Problem with hpcc, intel mpi and intel mkl: PTRANS failed

Hi,

We have a little cluster (4 nodes; each node 12 cores). I'm trying to test hpcc on it. So I have read:
http://origin-software.intel.com/en-us/articles/performance-tools-for-software-developers-use-of-int...
and have done step by step the things. My make.arch is:

It compiles without error. Then I take the input file and starts the program with mpirun -np 4 hpcc on our master. I get:
mpirun -np 8 hpcc

An explanation of the input/output parameters follows:
T/V : Wall time / encoded variant.
N : The order of the coefficient matrix A.
NB : The partitioning blocking factor.
P : The number of process rows.
Q : The number of process columns.
Time : Time in seconds to solve the linear system.
Gflops : Rate of execution for solving the linear system.

The following parameter values will be used:

N : 10240
NB : 128
PMAP : Row-major process mapping
P : 2
Q : 4
PFACT : Right
NBMIN : 4
NDIV : 2
RFACT : Crout
BCAST : 1ringM
DEPTH : 1
SWAP : Mix (threshold = 64)
L1 : transposed form
U : transposed form
EQUIL : yes
ALIGN : 8 double precision words

- The matrix A is randomly generated for each test.
- The following scaled residual check will be computed:
||Ax-b||_oo / ( eps * ( || x ||_oo * || A ||_oo + || b ||_oo ) * N )
- The relative machine precision (eps) is taken to be 2.220446e-16
- Computational tests pass if scaled residuals are less than 16.0

So it seems to bug into PTRANS. How can I solve this problem ?
Thx a lot,

I did a mistake:
I just copy the make.UNKNOWN from the hpl setup. I f I modify the -DF77_INTEGER=int into -DF77_INTEGER=long, the PTRANS test runs without problem.

Now I get a *** glibc detected *** hpcc: free(): invalid pointer: 0x0000003647952a88 *** a the beginning of StarFFT section.
Any Ideas ?

Hi,

I suggest that you change LAdir in order to move the fftw2x wrapppers before the MKL interface library like this:

LAlib = $(LAdir_local)/libfftw2x_cdft_DOUBLE.a $(LAdir_local)/libfftw2xc_intel.a $(LAdir)/libmkl_solver_ilp64.a -Wl,--start-group $(LAdir)/libmkl_intel_ilp64.a $(LAdir)/libmkl_intel_thread.a $(LAdir)/libmkl_core.a $(LAdir)/libmkl_blacs_intelmpi_ilp64.a $(LAdir)/libmkl_cdft_core.a -Wl,--end-group -openmp -lpthread

The reason behind this is that MKL's interface layer (i.e. libmkl_intel_ilp64.a) contains pre-built FFTW3 wrappers and their implementations of fftw_free() are not compatible with FFTW2 used by HPCC.

Best regards,
-Vladimir
