Hello my name is João Martins, Computer Science student at the Federal Technological University of Parana - Brazil

We are working with Heterogeneous Computing and would like to be using its cuda-edu platform for a mini-course with university students.

Following your step by step on the Github Wiki, we found an error in the Makefile (sending in attachment), you already Did you have this error?

error_in_makefile

Thanks! João Martins

João,

Thanks for your interest in cuda-edu. I can only provide limited support, but I will look into your issue soon (hopefully this evening). What version of ubuntu are you using? What version of libclang?

Thanks for the help @sean-dougherty. The ubuntu version is 16.04 Libclang version 3.8

sean-dougherty commented 7 years ago

Can you please tell me which compiler you're using and what version?

I am not seeing your problem, but I am using an Ubuntu 14.04 machine. I can try it later on a newer version of ubuntu.

gcc version 4.7.4 make version 4.1 g++ version 4.7.4 clang version 3.8.0 llvm version 3.8

@sean-dougherty would like an info. We will be doing a mini-course at the GPU-Cuda university, but we only have one machine with a video card (GeForce GTX 780), can we perform multiple runs on this machine through cuda-edu? (We are looking for the same style as WebGPU)

sean-dougherty commented 7 years ago

cuda-edu requires a fully c++11 compliant compiler, which means g++ version 4.8 or higher. It's very possible this is why you're getting your compile error. It would be okay for you to force clang to be used. If you edit Makefile.conf, at line 3 you can edit it to be:

CXX=/usr/bin/clang++ ​ Unfortunately, when I run on my 16.04 machine, I get all kinds of include errors when libclang is running in cuda mode (-x cuda). This is when using llvm 3.8. It worked fine for me on my 14.04 machine, which uses llvm 3.4.

can we perform multiple runs on this machine through cuda-edu?

No, cuda-edu does no such thing, since that was the role of WebGPU. How many students will there be?

There will be between 10 and 20 students

I will force clang ++ to version 4.8 here and I'll tell you if it worked. Have you worked with WebGPU?

jfilhoGN commented 7 years ago

It worked @sean-dougherty, really the bug was in the g ++ version, I put it in 4.8 and Make compiled successfully.

sean-dougherty commented 7 years ago

Have you worked with WebGPU?

Not as an administrator, no. You'll need to talk to the people who maintain that project if you need help.

Okay @sean-dougherty. I will be contacting them, thank you very much for the help, I will be presenting to my advisor about cuda-edu.

sean-dougherty commented 7 years ago

I know students found cuda-edu to be very helpful, but you should understand before adopting it for a course that I'm the sole author and I'm technically forbidden from even working on it by my employer. That is, you'll get very limited support from me.

Thanks a lot for the help @sean-dougherty. I talked to my teacher and at first we will not be using cuda-edu, the idea is to try to use WebGPU, but I want to thank you for your commitment to help me set up cuda-edu, in the future we may be using your project.
