Hi,
I have this program:
#define N 100
int main()
{
int x[N], y[N];
for (int i = 0; i < N; i++) {
y[i] = 1;
x[i] = 1;
}
#pragma omp target teams distribute parallel for
for (int i = 0; i < N; i++){
y[i] += x[i];
}
}
Compile and run in this way:
$ clang -fopenmp -fopenmp-targets=x86_64-unknown-linux-gnu test.c -lomptarget
$ OMP_THREAD_LIMIT=8 OMP_TARGET_OFFLOAD=DISABLED ./a.out
OMP: Warning #96: Cannot form a team with 80 threads, using 8 instead.
OMP: Hint Consider unsetting KMP_DEVICE_THREAD_LIMIT (KMP_ALL_THREADS), KMP_TEAMS_THREAD_LIMIT, and OMP_THREAD_LIMIT (if any are set).
Segmentation fault (core dumped)
I get the warning, but why does the runtime aborts?
Is this situation described in the Spec? I could not find anything specific.
I am using Clang/LLVM/OpenMP 8.0.1.
Thanks.
Simone
