- added g_gpu_per_node = number of GPUs per node; can be set as input parameter;
- in invert_dw_quda: if g_gpu_per_node is zero, the QUDA function getGpuCount will be called
- added switch statement to choose which QUDA inverter interface function to call
- fixed bug in xchange_field_5d: lenght of request field too small, changed to 1025
- changed the output format of the backward amplitude to re and im for all times (like for the forward amplitude)
implemented safety measure for case when OPENMP is undefined but g_num_threads is set to value larger than
1 in the input file; g_num_threads is the reset to 1 after the input file was parsed
