      Report de recerca
      Accés obert
      We develop efficient methods to check whether two given Context-Free Grammars (CFGs) are transformed into parsers that recognize the same language and construct the same Abstract Syntax Trees (ASTs) for each input. In this ...

    • Compiler automatic discovery of OmpSs task dependencies

      Text en actes de congrés
      Accés restringit per política de l'editorial
      In order to obtain maximum performance, many applications require to extend parallelism from multi-threading to instruction-level (SIMD) parallelism that exists in many current (and future) multi-core architectures. While ...

    • Extending Saiph to simulate fluid mechanics and chemistry problems
