergraph, drawn uniformly at random from the set of all k-uniform hypergraphs with n vertices and m edges. In this paper we establish the threshold for the l-orientability of Hn,m,k for all k ≥ 3 and l ≥ 1, i.e., we determine a critical quantity c*k,l such that with probability 1 − o(1) the graph Hn,cn,k has an l-orientation if c c*k,l, but fails doing so if c c*k,l. Our result has various applications including sharp load thresholds for cuckoo hashing, load balancing with guaranteed maximum load, and massive parallel access to hard disk arrays.
