Hello, I have setup a (sparse) SDP problem where the solution is 289x289 with 67 sparse constraints. When trying to solve this problem with the ensmallen PrimalDualSolver, I receive the following error message:
error: arma::memory::acquire(): out of memory unknown location(0): fatal error in "sdp_nominal_test": std::bad_alloc: std::bad_alloc It appears that my problem is consuming too much memory which makes me wonder: How big a problem can the PrimalDualSolver handle? Has such a benchmark been established? As a bonus: Is there any way to solve this problem? Preliminary web searches give me little hope of a simple solution, but I am hopeful that there is something that someone on this list can point out. Here is my system configuration: Host OS: Linux 18.04 (though the application is running inside of a docker container based on 16.04) RAM: 16GB Processor: Intel Core i7-8750H CPU @ 2.20GHz × 12 Many thanks, -Joe Dinius
