DINF-DTCI Message-Id: Mime-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Xref: ukc comp.parallel.pvm:8176 I have this network configuration: 1 PC Dual Pentium @ 300Mhz with Solaris86 v 2.7 1 Sun UltraSparc with Solaris v 2.6 I am trying to run a simple MPI program where each node display the ID of the processor. When i run the program in only one of the machines it works a)UltraSparc: mpirun -arch solaris -np 1 %a/test -mpiversion MPICH 1.1.1O of $Date: 1998/07/13 13:29:16$., ADI version 2.00 - transport ch_p4 Configured with procesador 0 b)DualPentium: mpirun -arch solaris86 -np 2 %a/test -mpiversion MPICH 1.1.1O of $Date: 1998/07/13 13:29:16$., ADI version 2.00 - transport ch_p4 Configured with -cc=gcc -arch=solaris86 -device=ch_p4 -comm=shared -prefix=/usr/local/MPI -nof77 procesador 0 MPICH 1.1.1O of $Date: 1998/07/13 13:29:16$., ADI version 2.00 - transport ch_p4 Configured with -cc=gcc -arch=solaris86 -device=ch_p4 -comm=shared -prefix=/usr/local/MPI -nof77 procesador 1 but when i try to run the program in both computers i get this error: a) UltraSparc as the main node: mpirun -arch solaris -np 1 -arch solaris86 -np 2 %a/test p0_16682: 1: p4_error: cannot do xdr sends: 0 rm_l_1_16313: p4_error: interrupt SIGINT: 2 rm_l_2_16316: p4_error: interrupt SIGINT: 2 p1_16312: p4_error: interrupt SIGINT: 2 p2_16315: p4_error: interrupt SIGINT: 2 b) DualPentium as the main node mpirun -arch solaris86 -np 2 -arch solaris -np 1 %a/test p0_16503: p4_error: cannot do xdr sends: 0 bm_list_16504: p4_error: interrupt SIGINT: 2 p2_16691: 1: p4_error: interrupt SIGINT: 2 p1_16507: p4_error: interrupt SIGINT: 2 rm_l_1_16508: p4_error: interrupt SIGINT: 2 does anybody knows whats going on here and how to fix it??
