21) Message boards : Number crunching : Did you build for boinc only? (Message 61458) Posted 30 May 2009 by nick n Post: Well I don't have a core i7 yet but I can tell you they are pretty expensive still. Just the i7 920 CPU and motherboard cost $529 from tigerdirect and then you would need everything else too so from my estimates a well equipped machine would cost around $1000. Also I wouldn't recommend the 965 since just the CPU alone costs $999 and all of the I7's have an unlocked multiplier anyways.

23) Message boards : Number crunching : Once upon a time, Rosetta Betta 5.98 crunched w/o errors... (Message 61239) Posted 17 May 2009 by nick n Post: weird... It is the complete opposite for me though. Every single 1.67 fails and all of the 5.98s run great. Is that windows 7 your running there too?
24) Message boards : Number crunching : Problems with Minirosetta Version 1.67 (Message 61218) Posted 16 May 2009 by nick n Post: After an update to Boinc 6.6.29 every single one has crashed. All say something is absent such as this Sat May 16 03:26:33 2009 rosetta@home Output file threading_lb_test1_hb_t317__IGNORE_THE_REST_11832_2317_0_0 for task threading_lb_test1_hb_t317__IGNORE_THE_REST_11832_2317_0 absent Wu examples http://boinc.bakerlab.org/rosetta/result.php?resultid=251397003 http://boinc.bakerlab.org/rosetta/result.php?resultid=251390439 http://boinc.bakerlab.org/rosetta/result.php?resultid=251367304 http://boinc.bakerlab.org/rosetta/result.php?resultid=251358761 Any word when this will be fixed?

26) Message boards : Number crunching : Anyone else having several 1.67 errors? (Message 61184) Posted 14 May 2009 by nick n Post: I have only seen about 3 or 4 WUs crash on my mac mini since I started it here last year but several 1.67 WUs have crashed recently. My other computers are doing the same thing too so is this happening to anyone else or just me? EDIT Also I forgot to say that these were in my logs after a few of the crashes on both my mini and P4 machine Wed May 13 18:29:25 2009 rosetta@home Task ccf_fair_filt_0.5_chunk_1_8_hb_t360__IGNORE_THE_REST_1PKLA_4_10673_40_0: no shared memory segment and Wed May 13 18:29:25 2009 rosetta@home Task ccf_fair_filt_0.5_chunk_1_8_hb_t360__IGNORE_THE_REST_1PKLA_4_10673_40_0 exited with zero status but no 'finished' file

28) Message boards : Number crunching : Problems with Minirosetta Version 1.64/1.65 (Message 61065) Posted 9 May 2009 by nick n Post: Yeah we should start a 1.67 thread
29) Message boards : Number crunching : 100 Teraflops (Message 61006) Posted 4 May 2009 by nick n Post: As of now we have 102 tflops so we are again over 100!
30) Message boards : Number crunching : Recent average credit (RAC) (Message 60974) Posted 3 May 2009 by nick n Post: I have also noticed the same. What is going on?
31) Message boards : Number crunching : credit pending more than 2 days? (Message 60943) Posted 1 May 2009 by nick n Post: There was a problem a few days ago that was just fixed so the server is still behind a bit. It should all be good in the next 24 hours.
32) Message boards : Number crunching : Problems with web site (Message 60879) Posted 29 Apr 2009 by nick n Post: Hi. Is the validator really running i know it's been slow for a while, but i have three tasks that have been sitting there for hours and still nothing. pete. I think it is broken even though the server stats page says it is ok. I have several tasks waiting as pending too.
33) Message boards : Number crunching : 100 Teraflops (Message 60858) Posted 27 Apr 2009 by nick n Post: Well it was good while it lasted.
34) Message boards : Rosetta@home Science : new supercomputer (Message 60815) Posted 25 Apr 2009 by nick n Post: Now it would be interesting to see how fast a system with 30 thousand GPUs would be. If you used 30,000 of something such as this http://game.amd.com/us-en/unlock_radeonhd4870x2.aspx?p=1 which has 2.4 Teraflops each you could have a 72000 Teraflop server! That would be crazy!
35) Message boards : Number crunching : Resource Share Obsolete? (Message 60743) Posted 19 Apr 2009 by nick n Post: nice write up! I agree it is junk!
36) Message boards : Number crunching : BOINC 6.6.20 released to public (Message 60608) Posted 11 Apr 2009 by nick n Post: will update, just to find an excuse to not study calculus. Haha!
37) Message boards : Number crunching : Oh My. Did I Win? (Message 60600) Posted 11 Apr 2009 by nick n Post: cool!! I have never seen that list before. Apparently I also got the best RMSD on one too haha http://boinc.bakerlab.org/rosetta/rah_results.php?UserID=201050
38) Message boards : Number crunching : 100 Teraflops (Message 60394) Posted 30 Mar 2009 by nick n Post: Nice!!! and when we get GPU crunching maybe we can get into the petaflops range like a few other projects
39) Message boards : Number crunching : 64 bit version and/or processor optimized versions (Message 60354) Posted 28 Mar 2009 by nick n Post: someone please make optimized clients now that the source code is available!!!!
40) Message boards : Number crunching : CPU Optimization, GPU utilization: so sad! (Message 60353) Posted 28 Mar 2009 by nick n Post: yeah they NEED to do both the gpu and cpu optimizations soon! We are loosing so much processing power by not doing these things. As an example on the project milkyway@home some gpu enabled computers have almost 200,000 Rac! We really need to take advantage of all of these ready to use GPU's. Here is one card that on its own has 1 teraflop of power!! As of this writing the whole project had 90 teraflops so just getting a couple hundred people using a card such as this could double our power.
