Is there some way, either within numpy or at build-time, to verify you're using BLAS/LAPACK? Is there one we should be using? ...Eric On Fri, 2006-06-02 at 11:19 -0600, Travis Oliphant wrote:

Just to be sure, what exactly is affected when one uses the slower algorithms when neither BLAS or LAPACK is installed? For sure it will affect almost every function in numpy.linalg, as they use LAPACK_lite. And I guess that in numpy.core the dot() function uses the lite numpy/core/blasdot/_dotblas.c routine? Any other numpy functions that are affected?
convolve could also be affected (the basic internal _dot function gets replaced for FLOAT, DOUBLE, CFLOAT, and CDOUBLE). I think that's the only function that uses dot internally.
In the future we hope to be optimizing ufuncs as well.
