Message 1684710 - Posted: 27 May 2015, 10:43:09 UTC

Hi Team,

I am running a large machine at work, i am downloading and uploading the WUs from my phone data when i arrive and leave the office via a mobile hotspot.

The problem i am having is the machine only ever has enough work to keep it going for about 18 hours, so if i was ever to take a day off or over the weekend the machine will fail to continue crunching WUs.

I have setup my preferences to download 10 days worth of work units but i can hardly say that i helping.

Any tips on how to get SETI@HOME to send my office machine more work units?

If you look into my current machine its the 16 core, 1 GPU machine.

Cheers
Sam

Your 16 core computer is full at the moment with 200 tasks in progress.

You are limited to 100 task per CPU (not cores) and 100 per GPU.

So 18 hours seems about right with that limitation, and not having constant internet access.

1st, the BOINC will calculate the OFFLINE time of the network & computer...so don't worry about it! it will figure it out that you don't have 24h for computer crunching! ;)

2nd, your company doesn't want you to crunch data with BOINC...so you are probably in the gray (if not black) zone list! ;)
so I shouldn't do that often...though my company has a policy of having BOINC previously installed - I continue to use it on an office PC...though I'm using it 24h on computer & restart every morning...and the connection is SSL 3.0 with WCG version of BOINC (the link is downloadable on my signature)...

3rd, I would have a coffe break with some of the IT guys. ;)


btw, I don't see a task with 64.800s! :/

Hi Klik, the funny thing is I am the IT guy on-site, my main question for this thread was wanting to know if I could force download more work units.

Also the machine in my own machine that I have positioned on my desk and off the work network hence me using my personal mobile for data transfer :)

And sorry what do you mean in regards to the 64 seconds?

Regards
Sam

There kind of is a way to have your machine cache more work for SETI@home. Each instances of BOINC connecting to SETI@home is limited to 100 tasks for each type of computing device as it was already explained.
You can run more than one instance of BOINC on your machine. So each instances would be its own indentation queue. If 100 CPU takes are run in ~18 hours on your 16 thread boxen. Then configuring 4 instances of BOINC, each limited to 4 CPUs, should give you ~72 hours worth of work.
So if you are interested in doing that one of the old threads explaining the processes can be found

Wow thanks HAL9000!

I will attempt to set that up today, now if i disable to GPU on one of the additional Boincs will it see that and not download GPU tasks....

I will let you know how i go, hopefully this can assist other users that may be offline for most of the time, or run offline machines.

If you disable the GPU in the other instances it will be exactly that. Disabled. Using <no_gpus>1</no_gpus> for each other instances is probably the easiest way to go given that machine only has the 1 GPU.
If you had several GPUs. Then you could configure each instance with a separate GPU using <ignore_cuda_dev> or <exclude_gpu>.

Well, there are set limitations on SETi@home (as some guys have told you)...so unless you've been able to have more than 18h of work done - maybe you should think about donating your CPU to some other grid?
At least two more other projects would also get your CPUs bussy till monday morning.

64.800s = 18h...I got you wrong, thinking that you have 18h of 1 WU...but you got 18h of total work on that rig... ;)
