1) Message boards : Number crunching : Is it possible to process jobs with 360MB of RAM (Message 70668)

Hi,

Thank you to everyone for your replies.

It all makes a lot more sense now.

My virtual server provider will be upgrading my RAM to 480MB in mid July, so I\'ll see if I get some jobs once that happens.

Thanks again,

Richard.

No not that particular group of messages it isn\'t, line #218 means some are too close together, meaning you are requesting new tasks too close to the last time you asked and the Project Server is automatically slowing you down, no hammering on the door to get in! Line #254 means the Server itself is down for maintenance, meaning no one gets in!

As for low memory it will probably get units but they would process sooooo ssllooww that it may not be worth it! I just checked one of my machine and each unit is taking about 130,000k of memory and then Boinc itself takes another 10,000k or so. That is written kind of funny but probably means 130meg and 10meg so I could be mistaken.


Hi mikey,

Thanks for taking a look, I have taken another look at messages and below are the ones that have appeared since my last posting.

Do you know what else could cause me being sent no work?

Thanks,

Richard.

Hi,

I am trying to process using a virtual server that only has 360MB of memory assigned to it.

Would this be the cause of my BOINC not being given any work units?

Below is a sample of messages.

Thanks in advance.

Post:
Usually if disk space or time estimates or other factors were a problem, you would see a more specific message. The other problem often encountered is that other projects are running and BOINC does not REQUEST more work.. but you case specifically shows \"Requesting new tasks\".

Are you running other BOINC projects? What is Rosetta\'s resource share? What version of BOINC are you running?

I see your machine has 360MB of memory?? I suppose it is possible that most of the current work units require 512. You might post to the Number Crunching board and see if others have ideas. It is more widely viewed.

Hi Mod.Sense,

Thanks for your help.

I am not running any other BOINC projects.

Please see my preferences settings for Resource share and graphics below.

The version of BOINC I have is 6.10.58 i686-pc-linux-gnu

Yes, my machine currently has 360MB of RAM, it\'s a virtual server. It\'s due to have it\'s memory upgraded to 480MB of RAM.

If there are no clues in this post, I\'ll contact the the Number Crunching board.

Please could you let me know if my problem is at that stage yet.

Thanks,

Richard.


Resource share
If you participate in multiple BOINC projects, this is the proportion of your resources used by Rosetta@home 100
Is it OK for Rosetta@home and your team (if any) to email you?
Emails will be sent from Rosetta/BOINC Admin ; make sure your spam filter accepts this address. yes
Should Rosetta@home show your computers on its web site? yes
Default computer location ---
Percentage of CPU time used for graphics 10
Number of frames per second for graphics 10
Target CPU run time not selected

Post:
Well, you are getting the message indicating the scheduler request completed... so you don\'t have a network problem. You settings look reasonable. The project has loads of work units ready to go.... Have you tried updating since the June 6th date shown?

Hi Mod.Sense,

Thanks for your reply.

I ran the command \"./boinccmd --project http://boinc.bakerlab.org/rosetta/ update\" twice for good measure last night.

I\'ve just taken a look at the messages from that point on and they are below.

Do you have any other ideas that I can try please?

Thanks,

Richard.

Hi,

Would anybody be able to help me with a problem with BOINC on a Linux server please? I\'m a newbie to it.

I installed it on my Linux server and it seemed to process one work job and now all I get is as follows:
