[mpich-discuss] MPICH over WAN

[Eugene N]

Hi

I a have a bunch of friends all round the town, whom i can
persuade(blackmail, threats, usual stuff) to donate me their cpu time . But
they all use different ISP, and into the bargain few have real IPs, most
connect through NAT and their external IP changes every day or even hour.

Is there a scenario wich will enable me to hook them machines up in to a
MPICh ring? Perhaps I should use a VPN (hamachi for instance) to emulate the
LAN?

I wont be able to utilise uni network any time soon becouse of all the red
tape. Right now it would be the only way for me to mitch up a cluster, i
really hope some guru will help me out with advice.

Thanks
Eugene
