[Isocops] Moving to SwRI

[Nathan Schwadron]

Hi Roland

Thank you for sending this out. The list below is an excellent start on what will have to happen fairly quickly. This is precisely what we need to work so that we become more independent and well positioned for the SOC move.

I have a couple of questions regarding the plan, and then I'd like to start making a checklist of the things we need to do to make the transition.  It would be good to converge on the plan before the meeting next week.

Great!

The requirement is ops-only but the goal is full data reduction

No, not required, but certainly desired. I think it would be a great exercise to get this aspect also functioning as it would give Joe some sense of what would need to change if we have a paradigm change in ops.

I think trying to do this in the next two weeks is a great idea if we can swing it. However, there are no hard deadlines. We should have the ability to run things from SwRI prior to moving machines to UNH. That will make the move far more safe.

Joe is working this with Bill Mottley

> What is the hardware configuration at SwRI these days?  Was its infrastructure upgraded to the mirror system at BU when BU was changed?  A quick "mount" on swena reveals no RAID mounted.  Swena is at 129.162.237.195, sweb at 129.162.237.196, and there's a swoc at 128.197.73.227.

I suspect/know the answer is that SwRI machines have been seriously neglected. Joe has agreed to work on this with William and get things up and running. 


> Ken, please refer to the files ISOC_HW_config.txt and ISOC_HW_svn.pdf in /usr/local/ibex/sw/isoc/src/doc/Admin for an overview of the hardware at the time of its writing.  Changes to the configuration were made a year or so back, and these changes probably did not make it into this document, but it's a very good start.  We should probably look at putting it into texi format and including it in the ISOC manual.
