My Desktop

Branch: master
Build Command: mvn clean install -Phadoop2
Built and tested successfully

Branch: andrewpalumbo/mahout/viennacl-opmmul-a
Bulid Command: mvn clean install -Pviennacl -Phadoop2 -DskipTests && mvn
test

Builds successfully-
Tests still riddled with

[INFO] Creating org.apache.mahout.viennacl.opencl.GPUMMul solver
[WARN] Unable to create class GPUMMul: attempting OpenMP version
[INFO] Creating org.apache.mahout.viennacl.openmp.OMPMMul solver
[INFO] Unable to create class OMPMMul: falling back to java version

Would be fixed with pom hack I presented earlier (developed hack on this
box)
