[9fans] IWP9 this year?
Hello! Although I probably won't be able to go unless it's close (a.k.a. in the Baltimore / Washington DC area -- which actually isn't perhaps a bad idea?), the subject of an IWP9 has been brought up several times this year. I'd like to get the ball rolling on this, in case anybody is interested in setting it up or attending. I think the question at this point is, ``Who wants to organize it, and who will attend?'' I'm perfectly fine to organize the event, and I'm sure my office could more than accommodate any interested attendees. Just kind of curious what timeframes people would be interested in, and whether people would be able / willing to come. If not, some discussion on the when and where might not be a bad idea, anyway. Let me know! --Devon

Re: [9fans] IWP9 this year?
There were some ideas of skipping this year and making the next IWP9 in the beginning of the next year. End of the year is a difficult time for travel, the budgets for travel are depleted, or not if the fiscal year starts earlier than the calendar one, not defined well enough.

Ok, I hadn't seen that. Similarly, I'm in Columbia, MD, which is about 15 minutes from both BWI and Reagan Int'l airports (Dulles is a bit of a hike; perhaps more towards 40 minutes), and there are many Amtrak stations around. Home of Message Systems (where I work, though we don't do anything interesting with Plan 9 except listen to me proselytize it), and a short distance away from the ``Nation's best Crab'' (I think that's what Baltimore is calling it) and Capitol. i was thinking about 22-24 october 2009. there was some discussion of changing the format to include some workshop this year. i would like to do that, but it's not clear to me what the format should be. i would imagine the workshop would start a few days before the 22 with prep taking place throughout the summer. since many of the likely workshop participants are doing gsoc, perhaps the workshop can be some hands-on with the summer's work and we can expect papers from them, too as well as the usual suspects. :-) if we can agree on that, i'd enjoy doing it. I like that format; I was thinking it would be good to see some of these projects have presentations as well. Additionally, October is sufficiently far in the future that it should work out rather well. I could probably make it down to ATL; would probably only be a 3-or-so hour flight. If you need any help with planning / logistics, that's fine. If people would rather do it here, that's fine. If nobody needs me to do anything, that's fine too, just trying to get the ball rolling :) - erik --dho

[9fans] IWP9 Logistics Poll
I made a logistics poll form based on all the ideas presented thus far. It would be great if you guys could fill it in, there's like 6 questions and a comment field, so it should only take about 1 minute total. Just trying to get a brief and centralized overview of what everyone's personal situation looks like so I can either pass that information off to someone who can start planning if the consensus ends up being it shouldn't be here (MD), or start planning myself. http://206.71.190.158/~dho/iwp9pref.html Would be much obliged if everyone (interested or not) could take time to fill this out. Thanks! --dho

The fact that I'm not an english native speaker does not help and my wording may be rude. This was not intended to say that clusters have no usage or whatever. This would be ridiculous. And I do expect that solutions that are indeed hard to get right are still used and not chosen or thrown away depending on the mood. Simply that, precisely, specially in the open source, for somebody like me, who does not work in this area, but wants to have at least some rough ideas just to, if not write programs that can be used efficiently out of the box on such beasts, but at least try to avoid mistakes that make the program a nightmare to try to use such tools (or impact the design of the solutions, having to deal with spaghetti code), following what appears on the surface is disappointing, since it appears, disappears, and the hype around some solutions is not always a clear indicator about the real value, or emphasize something that is not the crux. In my area, the watershed computation on a grid (raster) for geographical informations is a heavy process stuff, and processing some huge data calls for solution both on the algorithmic side (including the implementation), and on the processing power. So even if I'm not a specialist, and don't plan to be (assuming I could understand the basics), I feel compelled to have at least some ideas about the problems. For this kind of stuff, the Plan 9 organization has given me at least some principles and some hard facts and tools: separate the representation (the terminal) from the processing. Remember that processing is about data that may not be served by the same instance of the OS, i.e. that the locking of data, ensured during processing is, on some OS and depending on the fileserver or filesystem, advisory. So perhaps think differently about rights and locking. And, no, this can not work in whatever environment or with whatever i filesystem and fileservers. And adding Plan 9 to POSIX, showing the differences is a great help in organizing the sources to, between guarantedd by C, and system dependant for example. After that, my only guidelines are that if some limited, calculus intensive sub-tasks can be made in parallel but the whole is interdependant, one can think about multiple threads sharing the same address space. But if I can design my data formats to allow independant processing of chunks (locality in geometrical stuff is rather obvious ; and finally sewing all the chunks together afterwards, even with some processing on the edges of the chunks), I can imagine processes (tasks) distributed among distinct CPUs. In this case, an OS can, too, launch the tasks on the same CPU with multiple cores. At the moment, I think more on multiple tasks, than threads. But that's vague. I know what to avoid doing, but I'm not sure that what I do is not to be added to the list of don't do that things. -- Thierry Laronde (Alceste) tlaronde +AT+ polynum +dot+ com http://www.kergis.com/ Key fingerprint = 0FF7 E906 FBAF FE95 FD89 250D 52B1 AE95 6006 F40C

I am willing to host here in Austin, TX -- we have a classroom that seats somewhere between 50-75 that I can use, although getting everybody through security can be a bit of a pain. Downside is that Austin doesn't tend to be an international hub, so its more of a pain to get to flight wise -- doesn't seem we have any lack of volunteers to host this year anyways, but I figured I'd put it out there for the future. -eric
Re: [9fans] IWP9 this year?
As I live near Atlanta, I wouldn't mind the Athens venue. Since I'm more-or-less local, I could pitch in to help with logistics. -joe On Fri, Apr 24, 2009 at 11:45 AM, blstu...@bellsouth.net wrote: What do people think about erik's timeframe versus potentially mid-January / early February / early March 2010?

Re: [9fans] IWP9 this year?
The good thing about atlanta: major international airport, minimizes traveling to the IWP9 locale. I think that should be a consideration for location. I am sure Greece was wonderful but it was pretty much impossible for me to get to the last IWP9. ron

[9fans] wrarenas
Is wrarenas (write venti arenas back to disk) really really slow or have I a hardware problem. reading 10 arenas took 30secs or so, writing them into a new venti (even with a bloom filter and DMA turned on) took about 36 hours. is this expected? -Steve

Re: [9fans] wrarenas
and, writing should take the same amount of time as reading. that is you can switch -if and -of and you should get the same results. it could be that you are seeking around all over the place. on modern hardware, if you are doing significant seeks between each write, you can get down below 1mb/s. i addressed this problem in the diskless fileserver paper. - erik
