Subject: Re: [OMPI users] Process doesn't exit on remote machine when using hostfile
From: Shiqing Fan (fan_at_[hidden])

Hi,

The hostfile seems working for me on my Windows XP machines, but it
should be the same on Windows 7. The problem you had looks to me more
like a synchronization problem. Could you send me your test program?

Regards,
Shiqing
