So how much RAM and disk space is needed again? I thought it was something like 6gb?

It is simply the server's silly way of saying: "I can't give you the highmem tasks because you have just about too little memory and I can't give you the standard tasks because there is too little free diskspace".
Free up some diskspace and you should be fine again.
If you have 6GB RAM and 20GB+a bit storage you will be able to take part in most, but not all, Sunflower sessions.

Message 10868 - Posted: 25 Mar 2011, 5:55:20 UTC - in response to Message 10867.  

I'm confused. From the post I read earlier, the big tasks take up to 6gb of RAM.


In order to participate you will need:
* At least one computer
* A 64bit operating system (official clients will be available for Windows and Linux 2.6.15 or higher)
* At least 6 GB of RAM free, preferably more
* At least 20 GB of disk space available for BURP
* Flatrate internet - or be willing to accept around a 1 GB initial download along with 10MB of uploads every couple of hours (depending on processor speed and work availability). Download/upload speed is not important.


I understand the disk problem, but the RAM requirements are less clear. I have 8gb in that machine. Are you saying that there are tasks that require *more* than 6gb? If so, what is the max requirement now? Is this documented somewhere? I looked around, but maybe I missed it.

Look at the server status page. Session 1153 is the main problem and requires initially about 8,6 GB. I constantly get the message too, when there are no other "smaller" sessions.
Before Janus did a tweak these high-mem sessions blocked getting work from other sessions, but now that seems to be fixed, because I don't have that problem anymore.

Good to know. But I am looking for the max. I am going to have to move DIMMs around in my machines, and perhaps more. What will be the maximum RAM requirement?

Absolute max is 12GB (that's the maximal size that the machine which is preparing the scenes can handle without swapping, I haven't seen a scene with such requirements yet). Most scenes will be less than 9GB and I'll try to keep a good mix of sessions in the queue so that as many people will be happily crunching as possible (like now where there is a 5.5GB and a 8.5GB session running for Windows simultaneously). Unfortunately this will not always be possible.

As DoctorNow correctly points out we're currently trying out different algorithms to make sure that work is available for both "low-mem" and high-mem systems so that sessions with high memory requirements do not block people from getting work for the smaller ones.

I would like to crunch again for BURP but the current memory requirements are beyond my budget. (still crunching other BOINC stuff in the meantime)

I have these computers waiting for work (all Linux)

Intel Core i3 (dual core with HT) 2.4GHz 4GB RAM
Phenom 9850 (quad core) 2.5GHz 2GB RAM
Athlon 64 4200+ (dual core) 2.2GHz 4GB RAM

So
. . . . . . . . . . Waiting patiently for smaller RAM req.

You could always add Renderfarm.fi to your project list to keep things running while waiting for less demanding work from BURP.

When do the next sessions (for Windows) start to render?
I just upgraded my quad with another 4 GB up to 12 and can't wait to crunch some WUs again... ;-D

Right about now.
The next low-mem windows session is scheduled to start in about 9 days.

Is there no work for BURP at the moment? Server Status link shows upload/download disabled.

Currently there is work for Windows hosts with 11GB memory or more. During the weekend we may run out of work entirely. The next batch of sessions should be available Wednesday/Thursday next week with work to machines with at least 8GB of memory. Monday is also going to see an extended Monday maintenance session in the afternoon (UTC) to update a raid controller BIOS firmware on the storage server.

The promised preview of the first scene is further delayed but most of the sources of erroneous frames have been discovered and are being corrected by a script on the server.

8 GB on a PC? Really., I know it is possable, but not very common. I thought that the BOINC process was to split up your work into small work units for average PC's to process?

4 GM is more realisitic, and more common now. AND, your app has to share that with other projects.

Otherwise this is not a sharing project, it is a greedy project.

I hope this resource issue changes back to the way it was in the beginning.

These days if you go to a store and ask them to "fill it up" with RAM sticks you'd typically end up with either 4, 6, 8 or 12GB of memory (4x1GB, 6x1GB, 4x2GB or 6x2GB)

4 GM is more realisitic, and more common now. AND, your app has to share that with other projects.

Both of these points have some truth in them. If the memory requirements are above what a particular host can handle then we try not to send work to it.

Total hosts (including old abandoned ones): 17055
Total hosts with or with more than xGB:
1GB : 12253
2GB : 8173
4GB : 3597
6GB : 1912
8GB : 1480
12GB: 589
16GB: 343
128GB 1

Otherwise this is not a sharing project, it is a greedy project.

All projects do not run concurrently on the client at the same time exactly for the reason you describe - it would be almost impossible to fit everything in there. Instead BOINC uses time slots to share between the different projects that you select. This design was not made out of greed (hm... or was it? Now we're getting philosophical...) it was chosen because it is a very efficient way of distributing the computational and memory resources amongst several consumers.

I hope this resource issue changes back to the way it was in the beginning.

For a while we did only sessions with <3.8GB memory requirements. Then Sunflower started and we have mostly been doing sessions with >=6GB memory requirements.
What will likely happen in the future (when we have Blender 2.6x up and running) is that you will see sessions from the entire spectrum - both small and very large.

The memory requirements are something that is decided based on what is rendered. Simple things have lower requirements, complex things have higher requirements. Recently we have been rendering very complex things.

Janus, Thank you for the detailed answer. I really do like to crunch, but all I mostly have is recycled gear that people have given me. Ram I snot something I will purchase for these older units. I try to fill these up if I get enough of one type of Memory Unit.

I look forward to 2.6. Any ETA?

Hehe, that's great! I also have a couple of old crunchers like that.

A good guess for 2.6 would be around this time next month since I'm really bogged down untill then.

I've just finished 2 tasks on a computer with 4GB of Ram. I was 1 of 12 that was able to validate on one of them.

54088

Is there more work for low Ram Linux computers on the way?

I'm trying to reach milestones and this is the one project I'm having the hardest time reaching them.

There will be low-mem work from time to time. It really depends on what people send in and what gets accepted.
