Not getting work from O1MD1CV tasks?

Hi!

Server status says, there are over 9.700 tasks available for the O1MD1CV work units.

But although I explicitly allowed these, I'm only getting this from BOINC manager:

30.11.2016 15:28:42 | Einstein@Home | No work is available for Multi-Directed Continuous Gravitational Wave search CV

So what is wrong here?

Seems like the CV WU are only

Seems like the CV WU are only for "really fast computers", although i do not know what that exactly means. I am getting only the G gravitiy WUs.

Both your computers are AMD

Both your computers are AMD which only get O1MD1G workunits. But not right now because I paused all GW work. See my message over at Multi-Directed Continuous GW production work begins

I don't want O1MD1G wus anymore, I wanted CV. But if this is for Intel only then that's bad... :-(

You guys should put such informations in the scheduler response somehow, it's not obvious from the application page that this works like that...

Any particular reason why?  As I understand it (and I could easily be wrong) the more computationally intensive work is being directed towards hosts better suited to perform it in a reasonable time.  Three separate supernova remnants are being examined and a continuous GW detection could come from any of them.

It's nothing to do with 'Intel only'.  It's to do with host capability - probably in a fairly rough fashion - but with the purpose of not overloading 'lesser' hosts with longer running work.  I have both Intel and AMD hosts.  Some of my Intel hosts (eg. i5s) get CV and the rest (eg. i3s) get G.  I'm quite happy with this arrangement because G work seems to be completing a bit faster on average than CV work, despite the host being (a bit) less capable.

 

Cheers,
Gary.

I'm collecting apps and hours (for WUProp) and I've reached my goal (with O1MD1G). Wink

What are the rules for

What are the rules for getting O1MD1CV or O1MD1G tasks? What CPUs or graphics cards are supported?  I have never received any "O1" tasks and I have a pretty kick-ass system.

There are only 10 kind of people in the world, those that understand binary and those that don't!

First of all one has to enable tasks in preferences section, if not by default.

O1MD1CV tasks are for fast CPUs. O1MD1G tasks are for slow CPUs, but currently not available, see status section, nor are O1-GPU tasks.

What is considered a fast

What is considered a fast cpu? Can someone give me a model number as an example?

"

The O1MD1CV search is limited to the following CPU models:

  • Intel Core i3-3225
  • Intel Core i5 and Core i7
  • Intel Xeon E3
  • Intel Core2Duo E8
  • Intel Xeon E5-1
  • Intel Atom X52 and Intel Atom X56
  • Intel Atom X546 and Intel Atom X556
  • Intel Atom X7
  • Intel Pentium G2 and G8
  • Intel Pentium G64
  • Intel Pentium G32

"

 

** But those are like product families. At least some comparable CPU models can receive CV tasks. Intel Xeon X56xx for example are also able to get CV tasks, even though these Xeon CPUs don't have AVX instructions. They use SSE instructions to process CV tasks.

It's there any hope that.AMD

It's there any hope that.AMD processors will make the list anytime soon?
