cexec is a software for building ad-hoc clusters. To install cexec, you need to first build it (type make) then copy the executables into /usr/local/bin or someplace in your path. Youll probably want to copy the manual pages (*.1) someplace in your $MANPATH. Note that the cexec on-wire protocol is still evolving in incompatible ways; Its not wise to try and use the cluster tools across administrative domains. A cexec "cluster" consists of: - One or more applications - An announcement address. This can be a broadcast address, or a multicast address. It could also be a unicast address, but then that wouldnt allow for other servers. The default is probably fine for most people ( - this value should be stored in the $GROUP environment variable. - A bunch of general-purpose unix-like machines - A keypair that identifies applications, and mutually authenticates clients/servers To build a cexec cluster, you need to decide on your applications, announcement address, and have computers to run it. As an example, well build a cluster-enabled version of "oggenc". This example assumes youve already got oggenc installed, and you already got your machines together: 0. Build the keypair using "ckeygen" ckeygen distributed_ogg 1. Distribute the "distributed_ogg" key to all of your "worker machines" 2. Distribute the "" key to all of your "client machines" 3. Start the service on all your workers: cservice distributed_ogg oggenc -o- - 4. Start a logger service on any worker or client: crat 5. Encode something, cexec < input.wav > output.ogg You couldve used any application- not just "oggenc"- with this cluster. You could make this cluster as big as you want (with multicast tunnels) and cross as many networks as you want (with cproxy). When "cexec" starts up, it locates the "best" copy of cservice on the network. It does this by broadcasting announcements. One of the cservice machines will attempt to "connect back" to the cexec after a delay thats proportional to the systems load. The first machine to "reach back" and perform the various challenges regarding the keypair is the winner. At this point, cexec multiplexes the local file descriptors over the work-channel and cservice does the reverse on the other side. cservice uses pipes where possible, but will use socketpair() to emulate readwrite devices like terminals and sockets. When "cservice" is done, it sends its exit code back to "cexec". If "cexec" didnt like any part of the protocol exchange, it "complains". If everything went okay, it announces the exit code in the same way. These "alerts" are received by a "crat" running on the network. Whats New in This Release: - This release doesnt regenerate parity, which should help acquire loaded hosts (above runq length 10.0) faster..
