@yosefe I do not know if there is a way just remove the lock/unlock. However, I tried using `MPI_Win_fence` on the place and It did not work.

Here the new code ```c++ #include #include #include #include #include #include int main(int argc, char *argv[]) { int id, comm_sz; int prov; MPI_Init_thread(&argc, &argv, MPI_THREAD_SERIALIZED, &prov); MPI_Comm_rank(MPI_COMM_WORLD, &id); MPI_Comm_size(MPI_COMM_WORLD, &comm_sz);...

Hello everyone, thanks for the help. A few days ago, I managed to solve it using the following sequence of commands ``` $ salloc --exclusive --hint=compute_bound -N2 mpirun --mca btl_openib_allow_ib...

@devreal, PR #10554 does not solve my problem. I've done the checkout and installed your branch `osc-ucx-rputget-flushnb-v5.0.x`, but it did not work. I was reviewing my tests and I think...

@devreal , I was checking and, in fact, the network adapter (mxl4) that I am using seems not to have this technology. However, I continue confuse about why the code...

@janjust Yes, in both cases I used the same environment. Runing with `mpirun --mca osc rdma -mca btl_openib_allow_ib 1 -mca btl_openib_if_include mlx4_0:1 ./bin/sync.o` ``` ID 0 Start TASK 0 ID...
