|Abstract:|| In this work we analyze an open-source multifrontal solver implementation (UMF-PACK) and modify it to transfer the computation load on an OpenCL device, typically a GPU. To achieve this result the dbOpenCL library has been created,
which allows a neat integration of OpenCL code into existent C or C++ code. An analysis and proling of both the original and the modied UMFPACK implementation is given while solving an example problem built with the LifeV finite element library.
