O yeah, Zika. My fav project on WCG.
The 5960X eats through those like butter. biggrin.gif

Right now I will bunker up some of the Cosmology then bunker a butt load of Zika.
I will get the FX3120 drop in tomorrow and have it sit on Cosmology.

Huh, seems I can get past a certain number of Cosmology units on my main rig.

Hello all, trying to get going on this over the weekend. Pardon the "newb", but I have to start somewhere.

Assuming I can figure out some functional percent of what I am doing, I have 2 machines I can devote to this for the specified time period and maybe 3 depending.

Trying to sort through setup and software first.

How does planning work in terms of who runs what on what (to get the most bang for the buck)?

We don't generally have an overall team plan, since our team philosophy has always been that everyone runs what they like, and all projects are welcome.  :D

 

That being said, there will be a good amount of back and forth going on in this thread, along with watching the leaderboard once the compettion begins.  As the event progresses there will be a fair amount of tactics that are discussed, and if we need to make a shift in resources, one of our seasoned crunchers will usually alert us with a post in the thread.  A look through last  year's thread will give you an idea of how things went. http://www.overclock.net/t/1597391/7th-boinc-pentathlon-june-5th-19th-2016/0_50

Next dumb question: I notice someone mentioned running in VMs for jobs that run better on linux.

It would ease my setup and future involvement to do this sort of thing using KVM, but I don't know how to gauge the handicap involved as I have no idea of the character of these compute jobs.

Any advice there?

GPU pass-through is still rough enough that I wouldn't like to deal with that, but CPU only computes are "easy".

There are very few CPU tasks, in all the BOINC projects, that will run better on Windows, so since you are in Linux you should be pretty well set.

 

For the GPU projects, outside of MilkyWay@Home, most of the projects are now fairly comparable in Linux or Windows.  Depending on what AMD GPU is used there can be some difficulties running in Linux, due to the state of the AMD GPU Linux drivers on older cards.

If you're a bit lazy to deal with project switching just crunch the marathon project until we have a solid lead and then decide to do whatever at the last project aannouncement. tongue.gif

For Cosmology@Home make sure virtualization is enabled on your CPU (VT-d/VT-x) if you don't mess with app config. Per their admin it is 2GB memory required per job with v-box.

So I grabbed as many Cosmology@Home units as my client would let me, after increasing my stored work to the maximum. I have 20 work units, I'm not sure if that's a lot or not. I was going to crunch them and then bunker them for the start, but everytime I suspend network activity, BOINC stops crunching and the units give me the status "Waiting for network access." Is this some sort of counter-measure to prevent bunkering finished units?

It has to do with the way the Virtual Box wrapper works for Cosmology tasks. 

 

What you can do is limit your upload rate to something like .1 KB/second in BOINC Manager.  Although, with Cosmology that might not allow you to grab many more tasks, since there is a limit on tasks in progress per host.

The planck ones might need network access. People have been bunkering the multiple-hour-long legacy workunits.

I aborted all the May 7th deadline planck ones and got all legacy workunits with a deadline of May 14th. I crunched a few test work units to make sure they work properly on my system.

Blocking the upload via hosts or firewall works, and the Virtual Box tasks will still run.  The Virtual Box tasks appear to just have a requirement that "Network Activity" is allowed for the client, but don't appear to actually need the connection to process the tasks.
