Hi Edgar,
Yeah I finally figured out that by MPI_2DOUBLE_COMPLEX they didn't
mean it was two doubles side my side (real and imag) to make a
complex. Once I sorted things out with MPI_DOUBLE_COMPLEX it seems to
work great. Thanks!

Hi Don,
Somehow I thought it might not be so easy.. otherwise it might have
been spotted before!
Although we first spotted the problem with our own application, I did
the most recent tests using the Intel MPI Benchmarks
(intel_clustertools3.tar.gz) and saw the same behaviour. It might be

you are probably using the wrong data type. MPI_2DOUBLE_COMPLEX is like
a structure of two 'double complex' data types for MPI_MINLOC/MAXLOC
operations in MPI_Reduce/Allreduce.
You should try MPI_DOUBLE_COMPLEX. Resp, if this still doesn't work,
compare the size of your complex data type from
Hi everyone,
An interesting problem I've discovered with MPI_Read_file (part of the
MPI I/O interface). When trying to read a 256^3 complex array (by
complex I mean "complex" defined in complex.h) into a single
dynamically allocated array (whos memory is successfully allocated).
To read I call:
M
