A method performed by a system comprising a processor and a memory can include performing a global placement of a circuit design for a target programmable integrated circuit (IC) and clustering the circuit design using a selected size of cluster regions according to control sets identified within the circuit design. The method further can include determining a legalized placement of the clustered circuit design by solving a minimum cost network flow problem for the selected size of the cluster regions and the target programmable IC and assigning components to sites of the target programmable IC according to the legalized placement. The circuit design specifying the legalized placement can be stored within the memory.

A distributed collaborative computer system is provided that comprises a plurality of server computers interconnected via a high-speed link. Client computers can connect to any available server computer and start or join a conference hosted on either the server computer to which the client computer is connected or any other server in the system. As a result, the system and method of the present invention is easily scalable to support an arbitrary number of participants to a conference by merely adding the appropriate number of server computers to the system. In addition, by replicating the conference information on more than one server computer, the single point of failure limitation is eliminated. In fact, if a server hosting or participating in a conference malfunctions, the failure is detected by other server computers and the client computer is able to reconnect to the conference through a new server computer.
