Mixed-Precision Computing for Scientific Discovery: Formats, Co-Design, and Responsible Approximation
Emmanuel Agullo, Hartwig Anzt, Daniel Bauer +37
Reduced and mixed precision have moved from a niche optimization to a central design axis in scientific computing and engineering, driven by energy constraints, heterogeneous accel…
Accelerating MPGP-type Methods Through Preconditioning
Jakub Kružík, David Horák
This work investigates the acceleration of MPGP-type algorithms using preconditioning for the solution of quadratic programming problems. The preconditioning needs to be done only…
On the parallel solution of hydro-mechanical problems with fracture networks and contact conditions
Jan Stebel, Jakub Kružík, David Horák +2
The paper presents a numerical method for simulating flow and mechanics in fractured rock. The governing equations that couple the effects in the rock mass and in the fractures are…
Active set expansion strategies in MPRGP algorithm
J. Kruzik, D. Horak, M. Cermak +2
The paper investigates strategies for expansion of active set that can be employed by the MPRGP algorithm. The standard MPRGP expansion uses a projected line search in the free gra…
