Question: does LoopPoint work with other threading libraries like std thread/pthread besides OpenMP?

[koshostanford]

for example I have a simple program using std thread:

// sum_B_threads.cpp
#include <iostream>
#include <thread>
#include <vector>
#include <algorithm>
#include <cstdint>

int main() {
    const int64_t N = 200000000LL;  // 2e8
    const unsigned T = 4;

    std::vector<std::thread> threads;
    std::vector<long long> partial(T, 0);

    auto worker = [&](unsigned tid) {
        const int64_t base = N / T;
        const int64_t rem  = N % T;                          // first 'rem' chunks get +1
        const int64_t size = base + (tid < rem ? 1 : 0);
        const int64_t start = tid * base + std::min<int64_t>(tid, rem) + 1;
        const int64_t end   = start + size - 1;

        long long s = 0;
        for (int64_t i = start; i <= end; ++i) s += i;
        partial[tid] = s;  // one slot per thread → no locking needed
    };

    threads.reserve(T);
    for (unsigned t = 0; t < T; ++t) threads.emplace_back(worker, t);
    for (auto &th : threads) th.join();  // wait for all threads to finish

    long long total = 0;
    for (auto s : partial) total += s;

    std::cout << "Sum 1..200000000 (4 threads): " << total << "\n";
    return 0;
}

and I get this error in the log in the attached file:
