Best Known Method: Avoid heterogeneous precision in control flow calculations

Best Known Method

Running an MPI program in symmetric mode on an Intel® Xeon® host and an Intel Xeon Phi™ coprocessor may deadlock in specific cases due to the heterogeneous precision in replicated control flow calculations. The advice is to determine the control flow only on one master MPI process.

The Issue

Intel MPI applications can be executed on multiple combinations of Intel Xeon processors and Intel Xeon Phi coprocessors. Four different execution models are supported:

  • Desarrolladores
  • Profesores
  • Estudiantes
  • C/C++
  • Fortran
  • Intermedio
  • Intel® C++ Compiler
  • Intel® MPI Library
  • MPI
  • computational accuracy
  • solver control
  • Mensaje pasa a interfaz
  • Arquitectura Intel® para muchos núcleos integrados
  • Computación en paralelo
  • Suscribirse a computational accuracy
