RE: [AG-TECH] Hardware news - towards a single machine node
Ivan attached are specs on how to put together a passive stereo display driven by a PC and a dual channel GeForce2 (AGAVE- Access Grid Augmented Virtual Environment). So far the sites that are building them are USGS, Access, NWU, U Michigan Geology. Using the CAVElib you can drive it in either Windows or Linux. We are also bundling the software as part of the AG CDROM.

Hey all,
I'll be working in the next few weeks on a written definition of AG Node Requirements. This will mostly be formalizing alot of the information we already have. This will shake out what it is we expect the current 4 machine node to do. Defining what this functionality is, and building the API's for each component will let us explore this kind of idea without impacting the current operating schedule of the AG (ie, we're way too successful to have people randomly breaking nodes for experiments).
One part of this is to define "Core Node Functionality" and "Auxillary Node Functionality". This is the line between what a minimum node is (the Core Functionality) and what a cool far out node might include (microscopes, milling machines, mood indicators, whatever). If you have ideas for what you might augment a node with, please send those to me so I can include them as examples...
Any thoughts? Ideas? Are you going to toss me off the ship yet?

PS -- Oh my, we might actually start version numbering!

I think it would be really cool (but probably way too expensive to develop) to move some of the AV processing off of the system CPU to a special purpose AG pci board or something like that. Does anyone know if there's a "vic in a chip" kind of thing already?
Just my thoughts on a Friday afternoon... -- jeffr

Given discussions regarding CPU requirements for a single
machine node,
thought you might like to know I saw a pre-production dual P4 (1.7GHz Foster) from Dell today: 64 & 32 bit PCI buses, built-in 1394, onboard fast Ethernet. The real news is that they expect to start shipping these in May with a reasonable starting configuration under $4K. Needless to say, 4 cameras and all those video streams are not going to be an issue.
We also had discussions with Viewcast/Osprey about getting P4-optimized drivers for their capture cards and we're following up separately with their development team next week. It would still be nice to get all of this running on a single proc P4 to keep the cost down even further.
