Jay, I'm happy to see progress on this.. I quite interested in understanding how much of the AG environment you can support with one a box system and how reliable it is. --Rick At 02:33 PM 3/15/2001 -0800, Jay Beavers wrote: >Just thought I'd let you know that I'm now running an Access Grid node >on a single ~$4500 computer (not counting displays, microphones, >cameras) successfully.

Re: [AG-TECH] mjpeg

Bob, I was just last week visiting to Larry Rowe's group at Berkeley and they have been making some good progress on mjpeg. I saw a pretty impressive demo running on Linux for both capture and decode.. Also at Argonne we have been prototyping mjpeg codecs integrated into vic.

Drag. I will put more than 5 minutes of research into this and get it right tomorrow... already found a good website at http://greenwichmeantime.com/ with all the answers.

Bridgeport Room Reservations / Time standards
by Don Morton 20 Mar '01

20 Mar '01

Hello, may I please reserve the Bridgeport Room for 2100-0200 UTC on the following Wednesdays: 28 March, 4 April, 11 April, 18 April, 2 May, 9 May, 30 May. This will be used by Arctic Region Supercomputing Centre and U. Montana Missoula (and others) for SC Global, AGN courses, etc. planning meetings. At this time, I'd like to make the humble recommendation that we start using UTC (also known as GMT or Zulu) as a common time reference for AGN activities. As a non-Easterner who deals with Alaska collaborators, I've found it quite confusing to figure out when rooms are available, having to convert between Eastern or Central time, Mountain time, and Alaska time. My guess is that once there are active international sites, this will become impossible (or, at the very least, quite error-prone). With a common UTC standard, everybody only needs to understand THEIR relation to the standard. For those of you in North America, if you're on Standard time, the conversion to UTC is EST: + 5 hours CST: + 6 hours MST: + 7 hours PST: + 8 hours AST: + 9 hours Once you go to Daylight Time, you subtract one from the above. So, considering that not everybody switches to daylight time, UTC becomes even more convenient - we all only need to know OUR relationship to the UTC standard. So, just to be stubborn, I think I'll continue to make my reservations in UTC, hoping I don't get kicked off the Access Grid :) An additional benefit is that when you fly to England or Portugal, you'll have a much easier time making these conversions :) Grazie, Don -- Don Morton http://www.cs.umt.edu/u/morton/ Department of Computer Science The University of Montana Missoula, MT 59812 | Voice (406) 243-4975 | Fax (406) 243-5139

Don, I will post your dates tomorrow with your UTC time and a transitional note of (i.e. 27 March 8pm - 28 March 3pm (am I even close here)) I hoped to deal with UTC when the software for an AG calendar was in place. I will work with AG techs here at ANL to get this in place on our current schedule/website.

Don, this is a very good idea.. UTC would help resolve confusion..

marty, we'd be happy to stand by and say hello on demand, given it was a time when we were around. just depends on the time period. let us know -gurcharan dartmouth college --- You wrote: 2. Arrange with some external sites to stand by and be ready to talk to us on demand. We've done this and know it can be rather boring waiting for the next tour group but there are one or two sites we've done this for so if turn about is fair play... ;-) --- end of quote ---
