[MPICH] communication between linux and windows

[Jayesh Krishna]

Hi,
    The error message says that host name resolution failed for one of the hostnames specified. Try specifying ip addresses of the machines on which you want to run your program. Please try running the mpiexec command on both the machines and let us know the results (Provide us with the command and the complete output).
    If the error persists please provide us a detailed information on the systems (which node is linux and which is windows, where are you running the mpiexec command ? etc) you are running your program. Also please try running the sample program (cpi.exe) that is provided with the MPICH2 installation (Windows).
 
Regards,
Jayesh

Subject: [MPICH] communication between linux and windows


Hello，everyone .
Now I puzzled about the processes running on both linux and windows(mpich2).
Firstly ,I used two machines for the test (one windowsXP,one fedora3 ).The windows saves as root.
And then ,and running the smpd on both two machines.
When I input the command as follow for test
mpiexec -host ***.***.**.1 -n 6 hostname : -host ***.***.**. 2 -n 6 “/bin/hostname”
the command was executed;
but when I was running a small programme like “hello world”
 
there were errors below:（launch 4 processes totally）
 
Hello world from process 0 of 4
Hello world from process 1 of 4
 
 
 
job aborted
error message:fatal error in MPI_Finalize: other MPI error,error stack:

MPI_Finalize(154)............:

MPIDU_Sock_post_connect(1228).......:unable to connect to amon on port 3284
MPIDU_Sock_post_connect(1244).......:gethostbyname faild
 
 
I have turned off the firewall completely,and the programme uses the code which is the example in the package of mpich2.
 
Any help ??
Thanks and Regards
