well it looked like the beta for the new project went off relatively problem free. so hopefully Monday when the WCG people get back to work we can maybe see the new project launch and then lets hope they have the time to complete the port over to windows/mac

I had a few beta WUs ready to go this morning when I checked.

Was waiting for the windows version but thanks to this thread and some curiosity, I just returned my first CEP2 unit, courtesy of andLinux
---------------------------------------- In case it's of interest to anyone: Went fairly smoothly, thanks largely to comments here and some on the andLinux forum. Definitely best to install it for lots of memory and disk rather than having to resize as I did. Also seemed best to install the latest good linux boinc rather than the 6.2.something synaptic can find. I even got a couple of Linux beta wu's yesterday  My firewall appliance is griping, and I'm still arguing with its configuration to try to shut it up without turnng off all alarms, but that's minor for this temporary geeky project. Happy to keep crunching CEP2 this way at least until the windows version arrives. Kinda nice to have linux on this box, so easily. Yes it's a bit laggy, but fine as long as the host isn't being used for significant other work. Taking a core off the windows boinc config of course helped! Thanks for the various pointers everyone. Many edits: had probs changing gui rpc port on linux for both windows and linux monitoring. Fixed except that boincmgr connection on linux has to be made manually, I can't find a way to specify rpc port (or host) on the command line. Good enough for now though.

ggdh, thank you. I have raised the amount of disk space for BOINC on the laptop to 20 gig - I wanted to make sure there was no problem doing this. I will get to the other machines later. Can you tell me what kind of feedback you get when you are short on space? The error-message is like this: 05.08.2010 22:39:59|World Community Grid|Message from server: The Clean Energy Project - Phase 2 needs 1086.37MB more disk space. You currently have 961.63 MB available and it needs 2048.00 MB. Also, if not mis-reading ggdh, 10 GB shared between Ubuntu and BOINC data-directory wasn't enough, but it's maybe possible 10 GB is enough... Hmm, worse-case, each CEP2-wu will use 2 GB then running, so if you adds an extra GB for the application and so on, and 2 GB to pre-download new wu's, a single-core would max need 5 GB, a dual-core 7 GB, a quad-core 11 GB, a hexa-core 15 GB, and an 8-way 19 GB. Each wu-file is AFAIK negligible, so easily goes into the 1 GB, and you can cache-up multi-day. Only if you've got more than #cores partially-done wu's will you be in danger of exceeding these limits. In practice the disk-usage will likely be lower, how much lower I've no idea, so don't know if even the 8-way will nicely fit in an 10 GB-disk-size, or if you'll need more. I have 4 cep2 WUs running right now with my cpus set on 98% using 2.9Gb of disk space. Have 6 work spaces in use with multiple things going on each. No lag, even in photo editing. Not bad to run but the buggers are long and and the 17 to 18Mb upload is a trip. |

Those 17-18MB are beta WUs? I remember that in my case WUs were ~13MB each. Bad compression?

Beta WU's? No, this is production on Linux!.
----------------------------------------Asked knreed some week or so ago as to what would be the optimal transmission road and one of the things he said was that what you see as size in the transfer view is pre-compression. Either the modems do the compression or in the case of CEP2, the file is zipped for best result. I've taken my client off-line as there is a CEP2 job about to finish and will examine the slot to better correllate the ins-and-outs. Also, please note that the result file grows with the amount of time the task runs. When the big jobs come we'll be seeing lots more.... 20-80 MB http://www.worldcommunitygrid.org/help/viewTopic.do?shortName=minimumreq

I just moved the data directory on my old 4-way cruncher off of C: to give me more disk space ready for these WUs. Now can we get on with releasing the Windows version, please? |

When the big jobs come we'll be seeing lots more.... 20-80 MB http://www.worldcommunitygrid.org/help/viewTopic.do?shortName=minimumreq Well, it's exactly as described and may also explain the low upload speed... the modems wont be able to compress this further (suppose they know not to try compressing something that's already packed). The zip of the last result was 18.2MB and the raw content is 33.6MB for 45 result file components. It's not like some text where the indexer could get to 90% compression.. Try compressing an mp3 file and you'll know. Why zip/gzip and not other squeezers to get the extra percent... well on that I found that Linux does not have much beyond zip out of the box and not sure what WCG/BOINC can or may transmit as compression software... zip is rather generic on any OS these days. Veering off from the topic entirely, a quick search on Linux best zippers:http://blog.terzza.com/linux-compression-comp...-lzma-vs-zip-vs-compress/ showing barely a difference for the main contenders...here LMZA being the top performer, but in another it was 7Zip which I prefer also and it's 7z format.  PS, it was good to have been asleep as the last checkpoint for this task took nearly 5 hours after flying through the previous dozen in minutes each. And, it seems BOINC standard includes Gzip since version 5.8 http://boinc.berkeley.edu/trac/wiki/FileCompression ... well now we know.

I love those Beta WU's! To avoid any confusion in this CEP2 thread, - betas which have been distributed these last days have nothing to do with CEP2 - CEP2 WUs currently distributed to Linux devices are real production WUs, not beta WUs. |
