I'm curious as to what your remedies would be for the hard drive failures (co-related with the Anti-virus server). By the way, was it excessive or unnecessary scans (or some kind of ineffectiveness or inefficiencies) by the Anti-virus app that may have contributed to the said drive failures?

The hard drive failures were not "hard" failures, they were proactive decisions made by the SAN to mark the drives as bad because they were starting to show bad sectors. So basically the SAN preemptively decided to fail the drives before the disks went to a hard failure. The antivirus server keeps a fairly active database that is continually updating with virus definitions and client status so hence the higher IOPS. After some digging the WCG client IOPS is negligible. The only real usage that seemed to be meaningful was when a server was working on CEP2. The server working on CEP2 would create 12-18 IOPS which is still negligible, as a rule of thumb for a "loaded" virtual server is 50 IOPS
So in the end CEP2 has more IOPS than any other project, but as JmBoullier said "its peanuts" |

It's good to see these education projects implemented. Excellent work. I have ALWAYS thought the way to get future crunchers is thru the Education Systems, get kids used to seeing Boinc run and get Projects to WRITE ABOUT HOW BOINC HELPED THEM and VOILA thousands of new users!!! Some VERY few Projects DO write about how Boinc helped now, but I think you can count them on less than half the fingers of ONE HAND!!!   |

Hello Saint Marys School.
Thanks for responding. The only real usage that seemed to be meaningful was when a server was working on CEP2. The server working on CEP2 would create 12-18 IOPS which is still negligible, as a rule of thumb for a "loaded" virtual server is 50 IOPS. At the minimum of 12 IOPS, you are 'paying' a 12/50 or 24% penalty. At the max of 18 IOPS, 36% -- a percentage which I have difficulty calling as 'negligible' specially when one considers that all that is from a single app. I'm still curious though about what your investigation revealed as to what likely may have contributed the most to have the bad sectors to start showing up. Would it still be operations by the Anti-virus?So in the end CEP2 has more IOPS than any other project, but as JmBoullier said "its peanuts" -- snip from Saint Marys School [Jan 29, 2012 2:55:52 PM] post ; |

Alright so we have now given the students the ability to voluntarily install the grid.
I am really interested to see how many kids actually start running it of there own accord. If we do not see enough kids join voluntarily we will install it using group policy. I will keep everyone updated |

Good luck Saint Mary's - I, for one (and I'm sure that there'll be plenty more), wish you well in getting your students interested in science of this nature.

Just another update:
We participate in STEM week and did presentations on how the grid benefits humanity for all of the grade levels, and also followed up with a mass email to families of the school. We did a text survey in the middle and at the end of each presentation and the kids ~86% were excited about and wanted to join the grid, but few did of their own accord. Not sure why, because all they had to do was click a link in an email to do the install. ( I even created firewall rules that would guarantee faster internet access for clients running WCG, I REALLY though kids would run the installer then  )here is the link for the news release: http://www.sms.edu/news/detail.aspx?pageactio...nkID=1375&ModuleID=89 The children/families have not been as proactive at joining the grid as I would have hoped. We have it currently installed on 1/3 of our fleet of laptops/desktops. Instead of forcing a rollout to all machines I have decided when a student brings a laptop by to fix another issue, or a technician has to visit a desktop location the tech will install the grid. This policy goes into effect March 19 so we will see how well that works. It will not matter because around June/July we will be imaging all of our computers and they will all be joined by default.  Anyway just updating everyone on our status |

Hopefully, once they've seen as to how non-intrusive the software is, then they'll start to believe in the software and participate.
