Force single Precision Calculation for Cuda

Post by Dominic » Thu Jan 05, 2017 8:51 am

Hi, I would like to use the single precision calculation for GPU in Abinit, however, I get an error running with

Code: Select all

use_gpu_cuda


This is the error Message

Code: Select all

--- !ERROR
src_file: invars0.F90
src_line: 431
mpi_rank: 0
message: |
    Input variables use_gpu_cuda is on but abinit hasn't been built
       with (double precision) gpu mode enabled !
       Action : change the input variable use_gpu_cuda
                or re-compile ABINIT with double-precision Cuda enabled.


Can somebody help me force single precision?
