G'day Mike I think you have asked a good question here and I thought I would voice my opinion to why I think there hasn't been any Room based nodes using MAC's to date.
As you may or may not been aware, the Access Grids have been around for a number for years and I personally have been playing with them for nearly 4 years. In this time, the Access Grid software (mainly the media tools) has only worked on either Linux/Unix or windows. It has only been recently that a full deployment of the Access Grid software has been fully supported for the Mac. I currently have an iMac which I have AG 2.4 and 3.0 Beta1 running on it, in which I use the iSight for the video capture. In my opinion, the older versions have been a little buggy and it wasn't until the release of AGTK 2.4 that it became stable enough to use on a regular basis. The biggest thing I have noticed with the Mac version compared to the Windows and the Linux version have been the "Sluggishness" and having it running what appears to be a lot slower (and tends to use a lot of CPU). Upon using the AGTK 3.0 Beta1, it looks a lot more promising and "appears" to run a lot faster as well. Given I have only ever used the AGTK on a single "Mac" node, I am unsure if the following problems may also limit the building of an AG Room Node. So things to consider that I hope others might be able to comment on are whether: * the Mac has driver support for multiple capture cards; * the Mac can support multiple screen/projector display. (I am pretty sure it can, it's just I have never done it nor can I recommend what video cards to use) Other than the above two points, I cannot see why someone cannot build a Room base node using Mac's. I would be interested to hear if you are able to do it. Hope this helps, Cheers, Jason. -----Original Message----- From: owner-ag-t...@mcs.anl.gov [mailto:owner-ag-t...@mcs.anl.gov] On Behalf Of Mike Bogle Sent: Wednesday, 15 February 2006 3:19 PM To: ag-t...@mcs.anl.gov Subject: [AG-TECH] Creating an AG Room Node using a Mac Backbone? Hi Everybody, I have been asked to research the logistics of implementing an Access Grid Room Node at our university, and I am hoping that some of you might be able to help me resolve a question. Specifically, I have been told by our IT Manager that Mac's would be the preferred operating system for the backbone of our uni's room node. However I have been so far unable to locate much of any information on either the Access Grid homepage (http://www.accessgrid.org/), or community pages such as AGCentral, that would help shed some light on this topic. For example, a quick browse of the Global Nodes in our country (Australia) seems to indicate that most Room Nodes are founded on either a Windows or Linux backbone. Is this the case? And if so, why? I would also be particularly interested in hearing from other institutions and/or organisations who have either run into difficulties establishing room nodes using Mac backbones, or who have succeeded and are using them currently. Any and all help would be appreciated. Kind regards, Mike Bogle
