On Cray systems the MPI constant MPI_REQUEST_NULL resolves to 738197504<br>but passing this value into nonblocking.c results in an error: <br><br>Error: no such request ID = 738197504<br><br><br>I think that this is an error in parallel-netcdf ncmpii_wait. <br>
<br>On the ibm aix system MPI_REQUEST_NULL resolves to -1 and nonblocking.c seems to handle it correctly.<br><br clear="all"><br>-- <br>Jim Edwards<br><br><font>CESM Software Engineering Group<br>National Center for Atmospheric Research<br>
