Initializing ABT-IO
The following code shows how to initialize and finalize ABT-IO.
ABT-IO must be initialized after Argobots and finalized before it.
The abt_io_init
function takes the number of ES to create
for handling I/O operations. Alternatively, the abt_io_init_pool
function can be used to make ABT-IO use an Argobots pool that was
alread created.
#include <abt-io.h>
int main(int argc, char** argv)
{
// Argobots must be initialized, either with ABT_init
// or with margo_init, thallium::engine, or thallium::abt.
ABT_init(argc, argv);
// abt_io_init takes the number of ES to create as a parameter.
abt_io_instance_id abtio = abt_io_init(2);
// ABT-IO must be finalized before Argobots it finalized.
abt_io_finalize(abtio);
ABT_finalize();
return 0;
