Hi,
today I tried to use a subarray data type in MPI-IO. But all I got was
the error message:
Error: Unsupported datatype passed to ADIOI_Count_contiguous_blocks
In the LAM mailing list archives I read in a post from 2003 that the
error is originated by ROMIO and it is because LAM treats
MPI_Type_darray and MPI_Type_subarray as first-class MPI-2 derived
datatypes, whereas ROMIO assumes that these are built on top of MPI-1
derived datatypes and this needs to be fixed in ROMIO.
At the moment I am using LAM/MPI 7.0.6. Is there any chance that the
problems with MPI_Type_darray and MPI_Type_subarray will be fixed in
future LAM/MPI versions or Open-MPI?
