Should ADMM have decent accuracy?
so the answer depends upon how many digits of accuracy you want
and how many iterations you perform
but I would default to published papers on this
nevermind
I broke the build overzealously committing a fix for the Intel compilation issue
a fix is imminent (t-minus less than five minutes)
e.g.,
auto AView = A(ALL,ALL); AView = B;
views cannot be resized
at least not larger
they can't reallocate
But, i'll try the view thing.
I would recommend putting together a Minimum Working Example if you think otherwise
Riddle me this, what is wrong with this code?!?
#include <iostream>
#include <sstream>
namespace foo {
struct Rectangle { double height, width; };
std::ostream& operator<<(std::ostream& os, const Rectangle& a) { return os; }
inline void BuildStream(std::ostringstream& os) { }
template<typename T, typename... Args>
inline void BuildStream
(std::ostringstream& os, const T& item, const Args& ...args) {
os << item;
BuildStream(os, args...);
}
} // namespace foo
namespace bar {
using Rectangle = foo::Rectangle;
inline void BuildStream(std::ostringstream& os) { }
template<typename T, typename... Args>
inline void BuildStream
(std::ostringstream& os, const T& item, const Args& ...args) {
os << item;
BuildStream(os, args...);
}
} // namespace bar
int main(int argc, char* argv[]) {
std::ostringstream os;
bar::BuildStream(os, 1, 2);
bar::BuildStream(os, bar::Rectangle(), bar::Rectangle());
return 0;
}
the story Koenig tells in his blog post on Dr. Dobbs gives that away
but I am surprised no preference is given to the current namespace
Recent versions of CMake's
ExternalProject_Add create directories in the install folder during the configure stage
so cmake no longer works if you don't have elevated privileges?
and if someone manages to create malware inside of cmake tests, does that make cmake a virus?
so the privilege issue only applies if the user selected an installation location that required said privileges
but I honestly completely agree that rickety code that no one ever reads would be a great place to slip in something devious
there is now significant progress towards the inter-block chase: https://github.com/elemental/Elemental/blob/master/src/lapack_like/spectral/HessenbergSchur/MultiBulge/Dist/InterBlockChase.hpp
Intel 17.0.1 (20160921) builds Elemental cleanly, at least without QUAD support. I expect it will be released pretty soon, based upon the important bugfixes it contains. The historical trend is that update 1 drops in October or November (https://software.intel.com/en-us/articles/intel-compiler-and-composer-update-version-numbers-to-compiler-version-number-mapping).
Thanks for sharing that! It is definitely good news.
