(Message 9795) Posted 22 Feb 2005 by old_user2147 Post: > That is why rocks > are/were used in bed-warmers when central heating is/was not available, long > time to heat up, long time to cool down. > :) > Very interesting, since I sometimes think my bed-warmer has rocks in her head, but I've never had the guts the tell her, directly. As for the "long time to heat up" situation, I've found that some spontaneity, creativity, & ingenuity, can substantially shorten the warm -up time, but this can vary greatly on your bed-warmer's mood. But, creative persistance usually works. I agree with your last point completely. In issues resulting in an argument, or even events perceived as a transgression on my part, whether accurately percieved, or not, my bed-warmer can take an unbelievably inordinate period of time to cool down; Sometimes lasting for days. During periods such as this, my bed-warmer's heat-up period may be extremely long & difficult, or even non-existant, with all my efforts ending temporarily in futility. I'm in my mid 40's, and after having over 25 years experience with bed-warmers, I still find I've only come to understand, at most, maybe 70%, of how they operate. My current bed-warmer, and I, have been in an exclusive one-to-one mutual ownership situation, for almost 6 years now, and I still do not completely understand how she works. Bed-warmers are an absolutely endlessly fascinating subject of study, for me, and I've devoted much of my adult life to this pursuit. I'm sure I'll never have a full grasp of how they function, but they enrich my life immeasurably, so I am more-than-willing to live with what I perceive as "an occasional idiosyncrasy", which I'll never understand, nor comprehend.

Now I know how non-technical ppl feel when they read one of my technically oriented posts!!! Mo, you're absolutely right, re: The UK - American dialects. I worked w/several Brits a few years ago, and the differences in our use of the English language bordered on startling, to say the least!!! When thier conversations were amongst themselves, and they were speaking "fast & furious", I missed around 20% of thier conversation! It's clear to me us Yanks speak "Amercanese", which varies greatly by region, and sometimes even by neighborhoods w/i the same city!

I did work as a university employee, briefly, early in my career, and recently did a 9 month consulting project for a major university. While I cannot speak directly of Oxford specifically, my experience with universities is that the environment is very different than private industry, since the projects are usually non-profit, and much of the work is done by PhD students & volunteers, who are often very busy with many other matters besides just the project-at-hand. Often, even the investigators & thier assistants are busy writing funding proposals, academic papers, instructing, giving lectures & seminars (possibly involving traveling), etc., etc. I guess this is a long way of saying the project ppl may not be aware of the prob, may not have immediate resources available in technical people or $$, or an "authorized" person may not be available to "officially" communicate any problems, or problem status. The fact that this was a weekend, makes it even more likely one of the above scenarios could occur, IMO, since its even more likely people are doing other things not project related (including enjoying thier personal lives). So my statement was conjecture, based on my prior experiences working w/i other universities, & was not based on any "hard" info. Strat

Heh - I've seen you mention, several times, of your use of English as a 2nd language. I wouldn't ever concern yourself with this issue when communicating with us in English. Your sentence above, is one of the BEST examples of communicating an idea using the English language, that I've seen on this forum! ;-) Strat BTW - I suspect there may be a bit more delay, then usual, in fixing the upload problem, and with communication, due to the problem occuring on a Friday going into a weekend. Just my suspicion.

I think your concerns with running Distributed Computing projects on laptop computers is a valid one. My team's experience, over several years, has shown that heavy duty 24/7 DC tends to be pretty tough on the lappys. Usually the probs are thermal or HDD related. Since I've never run DC on a lappy, I can't speak from my own experience, as to whether thier was sufficent maintenance or adequate cooling measures involved in those that had probs. But there have been a fair amount of problems, including out-right failures, when some peeps attempt to run 100% DC 24/7 over long, indefinite, periods of time on a laptop. Some lappys overheat relatively quickly, and other's have died after a year, or so, of non-stop DC. The newer lappys may have better thermal management, & be built more robustly, so they may be more immune to the stresses of DC. But, speaking for myself, I would not personally consider a lappy as a good candidate for a 'high use' DC machine, even though the Centrino lappys, using the new Iraeli designed Pentium 'M' cpu, turn in some very impressive performance numbers!!! JMO BTW - My comments above are directed strictly towards laptop use only. I run my desktop machines well overclocked, and hard & heavy, stopping just short of a Chernobyl incident! ;-) Never had a known DC related hardware problem, over the several years I've been running DC. .

31) Message boards : Number crunching : Just for fun... (Message 9331) Posted 15 Feb 2005 by old_user2147 Post: <b>- OT -</b> FYI - OK. This may be bordering on thread raising-of-the-dead (thread necrophylia???), and is pretty off-topic, even though it could possibly be argued there is a tie-in, since this is a BOINC forum, & BOINC could, in a way, be thought of as an outgrowth of the S@H project. I just didn't know any other place to post this, and some peeps may be interested. S@NL (Seti Netherlands) has organized a final international SETI Classic gauntlet for the three week period, beginning 21 Feb 2005. Fredsel has been kind enough to open up a section of the S@NL forum for public access (though I suppose one could "formally" register as a forum member, if they prefer). There's currently over a half dozen teams, representing probably several dozen countries, already signed up. If you'd like to participate: sign up as a member of an existing team - whether it be international or country-specific, add your current team, form a team, or run as an individual. The purpose is to have fun & enjoy some interaction with other DC teams from different parts of the world & different cultures, all sharing the same goal: The enjoyment of thier DC hobby, some friendly competition, & hopefully, the furtherance of SETI science. If you started out your DC hobby in SETI Classic, as many of us here have, and want to have a little fun with one last short run amongst many like minded peers, this is the last chance before the servers shut down for good, and the show is over. If you've never participated in a gauntlet, you may find yourself unexpectantly enjoying the competition & comraderie, of a newfound activity. I haven't yet decided if I'll join, but if I do, I'll be running under Ars-Technica Team Lamb Chop, and Ars-TLC (or any other team) would be happy to welcome any prospective participants. This is a form of inclusive competition, where the commraderie of entire group of gauntleteers, overides the competitive spirit of the individual teams. "The superset of the gauntlet supercededs the subsets of teams."

Even though I never poked around much in the BOINC folder, I figured BOINC must be archiving models or model data, since my newest machine had just under 1GB in data, & my older high producing machine had >6GB. Guess yiour suggestion is one of those things I'll have to get around to doing as time permits. thanks, again @All- Well, 48 hrs have passed since my 4.13 ---> 4.19 upgrade. All six machines seem to be nicely crunching away on all twelve models. Several models have even successfully phase transisitoned, w/o incident. No models, as of yet, have since completed & uploaded, which, IMO, is the supreme test. But I feel pretty good 'bout the way things are going, and suspect things will go smoothly upon the models' completions. Strat

I guess I may as well go for it, since 4.19 does have some additional file upload/download features, which may help insure more robust file x-fers (AKA rationalizing something to do, 'cuz I'm bored-as-a-gourd whenever my wife works these straight-thru multiple weekend shifts - You know it's pretty bad when you spend Satuday nite defragging your HDD's). :-( The professor mentioned a major revision is due in March, but for that upgrade, I'll probably due my usual sit-on-the-sidelines for a few weeks, while the other guinea pi...uh...er...my fellow crunchers adopt & evaluate the new rev for a while. ;-) So I probably won't be upgrading, after this one, for a while. Thanks again, Strat BTW - I decided I'll back up the entire BOINC folder, & set a Sys Restore Pt first. I'm blown away by the fact that my BOINC folders display as 4 - 6GB in size, as shown under thier 'properties'!!! Whoa baby...I've run lots of DC proj's, but this sure seems awfully large to me! Yowsa. :-0

Does it not just run, but run stably, & upload well, too? M$ released thier monthly patches Tuesday, so I'm planning to do my monthly maintainence this weekend, & figured I might upgrade from 4.13 to 4.19, if all is well w/4.19. Currently, though, 4.13 seems to be doing quite well for me . Six machines is a lot of work to undue; And 12 models is a lot of lost work to replace, if 4.19 is a dud! So Yea or Nay??? Strat

(Message 9059) Posted 10 Feb 2005 by old_user2147 Post: > <b>mo.v queried:</b> > Could I please add my name to Graham's question - how do all of you measure > the temperature? Hi Mo & Graham - The most usually available & obvious place would be somewhere in your BIOS. Many BIOS' have a section somewhere for cpu voltage, temp info, fan speeds, etc. Asus calls this section, quite appropriately, "Hardware Monitor". The disadvantage to using a motherboard's BIOS to monitor hardware is that you can't monitor it in real-time under load, since you must enter the BIOS to get the info. So... Motherboard manufacturers that offer this monitoring ability, often include some software monitoring utilities that run in a M$Windows environment, & display the same info as would be found in the BIOS. Most "Tier One" motherboard manufacturers (Asus, Abit, MSI, Gigabyte), and many others, offer these utilities. They'll usually be found on the CD that comes w/the motherboard, or avaliable from the manufacturer's site, for downloading. For example: Asus calls thier utility "Asus Probe", and comes on an included CD, but is also available on the web site's "support" section, also including newer versions of the utility, available for immediate download. There also are other aftermarket utilities available too. Here's a few of the more popular: <a href="http://mbm.livewiredev.com/">Motherboard Monitor</a>, <a href="http://www.lavalys.com/products/download.php?pid=1&lang=en&pageid=3">Everest</a>, and <a href="http://www.sisoftware.net/">Sisoft Sandra</a>. All these utilities are free, or have a free (lite) version availble. You may have to poke around the site, a bit, to find Sandra's free version. Usually these main sites lead to mirrored sites for the actual download. The latter two utilities, especially Sandra, offer many test, system identification, & benchmarking utilities, besides the basic voltage, temp, & fan speed info offered by Mothboard Monitor. And, (again, particliarly in Sandra's case) they will probably give you wayyyyy more system info then you've ever cared to know about your computer besides temps!!! But there are two major caveats for temp monitoring: 1] You computer's motherboard must have the innate ability to report whatever it is you're attempting to monitor; i.e. cpu temps in this case (this is done by thermal diodes). Not all motherboards do. 2] The accuracy of monitoring can vary greatly. This applies even moreso, when using a 'third party' utility, rather than a utility supplied by the motherboard manufacturer. Motherboard Monitor may be somewhat more excessive in this case, since the user needs to manually configure the software as to which diode measurement function (cpu, mobo, case), and also what technical type of diode (3 kinds), are referenced for the different temps measured (there are, IIRC, 3 types of diodes, and 3 or 4 measuring points to be manually selected. Everest & Sandra, on the other hand, will attempt to autmatically identify the diode function & type, but they may also be in error, as you may, when you manually configure Motherboard Monitor. The best set-up is generally using the software utility that came w/your motherboard (or jumping quickly to the BIOS in the case of temp monitoring) but, as I stated earlier, there is a fair amount of variance (lack of accuracy). It's just the nature of the beast. > Should everyone running cpdn 24/7 be doing this, whatever it > is? Can't say what everyone should do, but as an overclocker, I find these (and several other) utilities indespensible. Even if running at stock specs, I would want to monitor my system, irrespective of whether it's running DC projects, or not. I'd especially want to monitor if running DC though, 'cuz DC is pretty strenuous, especially thermally, and that goes double for newer high performance systems (namely A64 & Prescott). I'll also often run Sandra to help identitfy an unknown machine I'm upgrading or attempting to repair. In fact, I highly recommend running Sandra's "System Summary" under its "Information Modules" section, just to see what you've got "under the hood". You might be surprised. Hope this helps. Hope I haven't bored you to tears. Strat --EDIT-- Ah...beaten to the punch. While I ended up composing a "War and Peace" reply, Geophi got a quick one in!!! :-0 Oh well...two for the price of one! ;-)
