Content-Type: text/plain; charset=us-ascii Sender: owner-linuxppc-dev@lists.linuxppc.org List-Id: I am currently benchmarking FFTs on our SMP box (Synergy VSS4 G4 400 MHz - Linux 2.2.18) using two different libraries. One is FFTW, and the other is an AltiVec-enabled library I downloaded from the Apple Developer's website. Both libraries run as expected on a PowerMac G4 running Linux 2.2.17. Both libraries run as expected on the SMP machine using the uniprocessor kernel . The FFTW library runs as expected on the SMP machine using the SMP kernel. However, when I use the AltiVec FFT library on the VSS4 with the SMP kernel, the results are corrupted. Is there still an AltiVec bug in the SMP kernel? Thanks in advance, Matthew Karger Sr. Student Associate Applied Research Laboratory The University of Texas at Austin karger@arlut.utexas.edu ** Sent via the linuxppc-dev mail list.
