1) Message boards : Number crunching : Os-X Time comparisons PPC vs. Intel (Message 3433)
Posted 30 Apr 2008 by A/C
Post:
A couple of questions (very simple). Firstly, are the optimized apps officially endorsed and/or provided by the MilkyWay administration? Secondly, will the project administration notify all project participants that optimized clients are available for use, along with instructions on how to install them? Then there's the question of whether optimized apps give some platforms (ie operating systems and CPUs) advantages over others based on particular optimizations that are being done. Like are the optimizations being done to fully take advantage of each platform's capabilities.

Basically this is what I see it comes down to. Those using non-optimized apps will get less RAC (recent average credit) because the workunits will take longer to complete, while the ones using optimized apps will end up with much more RAC while crunching less. Am I missing something or oversimplifying here?

[EDITED]


The optimized app are not endorsed by the University. However, this project is open source so we will not restrict people from doing this. Also, the administration says we can't "notify" people, but if Cruncher wants to make a thread to list optimized apps, I will be happy to make it a sticky.


I see. I brought up the question of certain optimizations being more advantageous to some platforms more than others because it's known that there can be differences in the efficiency of optimizations across platforms. Though, I'm thinking more of the type of compiler used rather than a 32-bit vs 64-bit system difference. And I was wondering how the Core 2/Core Duo Intel-based Mac optimizations compare to any Core 2/Core Duo Windows-based ones.

On the issue of notifications. If people can't be notified that there are optimized apps via email, than I suppose a sticky "optimizations" thread would be the next best thing.

Do I need to buy a fire extinguisher for my apartment?


Yes, all humans should have one.

All WU's in progress for this rig should be recycled asap. Motherboard failure. Gigabyte GA P35-DS3L (refurb) from NE. Melted components near 4 pin power connector. Health of remaining components TBD. If there is any good news, I was granted an RMA for credit. Crunch on.

Thanks to all who got the Server back!

Voltron


wow...Gigabytes are usually pretty stable. I usually go with Asus or Abit myself.


I've heard of about a dozen newer Gigabyte boards that have caught fire or had melting where the MOSFETS are. It was always with boards that where overclocked. I don't know what caused this one.

I'll be adding extra cooling on my Asus MOSFETS soon.
5) Message boards : Number crunching : Some host productivity comparisons (Message 3096)
Posted 11 Apr 2008 by A/C
Post:
At the moment I am running Milky Way on three hosts, so I thought I would compare the runtime of the tasks to see what hardware is best suited to run the Milky Way application.

They all run XP
The host 857 is a Sempron 3000 that does a task in 530 sec.
The host 13208 is a P4 2650 MHz that does a task in 640 sec.
The host 13541 is an AMD Athlon 1200MHz that does a task in 850 sec.

So, what’s the limiting factor that favours my old Athlon in comparison to the newer hosts?


Maybe floating point. That and you're using more memory on the Sempron. Not sure.

Consider an upgrade.

7) Message boards : Number crunching : updated granted credit (Message 2658)
Posted 24 Mar 2008 by A/C
Post:
Personally I don't have a problem with what the granted credit has been set to. I'm staying, and so is my overclocked CPU.



Just a question -

http://milkyway.cs.rpi.edu/milkyway/show_user.php?userid=2095

What sort of overclocked CPU are you running.. a Pent III :)

Just jabbing at you...nothing personal. I am staying as well, with a couple of my non-overclocked machines, the overclocked ones I reserve for projects that pay enough to keep it, like this one.
http://abcathome.com/show_host_detail.php?hostid=37811


You must be talking about my Pentium 4. I don't think it's nice, you laughin'. You see, my Pentium don't like people laughing. He gets the crazy idea you're laughin' at him. Now if you apologize, like I know you're going to, I might convince him that you really didn't mean it. Nah just kidding, that was from an old Clint western. :D

That's an old Pentium 4 I had on my board awhile ago to run some benchmarks. I installed my q6600 again and so I'm using that now. http://milkyway.cs.rpi.edu/milkyway/show_host_detail.php?hostid=9119. It's not the best OC, but considering that it's B3 stepping and I'm using 1.41V, it's not that bad either. Those are some pretty high numbers you have at ABC. If I had to guess I'd say you're running above 3700 MHz. Very good overclocking.

I can understand your reasoning about the credit system, and I'm not suggesting people should leave if they don't like it or anything like that. It's up to them. The way I see it is, even with the lower credit numbers, the total credit will still be much higher for machines that turn in more WUs. So I'm happy enough with that.

heh i had another machine in the works which i was building to bring in on this also :) a Q9450 which a buddy of mine is gone build for me... i hope you guys correct this crazy mistake before its finished i really wanted to break it in here :) if not ABC will work just as well i guess :) :)

now if they will only release the damn chip lol,,, it sucks to have the $$$$$ and have to wait lol.. passed up so many fantastic QUAD deals so far it hurts lol.


That's going to be a good processor. I've already checked out some of the benchmarks for it and it seems to have good increase in floating-point over the Q6700. The Xeon X3350 verion is already available.

You won't have problems getting WU's.


Cool, more WUs for me. :D

part of the problem might be that i'm running db_purge right now -- as we have about 600,000 WU results in the database, which makes everything a bit slow. once it finishes things will probably be more available.


Great. Thanks for the update.

Post:
A/C try leaving apps in memory if you want to solve that problem.


Thanks for that. I checked the option and after running benchmarks all of the suspended tasks resumed again, including the Milkyway tasks.

@banditwolf-So are you keeping apps in memory? No more errors?

@A/C-Are you keeping apps in memory?


Hi JRenkar. If you mean the setting in the client that says "Leave applications in memory while suspended", no, I don't have that option checked. I don't think it's selected for any of the BOINC projects I'm doing.

I seem to be having a problem and I'm not sure if it's the client or the MilkyWay WUs. Whenever I finish running benchmarks, the tasks from other projects resume but the MilkyWay tasks don't. After the benchmarks I have to exit BOINC and restart it (4.10.30) to get them going again.

I want new work !

i don't want to run Cosmology@home on both cores, they use way too much RAM and makes my PC lag ...



let me look and see wahts going on... there should be work available.


Indeed there is. I just got 20 WUs. 8-)

i'm hoping these are just because of labstaff taking down the machine for awhile. are these problems still happening?


All I see is:

and then this:
