<div style="direction:ltr; font-family:Tahoma; color:#333399; font-size:10pt">Hi,<br>
<br>
I have a trace of an MPI program in which parameters of every MPI calls have been recorded. Some communication functions are using a user-defined type created with MPI_Type_create_darray.
<br>
<br>
I would like to know what is the size of this type as a function of the parameters passed to MPI_Type_create_darray (again, I'm working on a trace, so I can't just call MPI_Type_size). We can assume, for simplicity, that the oldtype parameter is MPI_BYTE. I'm
having troubles understanding, from the standard and from online documentation, how this function works and how I can compute this size. Could you help?<br>
<br>
Thanks,<br>
<br>
Matthieu<br>
