Issue with AMD cards HD6850 and HD7850, they return "Computation Error" on 520 version and run perfectly fine on 521 version, manually replacing files helps only till next restart of BOINC then it downloads old version again.

Issue with NVIDIA, GTX970 runs ok on old 518 version, but performance is 200 million keys per second, and on 519 version it's 1 billion keys per second, again manually replacing files helps only till next start of BOINC app, which is a hassle.

BlackObelisk, may I know how do you manually replace the file? I don't have OpenCL version 520 or 521 downloaded at all in the project BOINC folder for Moo Wrapper. Thanks.

download the Distributed.net 521 client from https://www.distributed.net/Download_clients
Unzip the downloaded file
rename the dnetc.exe file to match the long file name dnetcxxxxx.exe file in the boinc projects/moowrapper.net directory, then copy it in place of the existing file.

Since moowrapper WILL overwrite the file on occasion, keep the renamed copy of the 521 client file around for later recopy.

The NVidia issue is that the Native CUDA cores are a LOT slower then the newer OpenCL cores - but the clients prior to 521 don't SUPPORT OpenCL usage on NVidia.

1080ti for example it's a difference from about 5-6 GKeys/sec to around 10 GKeys/sec - not as bad as your 970 but still a LOT.

It seems like 521 cleaned up some of the interaction with OpenCL driver code so it just WORKS in a lot of cases were the 520 client (or older) don't.

Since the client is literally a drop-in replacement, I don't understand why this small change wasn't made MANY MANY MOONS AGO - shouldn't take much of a change to tell whatever overrwites the client to use the newer client instead?

Because the Admin is just a site Admin and has little to do with the actual software, he can ask for new software but that doesn't mean the people in charge will send it to him.

I'm pretty sure that the site admin IS the project admin for this particular project.

Right, there's only one admin that manages Moo! Wrapper Project at the moment and that's me. :) And for various reasons I haven't been so attentive as I should have been.

But I am working at the moment on getting app and Dnet Client updates out as well as hoping to tweak the BOINC Scheduler to hopefully send duplicate apps more evenly to users. It will take a while and there could be some issues along the way.
