How-to Seti@Home on Cloud Ubuntu CLI

I needed to test the performance of a bunch of cloud machines this weekend, and what better way to do that then by running up a whole load of Seti@Home instances.

I did this by following these steps:

  1. sudo apt-get update - Some cloud images were out of date and produced errors if this wasn't run before installing any software.
  2. sudo apt-get install boinc-client - Some Clouds had 12.04 which needed about 350MB of downloads, some had 11.10 which only needed about 250MB.
  3. sudo /etc/init.d/boinc-client restart - Not sure this was really required, but it was a nice check to see that it was installed correctly and would stop and start again.
  4. boinccmd --lookup_account http://setiathome.berkeley.edu email@address password - This returns the authentication code which you need for the next step.
  5. boinccmd --project_attach http://setiathome.berkeley.edu/ authentication_code - This attaches the client to the project. Use a different URL for a different project. This also assumes you have a project username which you used in the previous step.
  6. boinccmd --set_network_mode always - Allows transfers to happen any time. Not sure if this is persistent.
  7. boinccmd --set_run_mode always - Allows the client to run all the time. Again, not sure if persistent.
  8. boinccmd --get_state | more - Make sure that the project has been registered correctly, and that it is getting work-units and tasks.
  9. sudo apt-get dist-upgrade - Most cloud images seemed to have an out-of-date kernel and needed some other stuff after the large download earlier.
  10. sudo reboot - After all that patching, make sure the machines are clean. All the cloud images I was testing had persistent images, so no problems restarting them.
I now have 35 cloud instances of Seti@Home running in addition to my small local server. It was very apparent how much difference there was in each instances performance, with some virtual machines taking 3 time longer to set-up than others.

I've been using the remainder of the £50 credit I got for Infiniserv, and 3 beta instances on the HP cloud.

Have you guys had and differing experiences?

UK Government seeking bidders for 'G' cloud

Interesting article at The Register. The UK Govenment is seeking bidders to provide a cloud for us by public bodies. reg.cx/1Rpg

Transistion to Cloud Servers

I'm moving all my locally hosted content to cloud based servers. So far I have moved my email to Google Apps For Your Domain and I have created a new blog (no content yet) to replace this one.

The Gmail move went pretty well as all I had to do was update MX, SPF and some CNAME records. The only non-working part was the start page as Google seem to have dropped support for this. I had actually setup apps before this limitation was implied, and I can activate the start page but it just doesn't work. There are others who mention this and the work-round seems just to use a Google Sites page if you want this. In fact there's quite a complete template for sites, just for this. I don't really need it anyways.

The blog will move slower. I have moved it off to a smaller sevrer for now and I'm trying to find a way to export the posts from CommunityServer to Blogger. I may just have to use the smaller server to setup redirects to the new blog.
