Solved: Re: after-build tests partially fail

Leonard_K_ · ‎09-25-2015

Two after-build tests fail for the intel TBB source:

make rml (which by default also makes rml_test - which fails):

./test_rml_mixed.exe 
Assertion my_make_server_routine failed on line 86 of file ../../src/rml/client/rml_factory.h
../../build/Makefile.rml:150: recipe for target 'rml_test' failed

make[1]: Leaving directory '/path_to_src_dir/tbb43_VERSIONoss/build/linux_intel64_gcc_cc5.2.0_libc2.22_kernel4.2.0_debug'
Makefile:50: recipe for target 'rml' failed
make: *** [rml] Error 2

VERSION is confirmed to atleast be either 20150611 or 20150728.

Also the make-target `test` fails, at some point:

TBB Warning: RML might limit the number of workers to 7 while 15 is requested.

Makefile:44: recipe for target 'test' failed
make: [test] Error 2 (ignored)

The error in the `rml` target is that the assertion failed that 'factory' could not be opened - at least that's the comment above the critical line:

Assertion my_make_server_routine failed on line 86 of file ../../src/rml/client/rml_factory.h

Same thing for the VERSION.

I could not check why both assertions fail (first: fail to open `factory`; second: thread hangs even after pkill and reaches code that shouldn't be reached). The issue not only exists on GCC5 but I also tested it on GCC4.9.

Any idea why the tests fail? Bug in the source or libraries?

This is *not* the rml I'm just running 'make && make test'. Could you please double-check this? I.e., TBB_VERSION=1 LD_LIBRARY_PATH=. ./test_tbb_fork.exe 2>&1|grep RML returns TBB: RML shared when shared RML is in use, and TBB: RML private when no shared RML found.

Hello larkey,

1. Shared RML is not documented and I do not recomend to use it and especially to include it to the package. Private RML is located inside tbb libraries.
2. fork() stuff is more interesting, do you have any fork limitations on your system? this is a simple fork() test so it should work pretty stable on systems where fork works well.

UPD for fork(): this test does not work with shared RML.

Oh, well, I came across it since I found quite some packages that wanted to load libirml.so but couldn't due to it missing (namely unity-editor, the Linux-Build for the unity3d engine).

So I did some research and ended up building it via these sources. Are they supposed to ship the binary library when distributing the engine?

Not as far as I know I have any fork() limitations. The specific problem seems to be that the forked process gets killed but still continues to run (for some time - at least as long as it needs to reach the test).

If you need more information I could provide, feel free to ask and thank you for the clarifications on RML.

No, this library is not needed for unity editor.

Like I wrote before fork() unit test does not work with shared RML. So no information is needed.

I ran ldd on the Unity editor binary and it did search for it.

returns

TBB: RML shared

when no shared RML found.

Ah, so because I've built RML before, it automatically loaded the shared RML and thus failed. I thought I had to explicitly tell it to use the shared lib.

So this seems to work now and shared RML should not be built using these sources. Still weird though that Unity wants to link against RML:

LD_DEBUG on unity-editor binary:

26751:	find library=libirml.so.1 [0]; searching
26751:	search path=/opt/Unity/Editor/Data/Tools:/opt/Unity/Editor	(RPATH from file ./Unity)

26751:	trying file=/usr/lib/x86_64/libirml.so.1
26751:	trying file=/usr/lib/libirml.so.1

Well, this seems to be a Unity-issue then - as long as there are no other sources we should build the shared lib from, am I correct?

Hi. is late, but test opencl stack provide by oneapi suit also complais about libirml.so library

for example. run the clinfo program

what is the exactly package ship this library in your APT (debian) repository?

Hi,

Thanks for reaching out to us.

>> oneAPI suit also complains about libirml.so library

Could you please elaborate more about the issue and the steps you have followed to reproduce the issue?

And please do let us know the version of oneAPI being used.

Thanks & Regards,

Noorjahan.

Hi

thanks for the reply

first for all. my steps is a little "hacky"

My system is archlinux. for fetch the sources, in this case, from APT repository (like describe the document posted above) i have installed the `apt` program in the system. then active the repository in the apt sources file and then fetch the packages with `apt upgrade`.

For get the list of the packages provided by the repository, `apt-cache search oneapi`. at the time at wrote the post, the latest version of oneapi is 2021.4.

After fetch the list of packages, use a `fetch` program provided by the suite `apt-move` for get the URL of the packages (`fetch -t intel-oneapi-runtime-opencl` ), then download with `wge`t and then unzip with `bsdtar`.

Prepare a native arch package with the binaries unziped and install in `/opt` and then use `patchelf` for patch the rpaths for no interfiere with the system packages.

Because the libraies provided by the APT packages seems need a dependencies (viewered with `ldd`), star dowload the dependencies with the same method. in my case, points to `intel-oneapi-runtime-tbb`, `intel-oneapi-runtime-tbb-common` and `intel-oneapi-runtime-compilers`. then extract and install used the described method

Add the ICD file points to intel cpu opencl like `intel-oneapi-runtime-opencl`package do, run the `clinfo` program provided by `clinfo` package

then get this:

see clinfo_log.log attached

the error:

watching the `clinfo' output with `strace`, i see the output posted above, then i think my problems is because the library `libirml.so`not exist in the system, and searching the wrole apt repository, no one packages provided that file.

what package provide that library?

as note, i thry to use opencl cpu with Xeon E5-2650-v4

Hi,

Thanks for providing the information.

>>My system is archlinux.

As per the oneAPI base toolkit system requirements, archlinux is not supported by oneAPI.

Please refer to the below link for more details:

Thanks & Regards

hi

that distribution share the same version of all components with other distribution like mine, so is not a trammel, also, oneapi (some components) is opensource, so any distritbution or system can take it and install without problem. this is not a exception

so please. dont toss the ball to other roof

also you can explain (like you asked me) what is the real impediment for this refuse to work

in that document only i can see what is the distribution you test, but not what is the real impediment (custom kernel with custom patch with custom modules builded with custom compiler, for example)

i'm not angry, just a little cold with that reply

greetings

Hi,

Apologies for the delay.

libirml is distributed only with tbb4py packages, for example through conda and pip channels

Please refer to the below link:

https://www.intel.com/content/www/us/en/develop/documentation/installation-guide-for-intel-oneapi-toolkits-linux/top/installation/install-using-package-managers/conda.html

We understood that you are having some issues with libirml.so. oneTBB 2021.4 doesn’t need libirml.so and OpenCL from oneAPI 2021.4 package shouldn’t require it as well.

we think that there may be a mix of old/new versions of software installed in the user system. So we suggest you to have a clean environment and reinstall the oneTBB package.

To install a standalone oneTBB package please refer to the below link:

https://www.intel.com/content/www/us/en/developer/articles/tool/oneapi-standalone-components.html

If the installation procedure for oneAPI packages is not working smoothly on Arch Linux, you can use open-source packages from the below link. The installation is as simple as unpacking the archive and running vars script

https://github.com/oneapi-src/oneTBB/releases/tag/v2021.4.0

Thanks & Regards,

Noorjahan.

Hi

Unfortunately, tbb4py only install if have python 3.5 to 3.8, my system uses 3.9

and about mixed versions. i have sure i'm doing the correct when use patchelf for set the rpath for hail the versions

install newer TBB in system is not allowed at the moment because some software use older version (2020.3-1) and is not prepare to use newer versions. (https://github.com/PixarAnimationStudios/USD/issues/1471)

Hi,

Intel oneTBB is not tested on ArchLinux. As it is not supported officially by intel oneAPI we cannot provide the support from our end, but you can raise this request in the below GitHub page with clear steps to reproduce.

GitHub link:

Thanks & Regards,

Noorjahan.

hi

i have already open issue in the intel github repository (get opencl cpu stack open source)

https://github.com/intel/llvm/issues/3025

but unfortunately not ETA

greetings

NoorjahanSk_Intel · ‎11-24-2021

Hi,

We are trying to reproduce the issue from our end on an environment similar to yours.

Could you please provide the below details to reproduce the issue:

OS version

OneAPI version

Also, provide the detailed installation steps that you have followed.

Thanks & Regards,

Noorjahan.

sl1pkn07 · ‎11-24-2021

Hi

System: Archlinux (full sync)

Oneapi verson: provided from Intel's APT repository. 2021.4.0 (in the moment i test) (see how i install it below)

Steps i follow to install:

install this packages:

https://aur.archlinux.org/packages/khronos-ocl-icd-git/

or generic opencl stack (one of two)

https://archlinux.org/packages/extra/x86_64/ocl-icd/

https://archlinux.org/packages/community/x86_64/clinfo/

for Intel opencl CPU stack, i use this PKGBUILD (script for make archlinux packages)

this download, uncompress, setup and package the bits downloaded from Intel APT repository
