e-science, the grid, and supercomputers
Having recently been made aware that my university is moving in a very major way into the field of e-science by bringing online a new supercomputer and intending to hook that up to the national lambdarail project as part of the terascale grid computing network, I'm wondering if anyone on the list is working on any of these topics, as they all have to do with internet research in some way, and specifically scientific uses of the internet, well at least in our case. here are some informational links: lambdarail http://www.getlight.net/ Virginia Tech terascale cluster http://computing.vt.edu/research_computing/terascale/ Jeremy Hunsinger Center for Digital Discourse and Culture () ascii ribbon campaign - against html mail /\ - against microsoft attachments

Our university (Indiana U) is pretty heavily invested in grid research, and becoming more so. Computer Science was awarded several fairly weighty grants in the last couple of weeks, so I expect the investment will escalate .... I'm not convinced that "grid computing" is anything more than a word that people toss off to describe a set of paradigmatic assumptions - i've heard it used in several radically different ways by people doing computational work in different source domains. elijah
Over on Tribe.net, the head of this area at IBM gave me these urls in response to my enquiry about the grid http://www.ibm.com/grid http:// www.gridforum.org http:// www.gridcomputingplanet.com and http:// http://www.teragrid.org/about/index.html others might find them useful to explore some of the research and projects underway

I'm not sure either, but I think there are possibilities of categorical difference when you start talking about terascale grids. The raw computational power starts to sound like the computers in greg egan novels.

To add to this (and to provide context to Steve Woolgar's request) here is how the UK's Social Science Research Council construes the relationship between of 'e' and 'social science'. http://www.esrc.ac.uk/esrccontent/researchfunding/escience.asp And more specifically: http://www.esrc.ac.uk/esrccontent/researchfunding/esciencespec.asp There was a useful discussion led by Steve at the OII/iCS conference already mentioned over whether this stuff is a paradigm shift or just more of the same but faster/bigger/whatever.

A big part of what we do at UIC's Electronic Visualization Lab (EVL) working with the AccessGrid (http://www.evl.uic.edu/accessgrid/) and working on the OptIPuter project (see http://www.evl.uic.edu/research/res_results.php3?cat=6). An area of study in both cases (and others involving high speed networking) is collaboration over high speed networks.. Sj At 2:35 PM -0500 9/25/03, elijah wright wrote:

Dear Air-er's - I recall a lot of hype around internet2. But the latest review I saw of its implementation (in a recent Chronicle of Higher Ed, don't have the exact date) looked very under-whelming. It was a new bandwidth and was supposed to offer broad spectrum high speed connectivity, especially for 'internet video' - a friend of mine was worked at Southern Cross Uni on the video implmentation for distance music teachers/pupils in Australia, another team (I believe at U-Kentucky) has worked on a similar project and not had much joy on the inter2 network. Despite the vaunted specs, it is too slow for interactive music instruction via 'webcam'. Ok, doesn't grid sound like inter2 all over again? Anyone out there working on project implementation with an inter2 link that is going well?? and I have continually heard that IPv6 is coming. Has it arrived in the US or anywhere else for that matter? Having a skeptical moment, Denise ===== "The distance between here and there is growing; and getting even larger as we speak" (S. S.

Oh, I don't know.... while I'm not a big I2 guru, our Music Department is in its second year teaching hand drumming between here and the southeast coast via I2. . . there's a tiny lag, but the musicians worked it out... On Saturday, September 27, 2003, at 09:59 PM, Denise N. Rall wrote:

One of the problems with I2 is that it became a production network, much of the traffic that I originate passes at some point in time over the i2 network, and it is the same with many other universities, i2 is no longer 'experiemental' however, i think the difference between the grid and i2 is that the grid is aimed at creating a new computing infrastructure as much as creating a new networking infrastructure. as for ipv6, yes, it is alive and working, most of i2 is v6, however, most people will never know and fewer people will be able to take advantage of ipv6 because the technical barriers, issues, etc. are managed at a higher level than the user, usually at the peer provider level. so i don't expect to see people learning to enter their ipv6 ip-name any time soon...... it is far easier to assign users ipv4 names virtually then wrap their packets in v6 up the line. one of my current major question in regards to grid computing is the 'for whom' a terascale network for research for whom? I have been reading all the responses on this though, and there are quite a few interesting projects occurring now, I suspect that these questions will be dealt with more closely at 4s this year, but I have to be at AoIR, next year though I'm hoping to make both.

"grid" computing is being pushed as mostly cell-based - for ex, pods of nodes with gigabit links between them, seperated by slower 10mbit or 100mbit lines - while I2-style research was characterized by its focus on massive bandwidth consumption without much regard for the computation happening at the peripheries. so, paradigm 0: "gosh this network is slow..." paradigm 1 (I2): "we need more bandwidth, we'll figure out what to do with it later..." paradigm 2 (grid-ish): "golly, now that we have a lot more bandwidth, it sure would help to be able to generate computationally intensive problems that take advantage of that... whether they require massive data transfer or just massive amounts of intercommunication...." elijah

Dear Isidro, I have been carrying out myself some logfile analyses. The most recent one is for a large public utilities operator. The data for the accesses to content pages showed about 18 million requests for 30 days, but when I filtered out spiders I was left with some 15 million and 500 thousands page requests. Should you need more details and/or assistance in dealing with your logfile please do not hesitate to contact me directly.
