</HEAD><BODY>Hi,<br><br>I can't run MPI program on xeon and itanium clusters mpich2-1.2.1p1 .<br><br>Im testing like this:<br>mpiexec -configfile myconfig<br><br>and myconfig:<br>-host x3 -np 1 program.x86_64<br>-host it4 -np 1 program.ia64<br><br>when program.x86_64 and program.ia64 dont use MPI everything works ok<br>but when they are MPI programs I get:<br><br>[cli_0]: got unexpected response to put :cmd=unparseable_msg rc=-1<br>:<br>[cli_0]: aborting job:<br>Fatal error in MPI_Init: Other MPI error, error stack:<br>MPIR_Init_thread(283): Initialization failed<br>MPIDD_Init(98).......: channel initialization failed<br>MPIDI_CH3_Init(176)..: generic failure with errno = 336068751<br>(unknown)(): Other MPI error<br>rank 0 in job 45 gondor_48526 caused collective abort of all ranks<br> exit status of rank 0: killed by signal 9<br><br>I have also tried mpich2-1.3a2 with hydra process manager<br>and "mpiexec -configfile myconfig" runs ok with MPI but without heterogeneity (both program compiled for the same arch)<br><br>Is it possible to run heterogenous programs with hydra or how can I run MPMD MPI program<br>on mpich2-1.2.1p1?<br><br>Regards,<br>Adam<br></BODY></HTML>
