<DIV>Hi Jayesh,</DIV>
<DIV> </DIV>
<DIV>This time it seems itīs going to work. I have modified the "mpi2.bat" file, now it is:</DIV>
<DIV> </DIV>
<DIV> <EM>C:<BR>cd \Program Files\MPICH2\bin\</EM></DIV>
<DIV><EM></EM> </DIV>
<DIV><EM>mpiexec -n 1 D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster\Prueba32-01 : -n 1 D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster1\Prueba32-01 : -n 1 D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster2\Prueba32-01 : -n 1 D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster3\Prueba32-01</EM></DIV>
<DIV> </DIV>
<DIV>Now the system is asking for user credentials. But when I enter "computer-name\User" and my windows account password, it didnīt accept it. </DIV>
<DIV>Do you know what credentials is this referring to? (Please see the attached image)</DIV>
<DIV> </DIV>
<DIV> </DIV>Horacio.
<DIV> </DIV>
<DIV>PS: I asume if I add <EM>\Program Files\MPICH2\bin\</EM> to my path environmental variable this should work without need to go to this directory to run the mpiexec.</DIV>

I have already suscribed to it.<BR> <BR>I have a code paralellized that is runnig OK when I compile it using Win32 Intel <BR><BR>Fortran compiler and MPICH1 libraries.<BR>When I compile it using EMT64 Intel Fortran compiler and MPICH2 libraries it is <BR>compiled OK but I canīt make it run.<BR> <BR>I need to run this on a single Windows 7 machine using its four cores (Intel <BR>i7). Once the core is finished I will run it on a 20 node cluster. Now my <BR>problem is to run on a single machine. <BR><BR>When running the win32 MPICH1 compiled executable there is no problem at all. <BR>Iīm using four
different folders and executing four executables. The executables <BR><BR>are the same, but the information they use is readed from different folders. For <BR><BR>this, Iīm setting the enviromental varibles manually, and runing the executable <BR>"Prueba32-01.exe" on four cores as follows:<BR> <BR>file "mpi.bat" on folder \HORACIO\DOCTORADO\2-Corridas\MPI\Cluster:<BR> <BR> D:<BR> cd <BR>\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster <BR><BR><BR> <BR> set MPICH_JOBID=ns.123<BR> set MPICH_IPROC= 0<BR> set MPICH_NPROC=
