Topic 207638

Hello Smile

 

I started to crunch Einstein again with my little Celeron J1900 + HD Graphics + NV GT730 (later will follow my big machine).

 

- - - - - - - - - -

 

My Intel iGPU didn't got WUs.

I changed the project prefs...

Run test applications?: from NO to YES

...then the iGPU got WUs.

Is there something broken?

 

 - - - - - - - - - -

 

In the project prefs I can un-/check:

1. Binary Radio Pulsar Search (Arecibo)
2. Binary Radio Pulsar Search (Arecibo, GPU)
3. Gamma-ray pulsar binary search #1
4. Gamma-ray pulsar binary search #1 (GPU)
5. Continuous Gravitational Wave search Galactic Center Tuning lowFreq
6. Continuous Gravitational Wave search Galactic Center Tuning highFreq

(Here I can choose:)

Run CPU versions of applications for which GPU versions are available: YES/NO

 

How should be the settings if I would like to have (which is to un-/check or to choose?):

On GPUs 2 + 4 and on CPU 5 + 6

If 5 + 6 WUs are not available then 1 or 3 on CPU

 

 

Thanks Smile

The project only send Intel GPU work to a small range of GPUs and driver versions due to problems with validation on a lot of Intel GPUs and driver versions.
As you have discovered this can be overridden by enabling "Run test applications", but please check if your results validate. If a high number of tasks doesn't validate then please try another version of the GPU driver or stop using your Intel GPU at Einstein.

The short answer is to keep them all checked and let the server handle things, it should give you work according to your wishes except that you won't get work for nr. 2 as there isn't any.

1. This is only for slow devices like Android phones, RaspberryPis etc.
2. Is out of work so no point trying to run it, but at the same time it won't hurt to have it checked.
3. Will only run on CPUs, if you don't want to run it then uncheck it.
4. Will only run on GPUs.
5. Will only run on CPUs in systems that are "less capable", either in terms of crunching power or have less RAM.
6. Will only run on CPUs in systems that are "more capable", stronger CPU and more RAM.
I'm unsure as to what the limits for 5 and 6 are but keep both checked and the server will send the one best suited for your system.

This setting doesn't have any effect at the moment as there are no applications with both CPU and GPU versions.

Thank you Holmis for a

Thank you Holmis for a brilliant answer.  It is  a pretty confusing set of options, even for an experienced person who is coming back to this project after a break.  It must be pretty daunting for first timers.  Your summary is so clear and useful that I'm going to pin this thread.

Thank you!

Cheers,
Gary.

Thanks   I'm a little bit

Thanks Smile

 

I'm a little bit confused now... Wink

 

My PC got for:

CPU: Gamma-ray pulsar binary search #1 v1.05 (FGRPSSE) windows_intelx86

NV GPU: Gamma-ray pulsar binary search #1 on GPUs v1.20 (FGRPopencl1K-nvidia) windows_x86_64

 

Is the following not the related question for this above app(s)?

Run CPU versions of applications for which GPU versions are available: YES/NO

 

Thanks Smile

They are different apps

They are different apps (different plan classes and different data) so that a task completed on a CPU could not be compared with or validated against a task completed on a GPU.  They both use data from the large area telescope (LAT) on the Fermi satellite but are fed with different data files.

So if you say 'NO' to that question but sign up for both FGRPB1 (CPU) and FGRPB1G (GPU) you have the potential to get both types if you have the necessary hardware.  They are treated as different searches.

 EDIT: 25 Sep 2017.  For any new people reading this for the first time, the CPU search has now changed.  The GPU search continues unchanged but the CPU search is no longer looking for gamma-ray pulsars in binary systems (B1).  The new search is FGRP5 which targets single pulsars capable of being detected by gamma-ray emissions.

 

Cheers,
Gary.
