The way to do this is to give focus to the vic thumbnail view, hit the number of columns you wish (like "7".) As bob mentions, there is an upper limit. This option is not available via the vic menus.

How to see "all" vic objects?
by Don Morton 23 Mar '01

23 Mar '01

Here's one of those questions that probably has an easy answer but... Today in the Access Grid Lobby, I fired up vic and was overwhelmed with the large number of video objects in it from the various sites. In short, even running at high resolution (1280 x whatever), I couldn't see "all" the video objects. I tried a quad tiling, which probably gets "most" of them, but there were some below the limits of my display that I seemed not to be able to get to at all, simply because I had no more room to expand the vic window vertically. How do others resolve this problem? It would be nice if one could "scroll" down, but that doesn't seem to be an option... I feel like an idiot, but I can't see how I'm supposed to view any of the video objects that lie below the vertical limits of my display.....

Beacon enhancement
by Marty Hoag 23 Mar '01

23 Mar '01

We were reminded again today that while the beacon is very good at giving an overall picture of multicast availability, it has some blind spots. The one we ran into was the fact that the beacon, once it is going, doesn't test joins. The group has mostly persistent sources and traffic which means that state is kept in all the various routers even if MSDP has failed. This morning we ran into this when the UKy porta-node wasn't getting Source Announcements out to Abilene. The beacon looked fine but those of us who had left the venue last night couldn't receive video from UKy because we couldn't get the source information. Since Don Morton has been touting UTC (Universal Coordinated Time in English - or did I transpose the letters?) it got me thinking. At first I thought maybe the beacons should pick the last octet of the group to use based on the UTC/GMT hour of the day. But then I realized we really could do this with two groups - specify an even group for even UTC hours and use an odd one for odd hours. That way the various beacons would have to join a new group each hour and that would force end-to-end tests of join/PIM register/SA propogration, etc. Maybe by convention the even group would be indicated in config and the beacon would simply add 1 for odd hours. I realize this would probably cause problems with unsynced hosts (but then Lisa might like it if people paid attention to that), get messy on the hour boundaries, and maybe make long term tracking somewhat confusing. But it would allow more constant data (I had once thought about every beacon stopping for 10 minutes each hour or something) and it would exercise join/PIM/MSDP stuff each hour. Marty

Supreeya, We have two wireless systems here. One is a handheld, the other is a clip-on lavaliere. Here are the specs for each. Both have worked extremely well, are pretty good on batteries, and produce excellent sound. These were purchased as kits that include everything you need to get going. Our only problem was the first 2 systems we got were on the same frequency. We sent one back to the vendor (Markertek), which they replaced with another on a different frequency. They operate side-by-side without any problems now. Handheld wireless ----------------- Shure LX24/58 complete system includes: LX2 handheld transmitter with SM58 mic LX4 receiver with dual antennas Lavaliere wireless ------------------ Shure LX14/83 complete system includes: LX1 lavaliere transmitter bodypack WL83A professional omnidirectional lav mic LX4 receiver with dual antennas Hope that helps! -- Jeff Ramacher (jeffr(a)mhpcc.edu) | (808) 879-5077, x264 Maui High Performance Computing Center (MHPCC) | fax (808) 879-5018 | http://www.mhpcc.edu > Supreeya Miller wrote: > > All, > > I need some advice. > > We are in a process to buy equipments for AccessGrid Node for the > ACCESS center at Stennis Space Center, MS.

Urgent: Probable Network Outage at ANL 3/23 @7PM -> 3/24 @ 5AM PST
by Nestor J. Zaluzec 22 Mar '01

22 Mar '01

Colleagues.... ANL is part of ESNet and this outage described below will affect many if not all of ANL's links to the outside world. Below is part of the message describing the problem if your interested. Nestor ================================================= From: "James F. Leighton" <jfl(a)es.net> Subject: URGENT: Major Qwest/ESnet outage Mime-Version: 1.0 X-Mailing-List: <essc(a)es.net> X-Loop: essc(a)es.net Precedence: list Status: This message is to give you the earliest notice possible of a planned total outage of the Qwest 550 ATM backbone, upon which ESnet rides. The outage is planned to start at 7PM PST, tomorrow, 23 Mar, and conclude within 10 hours. IT WILL TAKE DOWN ESSENTIALLY ALL OF ESNET DURING THAT TIME!! The driving event is an error in the Lucent ATM switches that Qwest is using to supply services to ESnet. This "bug" causes an event called a cascading re-route, whereby all of the PVCs (virtual connections) in the ATM backbone are re-routed caused massive changes in latency and packet loss. We have been hit with this event several times, the most recent was twice this last week-end. The scheduled downtime is to be used to reload all of the high-end 550 Lucent ATM switches with new code. The procedure advised by Lucent is to take all the switches off-line during this reload, estimated to take 10 hours. Clearly we (ESnet) are very unhappy about this and have pushed for a less ugly solution or at least more notice - i.e. delay the outage. Qwest claims they have no options and must move forward - they have deployed people on airplanes, coordinated schedules, shipped parts, notified other customers, etc. I was just notified about this late yesterday afternoon and had hoped to push for a better solution, but was unable to do so in this morning's conference call. So I am sending this notice based on what I know at the moment. I anticipate this may have serious implications for some sites, so would ask the ESnet Site Coordinators to forward this information as quickly as possible to allow people to undertake whatever advance preparations they can. Needless to say I am extremely unhappy about this situation, but at this point I think our choice is a scheduled (with very short notice) outage, or face the likelihood of an unscheduled outage with no advance notice, and without the resources available that this event will have. As soon as we are able to do further planning, I will keep you up-to-date with and additional pertinent information. JFL =========================================== Dr. Nestor J.
