1) Message boards : Number crunching : 5000+ stones pending and growing (Message 59732) Posted 3 Jan 2005 by SimGuy Post: Indeed the Validator is running at a much slower pace. Having 3-4 pages of "Pending" workunits really hurts, especially across 4 systems. Hopefully things will get a little faster once the work-week starts tomorrow :)

3) Message boards : Number crunching : Electricity Prices and SETI (Message 45741) Posted 12 Nov 2004 by SimGuy Post: While here in Ontario we're capped at $0.043 a KW/h, I still ringup the bill quite hefty each month. I pay in excess of $275 CDN a month for electricity and use approximately 6,000 KW in a 30 day billing cycle, but this is for a household of 5. Our water heater, barbeque & fireplace are all natural gas and supplied through a different company. That electric bill is for the lights, laundry applicances (heavy duty Whirlpool Gold washer & dryer), kitchen appliances (20 year old range, microwave, fridge & dishwasher), and for all other electric items in the house. I'd cry tears of joy if my bill was $100 (45 Pounds Sterling).

4) Questions and Answers : Unix/Linux : Compiling SETI 4.13 For a T-Bird on Linux (Message 44616) Posted 9 Nov 2004 by SimGuy Post: First off, I'm not that great with Linux. I can install the OS, tinker with it, configure scripts, install programs and screw around with loading/unloading services. However, one thing I've never done is utilize GCC on the Linux platform to compile my own applications. After reading that the Linux BOINC client isn't optimized for a specific platform, I endeavoured to speed things up on a spare SETI@Boinc cruncher I've got: AMD Athlon 1000 T-Bird Slot A EPoX 7KXA+ KX133 256 MB PC133 SDRAM 100 GB WD Caviar NVidia GeForce 2 GTS Now, I've installed Red Hat Linux 9.0 on this system (Fedora Core 1 won't install correctly on this system... maybe bad disks... and Fedora Core 2 can't boot from floppy as the kernel is too large and this system can't boot from a CD-ROM). The OS is installed with NVidia's accelerated drivers and ready to accept BOINC. Now, I've used a guide to compile the BOINC client with the most appropriate flags that I could find. http://www.pperry.f2s.com/boinc/boinc-compile.html - Thanks Ned! <B>Flags:</B> CFLAGS="-march=athlon-tbird -O3 -pipe -fforce-addr -fomit-frame-pointer -funroll-loops -falign-functions=4 -maccumulate-outgoing-args" CXXFLAGS="${CFLAGS}" I'm just wondering... are these the most efficient flags to utilize on a T-Bird based system? Is there anything else I can add in there to make the Linux client crunch faster? So far my BOINC bench scores (with my compiled 4.13 CVS client) on this system are: FP Speed (Whetstone): 744.42 MIPS Integer Speed (Dhrystone): 2095.57 MIPS

5) Message boards : Number crunching : Please help me with linux and SETI/BOINC (Message 44159) Posted 8 Nov 2004 by SimGuy Post: After tinkering with my BOINC/Linux installation, I managed to find this little gem. http://predictor.scripps.edu/client.php (works for BOINC in general, not just Predictor) Shows BOINC install, daemon installation & bootup daemon installation for all Linux systems. :)

6) Message boards : Number crunching : seti 4.07 (Message 44149) Posted 8 Nov 2004 by SimGuy Post: Forgive me if this has already been answered elsewhere, but is the 4.07 SETI@Home client supposed to roll out to Linux/Mac machines or is it Windows only? My Linux client is still running on a 4.02 client and I was wondering if 4.07 will be made available to us alternative-OS'ers. :) 4.07 decreased my compute time from 6 Hours to 4 Hours for 2 units on a Windows XP system with a P4 2400 @ 2700. Thanks to the SETI crew for fixing the slowdown bug :)

7) Message boards : Number crunching : BOINC failed to login- Check your account ID and try again (Message 4226) Posted 5 Jul 2004 by SimGuy Post: I'm getting it as well, so I think there's a problem with the authentication server on Berkeley's end. :)
