set_rkeops_option: Set up a specific compile or runtime options of 'rkeops' in...

In rkeops: Kernel Operations on GPU or CPU, with Autodiff, without Memory Overflows

Description

The function set_rkeops_option allows to modify the value of a single specific rkeops options in R global options scope.

Usage

set_rkeops_option(option, value)

Arguments

option	string, name of the option to set up (see Details).
value	whatever value to assign to the chosen option (see Details).

Details

rkeops uses two sets of options: compile options (see compile_options()) and runtime options (see runtime_options()). These options define the behavior of rkeops when compiling or when calling user-defined operators.

With the function set_rkeops_option, you can set up a specific rkeops option among:

• rkeops compile options: rkeops_dir(not recommended),build_dir, src_dir(not recommended),precision, verbosity, use_cuda_if_possible, col_major(not recommended),debug'

• rkeops runtime options: tagCpuGpu, tag1D2D, tagHostDevice, device_id with a value that you provide in input.

To know which values are allowed for which options, you can check compile_options() and runtime_options().

Value

None
