Lapack getri fails when OMP_NUM_THREADS not exported

Postby balson » Thu Sep 29, 2011 7:14 am

Hello, I am using gotoblas2 with openmp enabled option in it. And lapack comes with it. When i execute my application, the function getri fails (or atleast does not return or hangs). When i export OMP_NUM_THREADS=1, it successfully executes. Is this a bug ? What is the connection between getri() and openmp? Why it hangs when OMP_NUM_THREADS not exported? Many thanks in advance :-)

What happens if you export it to 2? it fails, no?
Otherwise, indeed not sure from where that comes form.
You may want to forward the question to the gotoblas2 team.
