<tt>Hi Jeff,</tt>
<div class="moz-forward-container"> <tt>Thanks for your answer!</tt><br>
<tt>I changed to MPI_Waitsome. During that, I run into another
issue:</tt><br>
<tt>MPI_Waitsome raises a Segmentation fault, depending on the
order in which the requests are passed in, if different types of
requests are used (file and p2p).</tt><br>
<tt><br>
Here is the code:<br>
<br>
#include <iostream><br>
#include <mpi.h><br>
<br>
int main(int argc, char** argv)<br>
{<br>
MPI_Init(&argc, &argv);<br>
<br>
int rank;<br>
MPI_Comm_rank(MPI_COMM_WORLD, &rank);<br>
<br>
MPI_Request recv_req;<br>
int int_buf = 0;<br>
MPI_Irecv(&int_buf, 1, MPI_INT, MPI_ANY_SOURCE, 0,
MPI_COMM_WORLD, &recv_req);<br>
<br>
MPI_File fh;<br>
MPI_File_open(MPI_COMM_WORLD, "output", MPI_MODE_CREATE |
MPI_MODE_RDWR,<br>
MPI_INFO_NULL, &fh);<br>
<br>
MPI_Request file_req;<br>
double data = 42;<br>
MPI_File_iwrite_at(fh, rank*sizeof(double), &data, 1,
MPI_DOUBLE, &file_req);<br>
<br>
//MPI_Request requests[2] = {recv_req, file_req}; // A<br>
MPI_Request requests[2] = {file_req, recv_req}; // B<br>
std::cout << rank << ":\twaiting..." <<
std::endl;<br>
int completed = 0;<br>
int indices[2];<br>
MPI_Status status[2];<br>
MPI_Waitsome(2, requests, &completed, indices, status);<br>
// int index = 0;<br>
// MPI_Waitany(2, requests, &index, MPI_STATUS_IGNORE);<br>
std::cout << rank << ":\tdone" <<
std::endl;<br>
MPI_File_close(&fh);<br>
MPI_Finalize();<br>
<br>
return 0;<br>
}<br>
<br>
Exchanging line B with line A does not raises the fault.<br>
<br>
Thanks,<br>
Nils<br>

<div>I didn't determine for sure if it is the cause, but
MPI_Waitall, MPI_Wait, and MPI_Waitsome all invoke
MPI_Grequest progress, whereas MPI_Waitany does not, and I
recall that ROMIO uses generalized requests.</div>

<div class="h5">Dear MPICH community,<br>
<br>
I'm currently playing around with the File-IO
interface of MPI. For any<br>
reason, the following code does not running
through:<br>
<br>
#include <iostream><br>
#include <mpi.h><br>
<br>
int main(int argc, char** argv)<br>
{<br>
MPI_Init(&argc, &argv);<br>
<br>
int rank;<br>
MPI_Comm_rank(MPI_COMM_WORLD, &rank);<br>
<br>
MPI_Request recv_req;<br>
int int_buf;<br>
MPI_Irecv(&int_buf, 1, MPI_INT,
MPI_ANY_SOURCE, 0, MPI_COMM_WORLD,<br>
&recv_req);<br>
<br>
MPI_File fh;<br>
MPI_File_open(MPI_COMM_WORLD, "output",
MPI_MODE_CREATE | MPI_MODE_RDWR,<br>
MPI_INFO_NULL, &fh);<br>
MPI_File_set_view(fh, 2*sizeof(int)*rank,
MPI_INT, MPI_INT,<br>
"native", MPI_INFO_NULL);<br>
<br>
MPI_Request file_req;<br>
MPI_File_iwrite(fh, &rank, 1, MPI_INT,
&file_req);<br>
<br>
MPI_Request file_req2;<br>
MPI_File_iwrite(fh, &rank, 1, MPI_INT,
&file_req2);<br>
<br>
MPI_Request requests[2] = {file_req,
file_req2};<br>
int index;<br>
std::cout << rank <<
":\twaiting..." << std::endl;<br>
MPI_Waitany(2, requests, &index,
MPI_STATUS_IGNORE);<br>
//MPI_Wait(&file_req,
MPI_STATUS_IGNORE);<br>
std::cout << rank << ":\tdone"
<< std::endl;<br>
MPI_File_close(&fh);<br>
<br>
MPI_Finalize();<br>
<br>
return 0;<br>
}<br>
<br>
Neither if i exchange file_req2 with recv_req,
MPI_Waitany doesn't return.<br>
<br>
Is it possible to use MPI_Waitany with File-IO
calls? Did i read<br>
anything over in the MPI-Standard?<br>
<br>
Thank you for your help.<br>
<br>
Thanks,<br>
Nils<br>
