It's been a busy bunch of weeks of behind-the-scenes stuff. I'll catch up on at least a few things.

So the data center (where most of our servers are housed, along with most of the important servers on campus) had a big network migration over to a new infrastructure this past week. This was mostly to bring the center up to 10Gbe potential (and beyond), but being we are still constrained by various other bottlenecks (our own Hurricane Electric route, our various 1Gb NICs, our ability to create workunits, etc.) we're not going to see any change in our traffic levels. Anyway, it went according to plan for the most part, though the next day I had to do some cleanup to get all the servers rolling again.

Yes, the cricket traffic graphs have changed during the migration. Did any of you find the new one yet? I haven't actually looked - we have our own internal graphs so this isn't a pressing need - but I did ping campus just now about it. Oh - just as I was typing that last sentence campus responded saying they are still evaluating options for how to gather/present this information. Looks like changes are afoot.

There is a push to finish getting our SERENDIP VI technology installed at Green Bank Telescope. Maybe as soon as mid-June, though nothing is set in stone (until we buy our flights). So the whole team is a bit preoccupied with preparing for that. A GBT splitter is already in the works.

We're well beyond the annoying wave of science database hangups for now (that were plaguing us last month as I was trying to migrate a full table into new database spaces). Now we're back to plotting the next big thing (or several things) to clean up the database, make it faster, etc.. A mixture of removing redundant data and obtaining new server hardware. I know I've mentioned all this before. We do progress on this front but at glacial speeds due to incredible caution, lack of resources, and balancing priorities. For example one priority was an NSF proposal round that pretty much occupied me and Dan and several others for the entire past week.

The whole Astropulse database cleanup project continues. As predicted, it's taking a long time to merge/reload all the data into the temporary database (current prediction: it'll complete in early June). Meanwhile we're still using server marvin (as normal) to collect current results. Once the merge/reload completes (all fingers/toes crossed) we will stop the database on marvin for a few days - merge them both together, and reload it all back on marvin. Note: if any of this fails at any time, we won't lose any data (we just have to try again in a different manner). We also aren't constrained by any this - we are splitting/assimilating AP workunits as fast we can as during normal operations.

Thank you for the update ;)

Matt, thanks for the news.

Thanks for posting news. Have a good three day weekend.

If everthing's working, how about getting the science page back online? - or if that's too low priority, how about taking that page down altogether?

Hello, from Albany, CA!...

What's happening? I noticed that I have no tasks. I thought the database cleanup was over?

You are more likely to get answers to such questions in the Number Crunching Forum, specifically the current Panic Mode: Server Problems thread.
