With 23.5 MB first application download, and 1.3 MB WUs dounload, the HPF2 is not dial-up friendly. May I suggest that "broadband connection" be clearly specified in the HFP2 project requirements.

I agree. I have suggested before that we add a section to the bottom of the page that lists expected download and upload requirements for a project.

Per a post by knreed HPF2 uses the same in-build (UPX?) compression for the WU downloads as Rosetta, where the origins of HPF are. Fortunately the application is one time, but as commented here it could be sized down dramatically.
----------------------------------------On a per hour crunch, HDC is worse, 5mb a pop. Added: Tried compressing with the best i know and not but a few % gain if zipped on these hi res image files. Seemingly there is UBX compression format as well, but Rosetta reports use of UPX

Fortunately the application is one time, but as commented here it could be sized down dramatically. On a per hour crunch, HDC is worse, 5mb a pop. looking at this linked thread, this application definitly needs to be compressed using UBX. Ten minutes work by wcg would make a huge difference to thousands of new participants. If HDC downloads are 5 MBytes per hour, I imagine a 24/7 dual core host would be downloading 7.2 GB per month, which would translate to 9 GB usage with overhead added. Some ISPs have pakages with 10 GB monthly download limits. I agree that broadband usage needs to be added to the requirements. I would not be a happy camper if I recieve an email from my ISP telling me that my monthly allowance will be shortly exceeded. [Edit 1 times, last edit by Former Member at Feb 19, 2007 1:03:14 PM] |

I am running dial-up here.
----------------------------------------FAAH probably has the smallest download/upload packages of any of the subprojects currently running here on WCG. Other BOINC projects have an even wider range of package sizes. I recently tried a couple of malaria control workunits. They took 2 hours to run on this fast computer, but only 4 seconds each to upload on dial-up. Going in the other direction, the climate simulation BOINC projects are even more dramatic. It may take several months to complete a workunit, but subchecks are sent in each day and points-to-date assigned.

Please see this news bulletin: Compressing files download by the BOINC client
----------------------------------------BOINC now does on the fly compression from server to the client from version 5.4 and up. Tests have shown some phenomenal improvements. Watch the HDC Mask and PGM files come across and be astound. The compression includes also any science programs being upgraded!

meshmesh, I'm sure WCG thanks you for the lauding..... the next step is activating the client to server compression of the results..... same as for downloading, >= BOINC 5.4 is required, preferably >= 5.8.15.

..... the next step is activating the client to server compression of the results..... Agree. On faah project, the WU download is about 195 KBytes uncompressed, which now would be much smaller after introduction of the new compression mechanism. However, the upload of the faah results can be up to 450 KBytes per WU (varies depending on the length of the wu). Would be great if client side result compression is implemented too. We can only wait and hope. [Edit 1 times, last edit by Former Member at Mar 3, 2007 7:30:41 PM] |

The 'wait' & 'hope' .... think knreed doesn't mind sharing this bit of exchange on Feb.23:
----------------------------------------Question: "Someone just bringing up bandwidth usage limitations over satellite. Will uploads also get compressed? Some are still in the 400-600kb range." Answer: "The BOINC 5.8 client has supported for built-in upload compression. I haven't had time to start testing it out yet to make sure that it works correctly and implement backend mechanisms to handle results where some are compressed and some are not."
