Post:
My 64-bit Linux machine has been running the Nbody 1.50 single and MT versions without any problems.
All my work units finish properly.
It would help a bit if my wingmen could be bothered to finish their work units so that I could see if they validate correctly.

Having read about their problems, I don't much fancy trying out the Windows version!

Btw I take it your GPU is at stock clocks?

Yes. I don't know how, or even if it is possible, to overclock it.
According to the Nvidia control panel, it runs at 810 MHz.

GPU: Nvidia GT 610 Driver: 350.12

CPU: Intel Pentium 4 560 3.6GHz

OS: Windows 7 32-bit

BOINC: 7.4.42

Average of last 8 work units: 1827 seconds

I believe that my GT 610 is about the slowest GPU that can correctly run on this project.

It will probably be able to run the applications anyway - but the question is whether it will run them fast enough.

My new GT 610 is turning in the current work units in about 70 minutes each.
Compared to my slow CPU, this seems very quick to me!

Is there going to be a 32 bit Windows or Linux GPU version of the N-Body application released?

Before I go out and spend the money, I would like to know whether an Nvidia GeForce GT 610 would be a suitable GPU for this project.
According to this page, it is CUDA-Enabled, with a Compute Capability of 2.1
https://developer.nvidia.com/cuda-gpus
My computer only has a 305W PSU, so I can't really put in anything much more potent than this.
If it is unsuitable, maybe it could be used for other projects?

My single processor machine isn't getting any Nbody work, although there appears to be plenty available.
Are single processor computers without hyperthreading not supported by this application?

My old 2.8GB Pentium 4 Northwood core only has a single processor, with no hyperthreading.
It wouldn't get any n-body work units.
Are 2 processors (real or virtual) required in order to run n-body work?

Renderfarm also uses an Multi-Threading application, but that runs fine on my single P4 machine.

My 3.0GHz Pentium 4 with hyperthreading is getting loads of N-Body work, but my other, 2.8GHz Pentium 4 without hyperthreading machine is getting only:

Neither machine has a GPU.

Do you need a multithreading CPU to get work, or have I got the preferences set wrong for that computer?

Every time there's a new search that you download, there'll be a download around that size.

This project is actually not that bad. After the last data file download (stars-82-3stream.txt), I have received several work units that use that file to work from.

As for the work units being short, even my 12 year old 233MMX can finish one in only 20 hours. The longer ones usually take 40 hours!

My slight complaint is not about the size of the work units, it's about the size of the data file download.
The file size was 8.17 MB, and is a bit much for my slow, expensive dial-up!
I hope that there aren't too many more large data file downloads like that.

Are you using an optimized app for it? That would help if not.


I had a look at zslip.com, but I don't know which version I need, and I couldn't find any instructions.

My Intel Pentium 233 MMX processor doesn't have any SSE.

I will feel safer using the stock app, but thanks for your advice.

I have attached my old, very slow 233MMX to this project, and also I can only run it for 14 hours a day max.

The longest work units I usually get take 41 hours, so I can send the result back only an hour before the deadline!

If my old computer is slowing the project down too much can the admin tell me, as then I will detach it.

For what it's worth, my 11 year old 233MMX is very reliable, and has always returned accurate results, no matter what project it is doing.
