	Access to files etc is solved by MPI where things are copied across nodes and everything is unified. My approach was more coarsely-grained one, where instead of looking how to parallelise Csound internally, I would build a host that would run parallel instances of Csound and then load distribution would be a matter of starting events on each of the nodes. One instance would distribute inputs (if any) and collect the outputs, possibly in a blocking way, but asynchronous operation also was something to try. Eventually we would move towards a software that would load-balance automatically. Of course, not many problems are coarsely-grained enough for this type of approach. So, perhaps we are not talking about a generic cluster solution, but one tailored to a particular system, but working from the API level, rather than providing support inside Csound. This does not exclude a possible SMP version of Csound that runs parallelised without the user having to do anything in particular. But that is a different thing altogether.

	And going even more coarse grain - does anyone know of a sample- accurate mixer that accepts audio stream buffers from across a network. With a pause-until samples-arrive would be even nicer.

	For OLPC Barry Vercoe and Simon Schampijer added new opcodes to Csound5 The midiremote family. - insremot insglobal midremot and midglobal You see that you assign unique IP addresses for the master and the receivers (ultimately the XO's will learn these and publish these on their own as part of the MESH network) and you can layer instruments - etc... These allowed us to have Csound run on a master OLPC XO machine and send the score remotely to 4-6 other XO computers. We had version of some nice pop songs made with soundfonts and MIDI (by my Berklee students) and some 4-voice bach fugues, and trapped (of course) all divided up and performing on these multiple machine wirelessly - the sync was pretty good. Simon can really tell you more of the details of the system and the issues that we faced. I did the composing and orchestration and make the orchestras work. Essentially each machine had a complete copy of the orchestra and score and the master computer used the midiremote message to assign which voices would be rendered by which XO and also served as the master clock. Barry did attempt to play some longer sample-based works by his son Scotty. These had huge audio tracks of drums and backing vocals - and in these, the sync was much worse, but our note-list and midi examples using soundfonts were pretty cool and impressive - In Vegas, when we introduced the XOs - we did a multiXO version of Trapped in a HUGE theatre - it was pretty great. Here are several of our demo orchestras.

Subject	[Csnd] Re: parallel rendering, eg via clusters
	For OLPCsound - Barry Vercoe and Simon Schampijer added new opcodes to Csound5 The midiremote family. - insremot, insglobal, midremot and midglobal Ii think that they are in the manual? In my XO demo .csd files below, you can see that you assign unique IP addresses for the master and the receivers and you can layer instruments - etc... (ultimately the XO's will learn these and publish these on their own as part of the MESH network) These allowed us to have Csound run on a master OLPC XO machine and send the score remotely to 4-6 other XO computers. We had version of some nice pop songs made with soundfonts and MIDI (by my Berklee students) and some 4-voice bach fugues, and trapped (of course) all divided up and performing on these multiple machine wirelessly - the sync was pretty good. Simon can really tell you more of the details of the system and the issues that we faced. I did the composing and orchestration and make the orchestras work. Essentially each machine had a complete copy of the orchestra and score and the master computer used the midiremote message to assign which voices would be rendered by which XO and also served as the master clock. Barry did attempt to play some longer sample-based works by his son Scotty. These had huge audio tracks of drums and backing vocals - and in these, the sync was much worse, but our note-list and midi examples using soundfonts were pretty cool and impressive - In Vegas, when we introduced the XOs - we did a multiXO version of Trapped in a HUGE theatre - it was pretty great. Here are several of our demo orchestras.
