Open discussion for MAGMA library (Matrix Algebra on GPU and Multicore Architectures)
I tested function sgesvd using program testing_sgesvd.cpp. The result seems to indicate there is not much improvement for GPU over the CPU version. I also tried the same function from CULA library, the speedup is very dramatic. I wonder if there is something wrong with this function in Magma?

Thanks for this note. There are a few components of the gesvd that we have accelerated in MAGMA but don't use yet in the magma gesvd. Right now we only use the bi-diagonalization that is about 10x faster than MKL on multicore CPUs (depending on machine and matrix sizes). The other GPU-accelerated components will be added in MAGMA 1.1 that will be released for SC11.
