MPI_Scan-nodes

The MPI_Scan operation performes a prefix reduction on data distributed across the participating processes. First we vary over the nodes. This measurement can be compared with MPI_Reduce.

• Pattern: Collective varied over number of nodes.
• default values: 8 nodes, message length 256 units, max. / act. time for suite disabled/0.00 min.
• Max. allowed standard error is 3.00 %.

• Units: number, basetype 1 (MPI_INT), send-datatype 20: size 4 Bytes, extent 4 Bytes (user defined basetype 1 (MPI_INT)), receive-datatype 20: size 4 Bytes, extent 4 Bytes (user defined basetype 1 (MPI_INT))
