[quote]You skipped a few important settings:

Use at most xx% of memory when computer is in use
Use at most xx% of memory when computer is idle

Since my last post I upgraded to 5.8.11. It looks like they are new to this version so I didn't have them before. Anyway, they are now set at 50% in use and 100% when idle.

So, if a thread uses about 150 MB, should I set it to use about 60% of my 1 GB of memory?

I'd rather not cut back to 3 processors yet. That would be a whole 25% reduction. Of course, it it means that the missus won't impose a 100% reduction I'll look into it, but I'll explore the other options first.

Based on what you just said, I'm about to change my settings to save apps in memory but until then, here are my current settings and stats:

% of time work is allowed: 84%
[/br]
Processor usage:
Do work while computer is in use: No
No restriction on time of day
Leave apps in memory: No
# of processors used: 4
Use at most: 100% od CPU time
[/br]
Disk and Memory usage
Use at most: 70 GB disk space
leave at least: 1 gb free disk space
use at most: 75% of page file

Network usage:
connect to network: every 3 days

What dows DIMM mean, exactly? Is that the memory card, or a GB of RAM?
What are channels? I'm using 4 processors. Are channels something different?
If threads use 150 MB each, shouldn't 1 GB be plenty?

My objective here is to optimize BOINC's performance and have enough memory left over to runn other programs and I suspect 1 GB isn't enough. There must be some benefit to loading up a computer with up to what, 16 GB of RAM? I just want to know if a $300 investment will make my computer run a little better and keep me and my wife happy with it.

No Windows here. Mine is a Mac with OS 10.4.8.

My thinking is that with computer's 4 processors sharing only 1 gig of memory, each will have only 256 megs which doesn't seems like a lot. I'm only running Rosetta and it doesn't stay in memory so I'm not too worried about performance on other tasks but my wife still thinks the computer is "slow". What she's talking about is how fast web sites load since that's mostly what she uses our computer for. I think this is mostly a function of the connection. However, there is sometimes a slight delay while BOINC makes room in the memory and I'd like to avoid this since it actually is pretty annoying. with more ram I thought I could make it resident in memory and keep it running all the time, makiing us both happier.

And by the way, please feel free to correct me if I'm wrong about any of the technical stuff I've said.

I'm running BOINC on a Mac Pro (4x2.6 Ghz, 1 GB RAM) and I'm thinking of adding another gig. What effect, if any, is this going to have on either RAC or system performance with BOINC running?

Thanks in advance.

I just installed BOINC and my PC downloaded its first chunk of data and has finished working it. For the last several hours it has been displaying "uploading" for the first chunk and "downloading" for the next.

Anyone have any thoughts on what might be the problem? Thanks in advance.

To save anyone who might help me some trouble, here are some numbers concerning my machines and an approximate ratio of credit claimed to credit granted.

Laptop
Measured floating point speed: 1537.54 million ops/sec
Measured integer speed: 2815.93 million ops/sec
Credit Claimed/Credit Granted: 1.0

Old Mac
Measured floating point speed: 419.78 million ops/sec
Measured integer speed: 1349.27 million ops/sec
Credit Claimed/Credit Granted: 0.4-0.5

New Mac
Measured floating point speed: 2161.2 million ops/sec
Measured integer speed: 5683.94 million ops/sec
Credit Claimed/Credit Granted: 1.0

Old PC
Measured floating point speed: 1580.25 million ops/sec
Measured integer speed: 2688.1 million ops/sec
Credit Claimed/Credit Granted: .8-.9

And by the way, the "Old Mac" above with its dual 866 Mhz processors was hot stuff 4-5 years ago, but based on its numbers seems to be far outclassed by the other machines - even the garden variety PCs. Do these numbers seem right for a machine of this vintage?

As you can see I have 4 machines, two of which seem to be claiming slightly less credit per WU than what is granted while the other two claim less and are granted less than half what they claim. Any ideas on what this means? Is it bad and if so, how do I fix it?

In have a little old G3 iBook with OSX ver <10.3.9. In my quest to bring every bit of computing power to bear I would like to get R@H running on this platform as well as my other computers. Is there a version of BOINC around that I can use to make this happen?

Post:
Oh, it's my computer. I just want to conceal BOINC's operation from my wife. She has (and correct me if I'm wrong) the mistaken belief that it will slow down the computer. I have BOINC set to not do work while the computer is being used so I don't think that it will adversely affect the computer's performance.

I have it running without graphics or as a screensaver but there is still the BOINC logo in the lower right. I'd like to eliminate even that.

When you install BOINC, it askes you to select an installation type. You can select "single user", shared, or service. If you don't intend to view the graphics etc. then perhaps you want to run it as a service.

I should point out that if your intention is to hide the fact that BOINC is running from the owner of this PC, then you are not following the project guidelines about ONLY running on machines YOU own.

Is it possible to have R@H run completely behind-the-scenes? Ideally, I'd like the only way to see the results of my computer on the R@H site.

Thank you for your help.

BTW, Not sure if this maters but I will be running this on a new (60 day old) but pretty generic PC.

I have an older Power Mac w/2 866 mhz cpus. The efficiency of this machine is about 0.83 and has an average turnaround of about 0.34 days... Can I impove these stats and if so, how?

Thanks for your replies, gentlemen but I think that I may have solved the problem. Well, maybe not solved, but fixed it anyway.

I had tried to access the OSX installation guide but for some reason wiki thought I was trying to modify it and wanted me to sign in. After perusing the rest of the extensive instructions and finding nothing helpful, I decided that a hobby shouldn't be tis complicated and deleted BOINC. I restored it when I was notified of your replies and wonder of wonders, it started downloading just fine. In fact, I think I may have even detected a new sense of urgency and eagerness in BOINC's calculations. Perhaps after this brush with oblivion it has realized just how easily it can be replaced by some generic screensaver and has decided to be more compliant.

As for the messages, I tried to copy them but was unable to paste them into my post.

Anyway, thanks for the help guys. If I have any more trouble, I'll be sure drop you a post.

I just removed SETI but Rosetta still doesn't get new work. (I tried to copy the messages from BOINC manager but can't seem to paste them here.)

Can I have a connection problem specifically with Rosetta but still connect to the interet in general?

Post:
About three days ago my BOINC ran out of work and hasn't been able to get more. The messages tend to be along the lines of

Insufficient work, requesting more
Deferring communication with project for X hrs, X min, and X seconds

The second message is returned from both my projects. (Seti and Rosetta)

Does anyone have any idea what's wrong, what I can do to find out what's wrong, and what I can do to resume computing?

Thank you for your help,
Chuck

For a few days now BOINC has had no work and has been idle. The messages indicate that it has requested more but none has been sent. Until it stopped, it was working just fine.

Anyone have any ideas why it stopped or any suggestions to make it start again?

Thank you for your help,
Chuck
