[mpich-discuss] I wonder if my mpdboot is the causeofproblem...help me!

[Gra zeus]

ello Rajeev,
ahh sorry about last email, my OS on two machine are different
quadcore machine is 64bit and OS is "Linux myquadcore_machine 2.6.18-128.1.1.el5 #1 SMP Tue Feb 10 11:36:29 EST 2009 x86_64 x86_64 x86_64 GNU/Linux"

dual core is 32bit and IS is :: "Linux mydualcore_machine 2.6.18-128.1.6.el5PAE #1 SMP Wed Apr 1 07:24:39 EDT 2009 i686 i686 i386 GNU/Linux"
Are these the cause of my problem? Do i need to run my MPI with the same 32-bit machines? Are there any configurations i need to set , to make them work togather?
thank you very much,and sorry again about wrong OS info in my last email
regards,Gra

Are the CPUs identical on them? Is one 32-bit, the other 
64-bit?

      one of them is quad core and another one is dual core. 
        however, OS,account,my password,install path are all the same.
        I use this  configuration "./configure 
        --prefix=/opt/localhomes/myname/mpich2-install" in both 
        machines.

          What are the exact parameters you 
          passed to configure when building MPICH2? Are the two machines 
          identical?

                hello, 
                  

                  thx for answer yesterday.
                  I tested my code in one machine (with"mpiexec -n 2 
                  ./myprog"),everything work fine - my program can use 
                  MPI_Send,MPI_Recv without any problems.
                  

                  today, I setup mpich2 on two machines. Both machines can 
                  communicate with others, ssh are tested on both machines, mpd 
                  work, mpdringtest work.
                  

                  however,when i run my program that use MPI_Send and 
                  MPI_Recv,  MPI_Recv is blocked forever.
                  so i write new simple code to test MPI_Send,MPI_Recv like 
                  this
                  

                          int myrank;
                  
                          MPI_Status status;
                  MPI_Init( &argc, &argv 
                  );
                  MPI_Comm_rank( MPI_COMM_WORLD, 
                  &myrank );
                  if (myrank == 0) 
                  {
                  int senddata = 1;
                  MPI_Send(&senddata, 1, 
                  MPI_INT, 1, 0, MPI_COMM_WORLD);
                  }
                  else if (myrank == 1) 
                  {
                  int recvdata = 0;
                  MPI_Recv(&recvdata, 1, 
                  MPI_INT, 0, 0, MPI_COMM_WORLD, &status);
                  printf("received :%d:\n", 
                  recvdata);
                  }
                  MPI_Finalize();
                  

                  

                  i got this error

                  ////////////////////////////////////////////////////////////////
                  

                  I also tried example/cpi that come with install package 
                  -> result is the example program freezed, without any 
                  errors.(I assume it stopped at MPI_Bcast())
                  

                  Can anyone help me with this?
                  This code and my program can run smoothly when I use 1 
                  machine (with option ,  -n 2, -n 4 .... etc) but whenever 
                  I start mpdboot with 2 machines, mpi processes can't 
                  communicate with other mpi processes via 
                  MPI_Send,MPI_Recv.
                  

                  thx,
                  gra
