installation from source, cuda backend

[gopalakr]

Installation seemed normal, but  example fails at runtime. What am I missing ?

Hi

We apologize for the confusion.

The installers available on this website are for older commercial versions of ArrayFire (v2.1). ***THESE ARE NOT OPEN SOURCE*** and require licensing.

We are actively working on bringing out installers for the open source versions. Until then, please try building the source using our github wiki.

We are here to help you solve any build issues that you may run into.

I was in fact trying to build the source,

installation CPU backend would fail saying this --

cc1plus: error: unrecognized command line option ‘-std=c++11’

make[2]: *** [CMakeFiles/bin2cpp.dir/common/bin2cpp.cpp.o] Error 1

then changing the -std=c++11 to -std=c++0x, it went further but broke again.

XXXX/arrayfire/src/backend/cpu/blas.cpp:47:1: error: expected unqualified-id before ‘using’

XXXX/arrayfire/src/backend/cpu/blas.cpp:54:1: error: expected unqualified-id before ‘using’

XXXX/arrayfire/src/backend/cpu/blas.cpp:68:1: error: ‘gemm_func_def’ does not name a type

:

So I set BUILD_CPU and BUILD_OPENCL to OFF which then compiles fine for the CUDA backend but then breaks at runtime..

Let me know if I can provide more info.

[Shehzan Mohammed]

Thanks for the info.

Your CPU compilation is failing as you do not have C++11 capable version of gcc (4.7 or higher).

As for CUDA, if you are running the helloworld example as is, it should not be calling the transpose kernel at all.

Can you post a code snipper if you have modified it?

Can you run the tests (using make test) and let me know which tests fail?

We test internally on CUDA 6.5 so this will help us clear the bugs ASAP.

Thanks

[gopalakr]

I can only run the CUDA option, so compiling works only with the following settings in CMakeLists.txt

OPTION(BUILD_TEST "Build Tests" OFF)

OPTION(BUILD_EXAMPLES "Build Examples" ON)

OPTION(BUILD_GTEST "Download gtest and check for updates. Necessary if you change compilers" OFF)

OPTION(BUILD_CPU "Build ArrayFire with a CPU backend" OFF)

OPTION(BUILD_CUDA "Build ArrayFire with a CUDA backend" ON)

OPTION(BUILD_OPENCL "Build ArrayFire with a OpenCL backend" OFF)

To build tests you need to turn BUILD_GTEST on too. But lets leave that for now.

Can you send me the code you are running? The build id that you put in your code output does not exist so I have to assume that you have made some commits of your own.

Without looking at the relevant parts of code, especially the example, I will not be able to comment on it.

So please send the me example code as well as any other relevant changes that you have made so that I can help you out further.

Shehzan

[Shehzan Mohammed]

My bad. I forgot to check the master branch. The build ID is there.

Can you send me the code from the example?

Shehzan

[gopalakr]

I have not done any changes to the code or commits myself, only trying to compile things as they are.

It is surprising that It'd use transpose !

[Shehzan Mohammed]

Yes it is surprising. It shouldn't be doing that.

Can you check out the devel branch and build that? We made a few bug fixes.

Shehzan

[Shehzan Mohammed]

Ok I've got it.

Transpose is called when the print happens. So it is not surprising.

If you comment out all the af_prints, it shouldn't crash.

I'm not sure why its failing though. I'm working on it.

I cloned devel and tried building, same cuda backend. If you want me to update g++ and cuda to 6.5 Ill do that!

I did comment out the af_print for this output.

[Shehzan Mohammed]

So I've just built it with CUDA 6.0 and its working fine at my end.

Just to be sure, git you clone with "git clone --recursive"? (There should be files in arrayfire/src/backend/cuda/ptx/*).

If you did not run these 3 commands:

git submodule init

git submodule update

git submodule foreach git pull origin master

[gopalakr]

Yes, I do see these directories, in ptx.

The error seems to suggest invoking cuda kernel is wrong.

with the af_print commented out, its the CU error from jit.cpp

[Shehzan Mohammed]

I tried to build this for Tesla K40c with compute 35 and even that works fine.

Can you try this. Its a long shot though.

PTX Headers: https://drive.google.com/file/d/0ByGyhTmHFow9LVJvVV80TVRXZ28/view?usp=sharing

I've build the attached links for libafcuda.so and ptx_headers with gcc 4.6 and cuda 6.0 (compute 30) and c++0x.

Replace your libafcuda and ptx headers with the extracted ones. They should go into build/src/backend/cuda/

Note: my source commit is 6d797e6 from the devel branch.

Shehzan

[gopalakr]

OK did these, it seemed to have gone further (the af_print part may be) but stuck on the jit thing.

I'm observing a similar error to gopalakr, as shown below:

As you can see, it happens for a different GPU (GTX590) and already with CUDA 6.5, so it does not seem to be related to that.
Curiously, I still get it passed on 67 out of 68 of the ctest (except for Test_reduce_cuda), as shown below:

I hope these information may help you figuring it out. Let me know if you need more info.

[Pavan Yalamanchili]

Hi SrM,

The OpenCL problem occurs when clBLAS and ArrayFire are using different versions of libOpenCL.so. Can you make sure you are using the same OpenCL libs are being used for both these libraries.

Hi

We are aware of the reduction failure on CUDA and are investigating it. You can follow it on our github issues page.

We have also updated the master branch with the latest updates. You can try to build that.

Let me know if you run into the same problems again.

Shehzan

[srmuniz]

Hello Pavan.
Thanks for your superfast reply!

I saw some mentioning of this in the "Known issues" page, but I'm not so sure how to determine that. I mean, I followed the instruction in the Wiki and did not notice anything strange while installing clBLAS, which apparently worked fine, and later I looked into the Makefile produced by cmake and it seems to point to the right places. In addition, I would expect the cmake scripts to find the same versions of libOpenCL.so, as they are basically running from the same place, under the same conditions, (folder, session, etc.)... But, of course, I might be wrong about that.
Any suggestion on how to make sure?

All the best!

[Pavan Yalamanchili]

Hi,

FindOpenCL.cmake is not part of the default CMake modulse. clBLAS and ArrayFire ship with their own versions of this file. They are looking for files in different order of preference. If you have more than one OpenCL SDK installed on your system, you may face issues like this.

We will update the wiki to reflect this as a possible issue. To use CUDA's OpenCL SDK on linux, you need to do the following.

export OpenCL_ROOT=$CUDA_PATH

export LD_LIBRARY_PATH=$CUDA_PATH/lib64:$LD_LIBRARYPATH

After doing the following, delete the build directories and start from scratch.

Hey Muniz

Can you run make test with "CTEST_OUTPUT_ON_FAILURE=ON make test".

This will result in a detail print of the reduction failure. That would be helpful.

==================================


As you can see, it seem that the updates produced some other changes (apparently introducing a couple of new errors).

Cheers!

Thanks for that info.

For the index tests, we added some data, so go ahead and run

git submodule update
git submodule foreach git pull origin master

We are working actively on the other issues.

Hi Pavan.

After following your suggestios (below), while trying to build arrayfire with OpenCL, it gets much further, but it still does not work. It does build some files, but towards the end it gives similar errors to basically all the OpenCL executables test files when trying to link/build them:

==================================

Any other ideas??

[srmuniz]

Yep, that last update fixed the other (new) two errors. Now, only the test 45 (Test_reduce_cuda) fails, as before...

In any case, thank you very much (to you and Pavan) for the incredibly fast replies and updates!!
You guys are amazing.

Thanks a lot,
Sergio.

Gopalkr, Sergio,

Can both of you print out the number of threads and blocks when transpose is called?

Add the print statements to src/backend/cuda/kernel/transpose.hpp before calling the kernel (line 93).

printf("threads %d %d\n", threads.x, threads.y);

printf("blocks %d %d\n", blocks.x, blocks.y);

The error you both are seeing are related to invalid launch sizes,so this information would help.

Thanks for that.

Can you call af::sync() between the A = randu() call and af_printf()?
This will help by checking if the failure is happening before transpose and is only showing up there.

[srmuniz]

Still gets exactly the same output...

However, I noticed that if I comment out all the af_print() commands the program follows on a few more steps (see below),  up to the line
B(seq(0, 2), 1) = B(seq(0, 2), 1) * -1;
where it throws an error at memcopy, instead of transpose.
This seems to indicate that the arrays A and B are created okay, and A's values can even be accessed for certain operations (as in sin(A)), but one gets an error when launching kernels with copy operations. What do you think? Any new clue here, or is it something you were expecting before?
Let me know if there is something else I could try here.

[Shehzan Mohammed]

Can you post the output you got when you had af::sync() added in the code?
We made another bunch of bug fixes yesterday to the devel branch. Do you mind testing that? Also, when configuring cmake, turn CMAKE_BUILD_TYPE to "Debug"

Which distribution of linux are you running this on?

I appreciate your patience with us. As we have refactored the code from older versions and we rely on users like yourself to report issues beyond our testing and help us solve them.

Shehzan:

The output with af_sync() was, as I said, exactly the same one (before that change)...

The output in my last message was obtained by keeping af_sync() (where you suggested), and, in addition, commenting out all the af_print() commands below it.

I'm running Ubuntu 14.04.1 LTS (GNU/Linux 3.13.0-36-generic x86_64).

As for the repo updates, I have Good News!
After doing a simple "git pull", and changing the cmake call (setting to "Debug"),  I get, at last, helloworld_cuda working ok, i.e.: without the previous errors!
Way to go!!

However, the error with of test 45 (Test_reduce_cuda) still persists, while running ctest...
Except that now the ctests are taking much longer (about twice as long, mostly due to CPU) to complete.
In any case, Progress!! ;o)

Would you mind letting us know what was the problem?

Thanks,
Sérgio.

[srmuniz]

Ok, not so fast...
Here goes another information that you may find useful. At least amusing...
I just rebuilt it, returning CMAKE_BUILD_TYPE to "Release" instead of "Debug".  Guess what happens?
....Yeah, there comes the error again(!):

A Internal error in .../ArrayFire/arrayfire/src/backend/cuda/kernel/transpose.hpp(102):

CUDA Error (9): invalid configuration argument

If I go back to "Debug", doing
cmake .. -DCMAKE_BUILD_TYPE=Debug -DBUILD_CUDA=ON -DBUILD_OPENCL=OFF
it works again... (as in my last message)!

So, why do you thing this happens?
What is the main difference between the two?

Cheers,
Sérgio.

[Pradeep Garigipati]

Hey Sergio,

This is Pradeep from ArrayFire. Technically, there should be no difference at all as one would expect. My first guess would be that some uninitialized variables are been taken care of by debug build, where as in release it is bailing out as no such checks are carried out. We will look into it and let you know as soon as we fix it. 

Thank you for updating us with your new results.

Pradeep.

[gopalakr]

OK, so I got the latest repo and compiled for Debug and it does work. Although, I did change my cuda to 6.5 and gcc to 4.9

I can work with this now.

Thanks 

Gopala

[Pradeep Garigipati]

Great!, Pavan pushed couple of bug fixes yesterday evening. Are you still getting the error in releases mode after pulling latest changes ?

Regards,
Pradeep.

[srmuniz]

Even with the latest (i.e. today's) updates, I still get the error at helloworld_cuda when using "Release", and the same ("undefined reference") errors while linking libclBLAS, when trying to build with OpenCL. However, tuning off OpenCL and using "Debug" still does the trick for me.

[Shehzan Mohammed]

Hi

Can you create another thread for this issue?
This thread has become long and has differed from the original question.

Thanks
