panic: CURAND_STATUS_LAUNCH_FAILURE on GTX1080

[Billthered]

Hi all,

I've encountered the following error after setting up a system with the configuration details as below, using the precompiled version of mumax3:

mumax 3.9.1c windows_amd64 go1.3.3 (gc)
CUDA 8000 GeForce GTX 1080(8192MB) cc6.1, using CC53 PTX

During the simulation, the generation of the mesh and even the relax() phase works properly. However at the end of relax(), before the simulation runs it gives:

panic: CURAND_STATUS_LAUNCH_FAILURE

goroutine 16 [running]:
runtime.panic(0x8af1a0, 0xc9)
        c:/go/src/pkg/runtime/panic.c:279 +0x11f
github.com/mumax/3/cuda/curand.Generator.GenerateNormal(0x14d61f0, 0x70b000000, 0x80000, 0x3f80000000000000)
        C:/Users/Arne/src/github.com/mumax/3/cuda/curand/generator.go:41 +0x7a

If I set the temperature to 0K it works fine. It seems that the error with CURAND comes from compatibility with the GTX1080 architecture and may need update to CUDA8.0?

BVLC/caffe#4324

Would building Mumax3 with CUDA8.0 solve this issue? I've tried, however I could not build. I got an error related to the CUDA header files, exactly as in issue #18, despite I changed the //windows lines in the different cgoflags.go to be

//#cgo windows LDFLAGS:-LC:/cuda/v5.0/lib/x64 -LC:/cuda/v5.5/lib/x64 -LC:/cuda/v6.0/lib/x64 -LC:/cuda/v6.5/lib/x64 -LC:/cuda/v7.0/lib/x64 -LC:/cuda/v8.0/lib/x64
//#cgo windows CFLAGS: -IC:/cuda/v5.0/include -IC:/cuda/v5.5/include -IC:/cuda/v6.0/include -IC:/cuda/v6.5/include -IC:/cuda/v7.0/include -IC:/cuda/v8.0/include

Actually I also tried different ways and paths to include the headers but only manually adding the full path of a header file seems to work, not any path in the //#cgo commands. What could cause this?

Thank you for your help and comments!

Plz help!!

see issue #1186

[syockit]

Seeing you closed the issue in DIGITS, is this one still an issue here?

[vandrearczyk]

I had the same CURAND_STATUS_SUCCESS (201 vs. 0) check fail when running runtest with ubuntu 16.04, GTX1080 and cuda 8.
I realised that I was still using some cuda 7.5 libraries with:
dpkg -l | egrep 'digits|caffe|libcudnn|libnccl|cudart|nvidia'
Some cuda7.5 libraries were still in /usr/lib/x86_64-linux-gnu/
I purged cuda and nvidia and reinstalled cuda 8. It seems to be working now.

[MartenArthers]

I have the same CURAND failure as Billthered had when running with Temp on my workstation with quadro p600, latest driver. When running om my laptop geforce gt720m the temp fuction works fine.

Any solution?

Thanks.

[godsic]

Please try the windows build provided in #175 . It is linked against CUDA 9.1.

[MartenArthers]

Thanks for your help. The version I had running was 3.9.1, as there was no pre-compiled version of 3.9.3. When i run the mumax3 application in the 'mumax3.10beta.cuda91.win64.zip' it says it it missing the dll file. The only thing I could think of was to copy the dll files of the 3.9.1 to the 3.10 folder and change the names to xxxxx64_91.dll. This didn't work. I'm very new to programming and go language so what I did probably was pretty ignorant. Any clue as to what i should do?

NB: I followed the link:
I started a draft release: https://github.com/mumax/3/releases/tag/untagged-a550dd2b59d233cef40d @ALL: please add/modify bullet points in the draft release notes.

As I thought there might be new dll files there, but this page can't be found...

[godsic]

Please install cuda sdk 9.1 (not newly released 9.2!).

Thanks again! I tried this but still no result. On my laptop I have CUDA development 9.1, graphics driver 391 and mumax 3.9.1. This configuration works with Temp. On my workstation I now have al components of CUDA 9.1 (so also CUDA development 9.1) and graphics driver 397. I tried this with the beta3.10 in the way I dicribed and 3.9.1 mumax. Any new ideas? 2018-05-17 17:01 GMT+02:00 Mykola Dvornik <notifications@github.com>:

Is it necessary to install Golang? This is a difference between my laptop and workstation... However, since all other functionalities of mumax work on my workstation without installing Go I thought it was not necessary.

Have you copied DLLs from 3.9.1 version to 3.10 folder? If not, then most likely there is a bug in curand library that we don’t have control of. Please try to configure cuda9.1 on your laptop and test mumax3.10 there. Please also don't copy / rename / modify any DLLs yourself as it makes debugging this kind of bugs virtually impossible.

[MartenArthers]

Message from yesterday: *Thanks for your help. The version I had running was 3.9.1, as there was no pre-compiled version of 3.9.3. When i run the mumax3 application in the 'mumax3.10beta.cuda91.win64.zip' it says it it missing the dll file. The only thing I could think of was to copy the dll files of the 3.9.1 to the 3.10 folder and change the names to xxxxx64_91.dll. I'm very new to programming and go language so what I did probably was pretty ignorant. Any clue as to what i should do?* So yes this is exactly what I did, copy the dll files and change the names... Where do I get new dll files for 3.10? the link in issue #128 is dead. Sorry if these questions are very stupid, and thank you so much for helping me. 2018-05-18 10:42 GMT+02:00 Mykola Dvornik <notifications@github.com>:

…

Have you copied DLLs from 3.9.1 version to 3.10 folder? If not, then most likely there is a bug in curand library that we don’t have control of. Please try to configure cuda9.1 on your laptop and test mumax3.10 there. Please also don't copy / rename / modify any DLLs yourself as it makes debugging this kind of bugs virtually impossible.

@Billthered Does 3.10 work for you?

[godsic]

@MartenArthers
We included DLLs in previous versions of mumax3 for the sake of convenience, as there is no need to install CUDA SDK then. It is quite likely that such approach won't work in the future as Microsoft is hardening the way DLLs are linked and preloaded to avoid their spoofing.

AFAIK, if CUDA SDK is configured properly, then there is no need to copy any DLLs to mumax3 folder as system will automatically pick them up and preload for you. BTW, on the machine where 3.10 was compiled, CUDA SDK is installed in C:\cuda\ (the path could be configure in Advanced Mode of the CUDA SDK installer).

Anyway, if mumax3.10 fails to launch for you, then please make a screenshot of the error and attach it to this conversation.

I deleted the dll's and now it does work! Probably it didn't work before since I had the 9.2CUDA, then i copied the dll's to the folder, so after installing cuda9.1 it still didn't work because of the wrong dlls. Thanks so much!! I have some unrelated questions. Feel free to answer any if you know the answer and have the time, if you don't have the time don't bother (you've helped me so much already). They are in order of importance to me. *I am analyzing the borders of generation of singledomain -> vortex -> multidomain in nano/micro scale disks of different sizes and materials. Next step is so analyze the resonance frequency of the vortex core to an alternating Bfield.* 1. should the cellsize be < 1*exchange length, or < 0.5*exchange length? In the verification paper the range 0.25-0.5 is mentioned, however online I find multiple papers that use cellsizes of 0.5 to 1.0 * l_ex. (with programs other the Mumax, mostly). My simulations would go significantly faster if I could do cellsizes of ~1*l_ex. 2. Can I use the rk45 with Temp? In the paper it says no, and in issue #61 it is mentioned the results are different. However Arne does not completely rule out the possibility in the same issue. If rk45 is not allowed, is it allowed to use variable dt in the Heun solver? Or only fixed? (In the beta10 it is possible to run with varDt, where this was impossible in 3.9). Also what is the rkf56 solver and is it physically correct with Temp? fix or var Dt? 2. The B_sat of a material goes down to 0 with increasing temperature, with 0 at curie Temp. Is this incorporated in Mumax, or should I calculate and enter a different M_sat with a high temperature? I'm almost sure that I can keep the B_sat the same, as the added B_therm field ensures the magnetization is never the complete B_sat. With this last assumption, could I run a simulation without Temp, but with a lower B_sat, and get similar results? (for the sake of a faster simulation using rk_45 instead of heun). 3. What error/step is allowed, what will be the consequence when this is too high? How do I find a balance? 4. What is the effect of the damping parameter? I notice in different papers they chose a higher alpha just to decrease simulation times. Is just justifiable when researching the evolvement from a randommag to its 'qualitative ground state' (single domain, vortex, or multi domain, but not centered)?
