We are developing an object oriented code set "Bridge++" for simulation of lattice gauge theories.It aims to be an extensible, readable, and portable workbench while keeping sufficiently high performance in actual productive runs.This paper describes the status of two extensions.One is multi-threading with OpenMP in the recently released version 1.2.The other is a design to use arithmetic accelerator devices such as GPGPUs, which is still under developing version.Feasibility test is performed with OpenCL.
