The HPCA Test of Time (ToT) award recognizes the most influential papers published in prior sessions of the International Symposium of High Performance Computer Architecture (HPCA) each of whom have had significant impact in the field.

Every year, papers are nominated for the award, either by recommendation from members of the computer architecture community, or automatically if they meet a minimum citation count criterion. Winning papers are selected by the ToT Award Committee, and are announced at that year’s HPCA conference.
