Interesting stuff, David. I'm not sure I'm convinced by the total at the foot of the GFLOPs/computer column. Doesn't that come out as something like "total CPU power available to the project if there was one computer of each type attached to the project, and it was running full time"?
"Total CPU power available" would be sum(nhosts*gflops), and comes out at about 1.4 PetaFlops for SETI. You could factor in on_frac and the other time metrics to get a total for CPU power available to BOINC, but I don't imagine it would be easy to get a measure of total power available to a single project. >________________________________ > From: David Anderson <[email protected]> >To: Jarod McClintock <[email protected]> >Cc: [email protected]; 'BOINC Developers Mailing List' ><[email protected]> >Sent: Tuesday, 6 May 2014, 7:36 >Subject: Re: [boinc_dev] [boinc_projects] top host CPU only search possible? > > >I added a page, html/user/cpu_list.php, >that shows peak CPU speed (based on benchmarks) for all CPU models >with at least 10 active hosts. >For example, for SETI@home: >http://setiathome.berkeley.edu/cpu_list.php > >Projects: upgrade your server code to get this. >If you want, just deploy cpu_list.php >and update your html/inc/util.inc. > >In principle, statistics sites should show this info; >if you run one, feel free to use the PHP code. > >Note: this data shows the peak FLOPS of computers, not chips. >So it's a bit misleading - Xeons aren't that much faster, >but computers with Xeons tend to have several of them. >I'll see if I can factor this out somehow. > >-- David > >On 05-May-2014 1:40 AM, Jarod McClintock wrote: >> Could the search be operated off of measured floating point speed or >> measured integer speed? >> >> Jarod >> -----Original Message----- >> From: boinc_projects [mailto:[email protected]] On >> Behalf Of David Anderson >> Sent: Monday, 5 May 2014 8:18 p.m. >> To: [email protected]; BOINC Developers Mailing List >> Subject: Re: [boinc_projects] top host CPU only search possible? >> >> A "fastest CPUs" list would be a nice feature. >> Unfortunately I can't see how to generate it efficiently from the info in >> the database; we don't track credit separately for CPUs and GPUs. >> Any ideas? >> -- David >> >> On 03-May-2014 9:53 PM, Jarod McClintock wrote: >>> Hi all, >>> >>> The way I understand the top host website search to work now is that >>> the host with the most credit goes to the top.
