Hello all,
I am attempting to build OpenMPI with TSAN enabled (to TSAN-itize a
project that uses OpenMPI), and am finding that OpenMPI throws lots of
errors in TSAN (not surprising.) I am attempting to build OpenMPI with
the following blacklist:
src:*
However, I am still getting errors when I run mpiexec. I've reduced it
down to the following minimal example:
--
#include <thread>
#include <unistd.h>
static int my_pipe[2];
int main()
{
pipe(my_pipe);
std::thread([]() {
std::this_thread::sleep_for(std::chrono::seconds(1));
close(my_pipe[1]);
}).detach();
write(my_pipe[1], "Hello", 5);
std::this_thread::sleep_for(std::chrono::seconds(2));
return 0;
}
--
Even when I compile this with -fsanitize-blacklist=blacklist.txt, I
still get a warning about a race condition. Is there some way I can
silence this, preferably without patching OpenMPI? Is this a bug in
TSAN?
Kyle
