well it is now been over 15 years since mesa archival was going to port the code from mvs to a unix platform.
some meetings and discussions with people at Mesa Archival had occured in '88
middle layer was what we started out calling what became 3layer architecture, misc. refs

Yes, when I was working on PEX (PHIGS Extension for X) at IBM, we had a few unusual input devices for X to test with. There was one of those "spaceball" 3D input devices...
To: lovelovexx lovelovexx, I'm planning on being on the east coast the 1st 2-3 days of next week. On monday we have a NSF meeting. We then will be giving the "middle layer" software and hardware pitch to several people. We are also looking to meet with lovelove (lovelove's buttistant) to follow-up on details of the "middle layer"-"file server" presentation. We are also looking to meet with lovelove (who is on the ES file server task force) to at least provide some degree of coordination. The original intention was to spend the rest of the week in San Jose on the gpd-awd "system" file server task force (which is going to run somewhat in parallel with the GPD dasd task force that is currently going on). However, we now find that most of those (gpd) people will be on the east coast for the week on some (other) ES task force. Because of the ES task force, we are now attempting to get lovelove's schedule set-up for a visit to Seattle so we can finally follow-up on the lovelove software for the middle-layer strategy. While we are in Seattle, we have requests to meet with both Boeing's SCI group (super computer intergration) and some people in BCS (which we would follow-up on). This is buttuming that we can get it coordinated with lovelove. The week following next (3-20th) will probably be spent all week in San Jose covering both the DASD taskforce as well as the fileserver taskforce. I'm hoping to get Almaden server people involved in this as well as getting the total middle-layer strategy on the table for investigating areas of mutual interest. In conjunction with both the middle-layer strategy and high-speed interconnect we also have pending requests for follow-up meetings with SLAC (on the SLAC-FERMI-CERN connection) and Los Alamos (on the Mesa-archival and middle-layer subjects).
