Hello,<br>
<br>
I used MPI_Win_free, and it returns error code: 45, Invalid MPI_Win. I<br>
checked all my code, but I still cannot find out where is the problem. I<br>
was wondering any one can give a suggestion?<br>
<br>
I defined win as<br>
MPI_Win win;<br>
<br>
in RMA, I create a sub communicator: MPI_FOR_WORLD<br>
MPI_Win_create(image_buff, 2*image_info->image_size*<u></u>sizeof(uint16),<br>
sizeof(uint16), MPI_INFO_NULL, MPI_FOR_WORLD, win);<br>
<br>
In other MPI_FOR_WORLD process:<br>
MPI_Win_create(MPI_BOTTOM, 0, sizeof(uint16), MPI_INFO_NULL,<br>
MPI_FOR_WORLD, win);<br>
<br>
I use MPI_Get, just as normal thing. no mem violation.<br>
<br>
free it as<br>
MPI_Win_free(&win);<br>
<br>
I still cannot figure out why it keeps saying MPI_Win_free failed. Thank<br>
you very much for any suggestions.<br>
<br>
