Hi,

I would like to ask a question about using icc to compile
IntelMPITEST-1.0
and run the program in heterogeneous environment.

I have a i386 node and a x86_64 node.
I have configed and compiled IntelMPITEST-1.0 testsuite at the i386
node.
I run the testsuite in the i386 node, and use "mpirun -machinefile" to
run
the binary on both nodes.

I have tried the test with gcc and pgi compilers, they work.
But for icc8, I have encounter error in
c/blocking/functional/MPI_Ssend_ator

The error message is very long, but has similar pattern like:

MPITEST error (3): i=0, long double value= -0.0000000000, expected
0.0000000000
MPITEST error (3): 10 errors in buffer (3,0,13) len 8 commsize 4
commtype -10 data_type 13 root 3
MPITEST error (3): Send/Receive lengths differ -
Sender(node/length)=0/8, Receiver(node/length)=3/-32766
MPITEST error (3): i=0, long double value= -0.0000000000, expected
0.0000000000
MPITEST error (3): 117 errors in buffer (4,0,13) len 83 commsize 4
commtype -10 data_type 13 root 3
MPITEST error (3): Send/Receive lengths differ -
Sender(node/length)=0/83, Receiver(node/length)=3/-32766

All the errors are related to data_type 13 and 14.
This error does not happen when I run the tests on 2 i386 nodes.

Have you any idea on the problem? Thank you.

PS.
I find that the error message is produced from "libmpitest.c" line 2361.

And I find that one of the many compilation warning is related to the
line
./libmpitest.c(2361): warning #181: argument is incompatible with
corresponding format string conversion
i, ((derived1 *)buffer)[i].LongDouble[k],

May be it's related, I am not sure.
