} - сейчас для двух процессов запускаю через mpiexec - но для двумерного случая выгоднее использовать 4 процесса - где каждый процесс будет вычислять на своей развертке - верхней/нижней/левой/правой - тогда только нулевой процесс также будет взаимодействовать с интерфейсом и считать, а остальные 3 процесса будут независимо считать, наилучший обмен данными будет когда каждый будет рассылать свои лучшие значения каждому, также придётся модифицировать функции extern "C" __declspec(dllexport) __declspec(noalias) __forceinline void AgpWaitStartAndRun() noexcept
{
int dummy;
float* __restrict buf;
size_t len;
while (true) {
if (g_world->iprobe(0, 0)) {
g_world->recv(0, 0, dummy);
AGP_2D(2.0f, 10000.0f, -2.2f, 1.8f, -2.2f, 1.8f, 2.5f, false, 0.00001f, GetTickCount(), &buf, &len);
}
}
}

extern "C" __declspec(dllexport) __declspec(noalias) __forceinline void AgpStartWorkers() noexcept
{
g_world->isend(1, 0, 0);
} - первая функция останется без изменений, так как сигнал о старте также будет исходить от нулевого процесса, но вторую функцию придётся модифицировать - так как отправлять этот сигнал придётся всем остальным трём процессам, сделай эти изменения - и приведи полный модифицированный код для всех файлов - также учти что важна максимальная скорость - так что если возможно используй все возможные оптимизации (как у меня например вычисление ранга партнёра через битовые операции), ещё придётся заменить условие (если партнёр) на (если ранг == 0) так как теперь будет больше процессов, приведи полный код - думай как можно дольше чтобы дать лучший ответ, код должен быть максимально оптимизированным и быстрым
