[mpich-discuss] Error while connecting to host

[染次 孝博]

Hi.

I am developing the manual start program. (WindowsXP sp3,
MPICH2-1.2.1p1, VisualStudio2008 sp1, C++)
Program is very simple as below.

************************
*int main(int argc, char* argv[])
*{
* int numprocs,myid,namelen,i;
* char processor_name[256];
*
* MPI_Init(&argc,&argv);
* MPI_Comm_size(MPI_COMM_WORLD,&numprocs);
* MPI_Comm_rank(MPI_COMM_WORLD,&myid);
* MPI_Get_processor_name(processor_name,&namelen);
*
* for (i=0 ; i<argc ; i++)
* {
* printf("arg%d:%s\n",i,argv[i]);
* }
* printf("numprocs:%d\n",numprocs);
* printf("myid:%d\n",myid);
* printf("processor name:%s\n",processor_name);
*
* MPI_Finalize();
* return 0;
*}
************************

The result of the program with "mpiexec -n 2 program.exe" is below.

*************************
*arg0:D:\temp\MPITest1\Debug\mpitest1.exe
*numprocs:2
*myid:1
*processor name:HOSTPC
*arg0:D:\temp\MPITest1\Debug\mpitest1.exe
*numprocs:2
*myid:0
*processor name:HOSTPC
*************************

Next, I tried to start of the two programs manually with one PC.
As shown in the manual "Debugging jobs by starting them manually" , it
set up as follows.
In Host window:
set PMI_ROOT_HOST=HOSTPC
set PMI_RANK=0
set PMI_ROOT_PORT=9222
set PMI_ROOT_LOCAL=1
set PMI_SIZE=2
set PMI_KVS=mpich2
In Sub window:
set PMI_ROOT_HOST=HOSTPC
set PMI_RANK=1
:
: same as Host

Then , I started this program with cmd "program.exe" in Host window &
Sub window.
As a result, the following errors occurred and it did not operate well.

[01:3156]..ERROR:Error while connecting to host,
Can not connected because refused target computer (10061)
[01:3156]..ERROR:Connect on sock

Please let me know solution.

-- Thank you.
