Crunching since 3 days on a not aced 1070 and i see mistakes. 18 of 140 WUs are exiting with error 195
Is this normal? They are only lasting 2 seconds so that's not a big deal.

Hi guy's I just tried a pair of GTX 580's with same result error 195. Am I right is saying the fermi GPU app does NOT support most fermi"s?

This error would seem to support that theory, the STDERR reads.. "Program requires GPU with compute capability 2.1 or higher" Meaning most fermi's will not work here. http://www.enigmaathome.net/result.php?resultid=274421739

Later model fermi's such as the GTX 560 ti might work as they have compute cap. v2.1. Most other fermi including the 560, 570, 580, 590 only have compute capability v2.0 so should not work.

Anyone confirm?

Must be a bug of some sort, but that's either a bug in the app or on the server side. 195 means that the app could not start so perhaps one of the workunit files is missing or corrupted. If it fails on one host, it will also fail for everyone running a resend of affected WU. Just ignore this for now, the server saves a lot of debug info for workunits which fail, so I should be able to find the reason and possibly fix the problem soon.

On start-up, enigma-cuda checks the cuda compute capability of the video card and rejects those cards that are below 2.1. This is not because 2.1 has something that 2.0 doesn't, but because the program is optimized for the modern cards and is very slow on the old ones. On my GTX-420, it runs several times slower than the CPU-based enigma-AV.

I could change the code to allow the 2.0 cards, but this does not make much sense to me as the people with such cards would be more productive if they ran enigma-av instead.

Perhaps it makes more sense to set the threshold at 3.0 so that only the cards with at least the Kepler architecture are allowed to run enigma-cuda.

What are your thoughts?

IMO limiting the cards at 2.1 does not make sense, aren't all the cards listed as 2.0 actually much faster than majority of the compute capability 2.1 cards ?

The GTX 580 is still a decent card, it's certainly inefficient power wise but in most projects I find it performs similarly to a GTX 670. Of course that's still not saying much either but hey, I have what I have. I'm just not sure that ruling out users because there GPU's may not be fast enough is right way to go either? Perhaps test first to see what works & what doesn't.

I'd still like to give the 580's a try, but if it turned out as bad as you say then of course i'd put them to work at a different project where they still have value. I do have better cards so either way I wont miss out.

At the end of the day it's for you guys to decide.

All the best..

I have rebuilt enigma-cuda.exe to allow compute capability 2.0, download the new executables from GitHub. Warning: untested, test yourself.

I have prepared test suite for you to try out:

https://s3.eu-central-1.amazonaws.com/enigma4/test_runs/2.0_test.zip

Inside you'll find 3 bat files to run enigma-cuda with different settings, included executable is 64bit, replace it with 32bit version if you need. Check if it works and tell us what are the runtimes - the app reports runtime once it's done.

Same here on a 1070. Swapped my Asus Strix 970 for an EVGA 1070 SC yesterday. I haven't seen errors on the 970, but since I have the 1070, I see those 195 errors too. Takes 3 secs to fail. Resends seem te complete fine. I did update the driver to 384.76 .
Hope this helps.

Thanks kindly Alex & TJM, i'll give this a crack as soon :)

Weird...I am using kind of a new laptop afterall.

950M should be working as indicated in the GPU list :d

@forretrio, it looks like you just need to install the latest driver for your video card.

The drivers are here: http://www.nvidia.com/Download/index.aspx

Hi Alex & TJM unfortunately the cap. v2.0 test app didn't fare well on the GTX 580 and crashed immediately on start up for all 3 batch files tested.

I have sent TJM the windows logs in hope something might be gleaned from them.

If you need anything further just ask.

Thanks for the assist.

I have 4 rigs 2 t3500 Xeon machines. & 2 dual cores, 1 amd & 1 intel, that will not run the app
New install of win10 on the t3500 + VC2015 still no go. Pulled intel 2 core and install ( i5 4 core and it worked.)

How do I make the Xeon work, Thanks.

Yesterday I have released test M3 batch which has failed.
The app expects lower case UKW & left ring when running M4 task from resume (upper case won't work), but will fail with lower case UKW when running M3 task.
I can easily work around that on the server side, since the input files are autogenerated it's just a minor tweak to use mixed case for M4 and all upper case for M3, but future app versions must be able to read resume files like this - once the batch is running, the input files have their checksums stored in the database and any change will result in download errors.

Run the executable from command line and check for any error messages.
You can use the executable from project folder or just download this https://s3.eu-central-1.amazonaws.com/enigma4/test_runs/2.0_test.zip and run one of the bat files.

I got some of these today as well. GTX 1070 Win7.

if the error message says that "CUDA driver version is insufficient for CUDA runtime version", all you have to do to fix this is install the latest video driver from the Nvidia web site. This may be necessary even if your laptop is new.

Thanks for the advice. It worked properly for the first few tasks.
