Can't launch parallel program on Windows 7 Home Premium SP1 x64

Can't launch parallel program on Windows 7 Home Premium SP1 x64

Hi:
I have 2 machines, and both of them are installed with Windows 7 Home Premium SP1 x64 version.Machine1: 192.168.1.65Machine2: 192.168.1.73Both machines installed the smpd from Intel MPI 4.0.2.004mpiexec.exe is also from Intel MPI 4.0.2.004Both machines set the autodisconnect value to zero(According to the release note of Intel MPI:Some operating systems have a limitation on the number of concurrent connections. This limitation may cause job failure with the following error message:"no more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept".

To reduce the probability of this issue, decrease the auto disconnect time.

From the command line do the following:

net config server /autodisconnect:time_before_autodisconnect

The default value of the auto disconnect time is usually set to 15 minutes.)The parallel program is just a hello world program.I run the following command:mpiexec -hosts 2 192.168.1.65 8 192.168.1.73 8 \\\\\\\\192.168.1.65\\\\Shared\\\\HelloWorld.exeAnd I got the following errors ...

But sometimes (only 10%) the HelloWorld.exe are launched successfully.

Is there anything for tuning in Windows 7 ?

Please help, thanks very much!
