Are MKL ScaLAPACK and BLACS Thread Safe?

I have not found any documentation specifically addressing whether or not the MKL ScaLAPACK and BLACS libraries are thread safe (OpenMP). I did find the following from here:

"In order to run ScaLAPACK multi threaded, you cannot use MKL or ACML since their ScaLAPACK routines are not thread-safe. "

Thanks,
Nathan

Nathan,

MKL is a thread-safe. There in only ?lacon routine which is not thread-safe. Please refer to see more details follow the link :
