Before I introduce MPI to implement the hybrid MPI/OpenMP application, it is run like that: <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Imex.exe -f cputest_rb_samg_best_the1stFAST2.dat -log -fgmres<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>But right now, I need to launch it with MPIEXEC. For example, I am using Intel MPI and plan to run it on two host nodes: ‘Dingjunc’ and ‘Sim-west’. I need to enter as follow: <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>mpiexec -hosts 2 dingjunc 2 sim-west 2 imex.exe <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>How can I pass the following parameters into imex.exe? <o:p></o:p></p><p class=MsoNormal> -f cputest_rb_samg_best_the1stFAST2.dat -log -fgmres<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Imex.exe cannot run well without above parameters. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I look forward to your points. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks indeed in advance. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Dingjun Chen<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>P.S. above mpiexec.exe is from the Intel MPI library.
