  • Vienna vs uBLAS performance

    I successfuly ported my code from uBLAS to Vienna but the performance degraded. uBLAS: Elapsed time: 3' 22.833 sec Vienna: Elapsed time: 7' 38.710 sec The code is running on a CPU with 24 cores and they are all reported 100% busy by top. The differences in the code are minimal. The core of the algorithm is this: Vector gb1(numHidden); # ifdef USE_UBLAS noalias(gb1) =...

    Thanks, that worked.

    I forgot to mention a way to replicate the problem; just use: Mlp m; m = Mlp();.

  • MEMORY_NOT_INITIALIZED

    I am trying to port an application from uBlas to ViennaCL. I just replaced uBlas vectors and matrices with vienna::vector and vienna::matrix. I get an error during the initialization of a class that contains a matrix: struct Mlp { viennacl::matrix<double, viennacl::row_major> w1, w2; viennacl::vector<double> b1, b2; ... }; Just when initializing the structure...
