Hi, I am currently preparing a benchmark for comparing FLENS with Gmm++.
As a first example I would like to compare 1) initializing a sparse matrix 2) computing the residual (where vectors are dense)I already started to compare FLENS with uBLAS. In a first test the matrix was initialized row-wise:
http://flens.sourceforge.net/session2/tut6.html
in a second test row and column indices were chosen randomly:
http://flens.sourceforge.net/session2/tut7.html
I attached a first version for a benchmark test case (were the matrix
gets initialized row-wise). In a first
test the results were not so good. So maybe you can give me a hint
how to improve the code in order to
get a fair comparison. As compiler-flags I usedg++ -DNDEBUG -ftemplate-depth-50 -funroll-loops -O3 -Wall -I/cluster/ include -I . -o ex_residual ex_residual.cc
I will perform the benchmarks on a Linux System with Opteron processors (see above links).
Thanks, Michael
