qbsolv convergence characteristics

[csharma]

Hi Guys,

Got qbsolv to build on windows just like the ree bsdbuild.

I'm facing a problem with qbsolv. qbsolv on windows command line doesn't converge when given the same input file as on free bsd on the mac.

Source is the same for both file streams and the only difference is the compiler, one is g++ and the other is Visual Studio 14 2015. Wanted to know why this is the case, I'm trying the command line version of the tool.

Best regards,
Cartik

Hi Cartik, Can you supply the qubo file and the command line selection for the case? Regards, Mike

hi Mike,

I cannot share the .qubo file due to IP reasons. What compiler are you using to build qbsolv on windows? qbsolv converges fine for the same qubo file on the MAC.

Best regards,

Hi Carik I have only used gcc compile with full optimization on windows. On Mac and Linux the compilers are clang and/or gcc. Notice on Mac, when you ask for gcc you really get clang. On all platforms full optimization makes a big difference on performance. Clang has the best performance. Generally platform differences are due to random number generation. If you know what the “energy” result is you can specify that on the command line with the “target” value. Also the verbosity will allow you to watch the progress of the search. Mike

Are you using a Cygwin based enviroment to compile?

I personally have not compiled on windows in over 6 months, but at that time we used mingw, which is a bit more stripped down than cygwin. Mike
