[mpich-discuss] Error while connecting to host

[Jayesh Krishna]

Hi,
 Can you send us a test program that fails (source code of your MPI program)? Please also include the mpiexec command (the complete command with arguments) used to launch your MPI job.

Regards,
Jayesh

I suppose I should have replied to the list rather than to Jayesh only:

This is what I am getting, everything seems to be working here with cpi.exe, but 

not with my script

C:\Program Files\MPICH2\examples>mpiexec -n 2 cpi.exe
Enter the number of intervals <0 quits> 4
pi is approximately 3.14....., Error is 0.005....
wall clock time 0.000034
Enter the number of intervals 

The error I am getting on my program, however is still there:


[01:780]..ERROR:Error while connecting to host, No connection could be made 
because the target machine actively refused it. (10061)
[01:780]..ERROR:Error while connecting to host, No connection could be made 
because the target machine actively refused it. (10061)
[01:780]..ERROR:Connect on sock (host=JONAS-LAPTOP 192.168.1.13 , port=2163) 
failed, exhaused all end points
SMPDU_Sock_post_connect failed.
[0] PMI_ConnectToHost failed: unable to post a connect to JONAS-LAPTOP 
192.168.1.13 :2163, error: Undefined dynamic error code
uPMI_ConnectToHost returning PMI_FAIL
[0] PMI_Init failed.

So test script runs normally, I do not know why I am getting this error here

Hi,
Can you run the sample MPI program, cpi.exe, provided with the MPICH2 
installation (mpiexec -n 2 c:\Progra~1\MPICH2\examples\cpi.exe)?
Please provide the complete mpiexec command and the output in your email.

Regards,
Jayesh

Dear all,

by risking to be very unpopular in this list I will ask a good old question: how 

to solve 


[01:2100]..ERROR:Error while connecting to host, No connection could be made 
because the target machine actively refused it. (10061)

problem? After reading all of the related emails on this list I realized that 
nobody really gave a definite answer how to fix this problem. My situation:

-administrator account
-Windows Firewall is off
-smpd -status returns smpd is runnign on Jonas-laptop
mpiexec -n 2 hostname returns jonas-laptop

everything seems to be operational, but when I try o run my job I get

[01:2100]..ERROR:Error while connecting to host, No connection could be made 
because the target machine actively refused it. (10061)
[01:2880]..ERROR:Error while connecting to host, No connection could be made 
because the target machine actively refused it. (10061)
[01:2100]..ERROR:Error while connecting to host, No connection could be made 
because the target machine actively refused it. (10061)
[01:2100]..ERROR:Connect on sock (host=JONAS-LAPTOP 192.168.1.13 , port=1472) 
failed, exhaused all end points
SMPDU_Sock_post_connect failed.

thanks

Jonas
