[Openmp-dev] [llvm-dev] Failure executing OpenMP applications in BOTS benchmark with clang

[Hahnfeld, Jonas via Openmp-dev]

Hi Mohammad,



moving this to openmp-dev as you mention an assertion in the OpenMP runtime 
(questions about the compiler should go cfe-dev instead of llvm-dev).



I just tried reproducing the issue on my system and was able to run all 
binaries built with Clang 3.9.1 and the latest trunk of the OpenMP runtime in 
Debug mode. (I had to increase OMP_STACKSIZE for UTS, otherwise it kept 
crashing)

Which benchmark do you have problems with and which environment variables do 
you set? Is there anything special about your setup?



Regards,

Jonas

Hi everyone,

I would like to execute OpenMP applications in BOTS benchmark with clang 3.9.1 
but I get the following error:

Assertion failure at kmp_tasking.c(421): taskdata -> td_flags.tasktype == 1.
Assertion failure at kmp_tasking.c(439): taskdata -> td_flags.started == 0.
OMP: Error #13: Assertion failure at kmp_tasking.c(421).

Here is my machine spec:

Linux pp-multicore 3.19.0-25-generic #26~14.04.1-Ubuntu SMP Fri Jul 24 
21:16:20 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux





Any help is highly appreciated!

Thank you and best,

Mohammad
