Hi, Thanks for your reply and nice advice. I'll try it and report then. Best regards, Cho

Hi, I am new to ViennaCL and am applying ViennaCL our simulator. The simulator has own CSR matrix and I did firstly convert it to viennacl::compressed_matrix on CPU. After that, I'm using the function copy() like viennacl::copy(viennacl::compressed_matrix_cpu, viennacl::compressed_matrix_gpu). Then I got a following error, "void viennacl::copy(const viennacl::compressed_matrix<double,lu>&, viennacl::compressed_matrix<double,lu>& ) is ambiguous." Should I build from ublas::compressed_matrix on CPU...
