Technical news and SETI@home daily stats for 21.03.2007.

[Rattledagger]

Regular backup outage today. Everything was normal except we bounced the replica database to change one buffer size setting and now nobody can connect to it - even to shut it down! Seems like we lost all our connection permission info somehow. From what we can tell it is still acting as a replica and making updates, but we can't access the data at all. We're stumped. Bob's looking into it.

On the plus side, we got all the pieces in place to move another function off kryten and onto bruno: file deletion. I just fired this off, and at first glance it seems faster. Time will tell if this is an improvement. Bruno is a faster machine in general, but kryten had a gigabit connection to the workunit file server, while due to lab infrastructure bruno can currently only have 100 Mbit. So we shall see. Hopefully queues will drain after we recover from the outage backlog.

Here's a fun one: Since the switchover to using Hurricane Electric as our main ISP I noticed lingering traffic on the campus router which served our Cogent link. We're talking as much as 1 Mbit/sec. Today while updating lab-wide DNS records I noticed shserver2 was still there. This was the DNS alias for our SETI@home classic data server. I removed this entry, and check out the dip in traffic:



So, well over a year since unplugging the classic data server, there are still enough SETI@home classic clients around the world trying to access a missing server to account for almost 1 Mbit/sec of traffic on UC Berkeley campus routers. Not sure how to exactly explain the shape of this graph (and why incoming = outgoing). The diurnal shape and hourly ridges look like scripts or cronjobs running on machines that haven't been checked in ages.

A lot of BOINC naysayers like to point out how many classic users "quit" last year after the big transition. But this graph adds some meat to my theory that a large chunk of the SETI@home classic users actually left the project many ages ago, and their old clients simply continued to run unattended. Mind you, this is 1 MBit/sec of traffic without actual workunit data being sent - just SYNs, basically. I think. Somebody break out a calculator and determine how many SETI@home classic clients this represents.

Appart for Anandtech's stats, it shows how much more/less than Anandtech.
Also shows based on Average Work Done how many days for Anandtech to overtake the team, or be overtaken by a team behind...

Thanks for the tech news & SETI@home daily stats Rattledagger! :beer:

 

[petrusbroder]

Thanks for the info and numbers, Rattledagger!

Just joined TeAm Anandtech with SETI.

I was able to find my old email address which I used to sign up to Seti Cllassic.

Hopefully, I was able to bring over the 6000+ units I had under classic.

Welcome to TA

I'm not sure what happens to classic points when you switch teams ,I know with BOINC 'old points' stay with the team when you leave.
With classic it would move with you ,but seeing as classic is dead I've no idea!

ref SETI news
lol ,I know Darkone had a handful of classic clients still running til the deadline & most likely beyond ,PCs at an old job which naturally he no longer has access to.

Welcome.

The "classic" wu's will only be shown as an information-message under BOINC, they'll not be counted amongst your total "Cobblestones", so switching teams will have no effect on the "classic" wu's.

Oh well... nothing like beginning again as a newbie.

 

[Assimilator1]

Don't worry ,we all had to with BOINC
