Is it a single large dir (surely not), or how do the dependencies work? No, there were nearly a hundred directories scattered all over the place. It was actually quite a mess. There were also a couple of hand-enforced relationships that were quite messy. The entire mass was big enough that parallelizing was hugely beneficial even with the ugly mess the build system was. For instance, with ACE/TAO (many hours to build when including orbsvcs) there's only a few large directories that can be parallelized over say 10 cpus by gmake, at least. These are the types of directories that can benefit easily. Ideally, with no overhead for job starting, you would be able to use n processors to compile n files all at the same time. Realistically you're quite limited by the network bandwidth and the speed of the file server, but since compiling is not a completely I/O bound process, you can do perhaps some- what better than just an obvious bandwidth multipler. For instance, if you have 100BaseTX on the build machines and 1000Base?? on the file server, you make actually be able to utilize 12 or 14 or maybe even 20 build machines before saturating the fileserver. The rest have ten files or less where each file takes maybe 45s to compile on a 1GHz processor. There are quite a few of these. And directories are compiled sequentially. If you replace your recursive Makefiles with a single dependency tree, it doesn't matter how many files are in a directory. You can launch enough compiles to complete the directory, building the executable or library or whatever is made there, because you can be sure that all if it's dependencies have already been built, and that nothing that depends on it will get touched until it has completed. There is a good discussion of this on the Perforce web pages, in their discussion of Jam/MR, a somewhat newer tool similar to Make. Jamfiles are never recursive; tools are provided for building Jamfiles that describe the entire project so the dependency tree is completely expressed. % Nowadays, you'd want to "globus ify" things, rather than % use use PVM. % % But critically, speedup would only happen if jobs were % allocated at a higher level than they are now. % % Now for building something like a full version of TAO, % why that might work.

For some reason the Open Source community still has this bizare idea that PVM is the way to go. MPI is way to heavy for process spawning. We have measured appallingly long times here on our clusters, up to 30 seconds just to get things running on 64 nodes. I keep offering this, and keep getting no takers, but I do have a tool called vex that will get 128 processes running on 128 nodes in 1/2 second. See it at http://www.lanl.gov/~rminnich/. That's the level of performance you want for a start. It actually runs tons better on FreeBSD than on Linux due to Linux TCP silliness. You really want a single login, single IP address, cluster. There's an example: http://www.scyld.com. You need a process model that's much more capable than what we have now. Three ways to go that I can think of. The worst is to nfs-mount all the /proc on the front-end. Yuck. The second-coolest-thing to do is to build a "bproc"-like interface for freebsd. The absolute coolest thing is (do I repeat myself :-) put plan-9 style remote process and private name spaces into freebsd. Before you comment on the plan9 idea, if you have not read the docs, go read them. Bproc gives you a global name space for processes, which is ok but not as scalable as the plan9 approach. But the Scyld stuff is quite nice, we're using it here on two clusters. ron To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

RE: Clustering FreeBSD
The first question I have when someone brings this up is, "please define what you mean by clustering". There are multiple interpretations.

Re: Clustering FreeBSD
In all honesty, I am just looking for something to play with and see how fast FreeBSD can go. Sort of thing where those two guys clustered about 200 486's or something stupid like that.. :) Jamie On 2001.01.16 18:31:43 + [EMAIL PROTECTED] wrote: On 16 Jan, Jamie Heckford wrote: Hi, Does anyone have any details of Open Source, or software included with FreeBSD that allows the clustering of FreeBSD?

Install the pvm port (ports/net/pvm) on the machines. I've played around with this a bit, and it's quite fun to watch. Check out the X11 fractal demo ("xep"). There's also a port of povray (ports/graphics/pvmpov) which uses PVM to distribute it's processing.

I've admined one such cluster. The stuff is all in the ports. And Beowulf is free, open source. Try PVM and MPICH. However, the real question here is: What do you want to do? Clustering does not really help a lot of things.
