          <datacite:description descriptionType="Other">筆者らは，非経験的分子軌道計算を高速に処理する専用並列計算機システム(EHPCマシン)に搭載するEric(二電子積分計算専用プロセッサ)の開発を行っている．二電子積分計算のアルゴリズムとして採用する小原のアルゴリズムの特徴を活かすことで高速処理が可能となる．本稿では，Ericの全体構成および動作について述べる．そして，現段階でのEricの性能評価を行う．</datacite:description>
          <datacite:description descriptionType="Other">We are developing a special-purpose processor(Eric) built in EHPC(Embedded High Performance Computing) computer system for ab initio Molecular Orbital Calculation to reduce the calculation time. Using characterization of two-electron integrals in the ``Obara method,'' it is possible to reduce the calculation time. In this paper ,we describe outline and operation of Eric for Molecular Orbital Calculation. Also, we evaluate the performance of Eric.</datacite:description>
