    Where can I found the ACML release for GPU?


      Does the latest release ACML 4.1 support AMD stream computing? when will the AMD release for GPU launch? Is there any BLAS library already support AMD stream computing? Thanks for any feed back.

            hi,I build the linpack with the lib of acml_gpu in AS 5u1,mpich-1.2.7, the linker say wrong,the message show as follow:

            /root/acml-gpu/acmlg1.0/gfortran64/lib/libacml.a(ompaaw.o): In function `ompaawg_':

                Hello Haikuo,

                Please follow the example for linking in acmlg1.0/gfortran/examples/makefile.

                The command line for the linker must include libCALBLAS as well as libacml.

                Here is the log from building the samples:
