Bad Experience Working Einstein Project

Topic 225144
(moderation:
Back in mid March I attempted to run GPU Gravitational Wave Search projects with the following results:
1 Successful project on 3/19 granting 1,000 units of credit.
10 projects still pending.
40 or so project finished with an "Error While Computing" message.
Since I have, and are currently successfully running, Boinc Projects plus the one successful Einstein Project, I don't believe the errors are with my system. So, until I hear this issue has been addressed for the Einstein Project I must stop processing your projects as I have other projects that I would rather donate my time and PC time to and gain credit for.
Thank you,
Brent

The Gamma-ray pulsar binary search #1 tasks will also run great on your gpu

Great, I thought we had addressed it a "thousand" times ...

It has been but as long as new people keep coming to try helping what they see on tv but with inferior hardware the problems will continue. The Project needs to find a way to detect that the gpu you have is not capable of running the units you are asking for and pop up a note in the Notices section and not send you any tasks. We aren't talking something outside the 32bit barrier of detectable ram here, it's properly listed as only having 2gb of ram so a script should be able to handle the problem. Also a note where you check the box to get the GW tasks might help too.
To me it's alot like me checking the box to get AMD tasks on my Intel cpu or Nvidia gpu the Project says other tasks are available but you haven't selected to get them.

the project does try to estimate how much GPU ram is required, and compares to how much GPU ram your GPU has. this is all done on the scheduler side of the project (check your connection log at the website) but there are two flaws in their methodology.
1. they only check GLOBAL memory. when they need to be checking AVAILABLE memory (both are available to BOINC). a lot of the gravitational wave tasks do require just below 2GB of memory, and could theoretically run on a 2GB GPU. but the problem is that in most cases, the 2GB GPU still doesn't have enough because some portion of GPU memory is allocated to other things like running the desktop environment. this drops your available memory below the limit of what's needed and causing errors.
2. the project can only see GPU memory for the GPU detected by BOINC. this is an issue with BOINC that it only presents the "best" GPU in the system. so if you have a mixed setup, one with a capable GPU and one with an old GPU with low memory, there's no way for the project to know that you have a GPU that's not capable. you'd need to setup a manual <exclude_gpu> flag yourself.

I am assuming that BRPs means Binary Radio Pulsar Search (Arecibo, GPU). If so, I cannot download any of these tasks!

It appears that the Gravitational Wave Search is the only GPU task I can download from the Einstien@home project. In fact, when I try to download the other 2 GPU projects, I get only Gravitational Wave Search files (even though I have NOT selected them) and I don't see how to block these unwanted downloads. It looks like I have no choice but to be done with this project.

sounds like you're doing something wrong. no one else is having trouble downloading gamma ray tasks.

First, thank you Ian&Steve C. as I was able to successfully download the Gamma-ray pulsar binary search #1 (GPU) application and run it thanks to your suggestions. Unfortunately however, it ended up finishing with a "Error While Computing" message after eating 12,673.63 units of computer time! Bye, Bye Einstein! I am through with this project.
