Using Performance Forecasting to Accelerate Elasticity
Cloud computing facilitates dynamic resource provisioning. The automation of resource management, known as elasticity, has been subject to much research. Monitoring of a running service plays a crucial role, and adjustments are made when certain thresholds are crossed. On such occasions, it is common practice to simply add or remove resources. In this paper we ask ourselves how we can predict t...
متن کاملHigh Performance Computing Using Out-of- Core Sparse Direct Solvers
In-core memory requirement is a bottleneck in solving large three dimensional Navier-Stokes finite element problem formulations using sparse direct solvers. Out-of-core solution strategy is a viable alternative to reduce the in-core memory requirements while solving large scale problems. This study evaluates the performance of various out-of-core sequential solvers based on multifrontal or supe...
متن کاملUsing Sequential Unconstrained Minimization Techniques to simplify SVM solvers
In this paper, we apply Sequential Unconstrained Minimization Techniques (SUMTs) to the classical formulations of both the classical L1 norm SVM and the least squares SVM. We show that each can be solved as a sequence of unconstrained optimization problems with only box constraints. We propose relaxed SVM and relaxed LSSVM formulations that correspond to a single problem in the corresponding up...
متن کاملUsing Synthesis Techniques in SAT Solvers
In many application domains in VLSI CAD, like formal verification or test pattern generation, the problem to be solved can be formulated as an instance of satisfiability (SAT). The SAT instance in this cases is usually derived from a circuit description. In this paper we propose to use techniques known from logic synthesis to speed up SAT solvers. By experiments it is shown that these technique...
متن کاملComparison of Some High-Performance MINLP Solvers
In this paper some high-performance mixed integer non-linear programming (MINLP) solvers in GAMS (General Algebraic Modeling System) are evaluated. AlphaECP, Baron, Dicopt and SBB are the MINLP (mixed integer non-linear programming) solvers in focus. A large test set with 250 problems is used and special attention is given to a new GAMS solver, GAMS/AlphaECP, which has recently been included in...
