      <description><![CDATA[ We have modified this KB to work around for a bug, the memory is allocated with malloc() and de-allocation with fftw_free()  in HPCC 1.3.1 and provided the patch to fix the same.  Please download and apply the patch and follow the steps in "Build FFTW C wrapper library".

      <description><![CDATA[ Hello,

I tested as guided including "Build FFTW C wrapper library" part.
But I still got error as following:

*** glibc detected *** ./hpcc: free(): invalid pointer: 0x0000003ce8352d48 ***
======= Backtrace: =========
/lib64/libc.so.6[0x3ce80722ef]
/lib64/libc.so.6(cfree+0x4b)[0x3ce807273b]
./hpcc[0x4cbb0a]

I am using Intel compiler 11.1.072 and corresponding MKL in the compiler directory.
Also MPI is 4.0.0.028.
I tried both HPCC1.4.1 and 1.3.1 with same error

Thanks ]]></description>

      <description><![CDATA[ I tried to build HPCC with MKL and msmpi on Windows. I'm using Intel Composer 2011.1.127 and MKL 10.3.1.127 in VS2010. I successfully built fftw2x_cdft_DOUBLE_ilp64.lib and fftw2xc_intel.lib for ilp64 interface.

I link HPCC with 

msmpi.lib
fftw2x_cdft_DOUBLE_ilp64.lib
fftw2xc_intel.lib
mkl_blacs_msmpi_ilp64.lib
mkl_cdft_core.lib
mkl_core.lib
mkl_intel_ilp64.lib
mkl_intel_thread.lib

When I use just two compiler flags /DUSING_FFTW /DMKL_ILP64, everything seems to work fine  (the only thing that annoys me that StarFFT gets very memory-consuming). I cannot use  /DMKL_INT=long /DLONG_IS_64BITS flags, when I build with these flags the code wouldn't start and the output message I get from HPCC is "No 64-bit integer type available". How do I fix it? And will the solution help me with memory consuming issues? ]]></description>

      <description><![CDATA[ you build fftw_cdft ilp64, but in the link section you pull in lp64 (not ilp64) for everything.
Could you update the instructions for the 12.0 compilers, intel mpi 4.0.1.007.
could you also include the LAinc parameter and CCFLAGS, etc.  Maybe you could post your hpl/Make.intel file.
Thanks,
Roger ]]></description>

      <description><![CDATA[ Hi Roger,

  The Make.intel is attached in the article attachments section above.

The LAinc and CCLAGS are 

LAdir        = $(MKL)
LAinc        = -I$(MKL)/include

CCFLAGS      = $(HPL_DEFS) -DASYOUGO -O2 -xSSE4.2 -ip -ansi-alias -fno-alias -DUSING_FFTW -DMKL_INT=long -L$MKL/lib/intel64 -I$MKL/include/fftw -L$MPI/lib64 -DLONG_IS_64BITS -DRA_SANDIA_OPT2 -DHPCC_FFT_235

We are in the process of updating this article to the latest version of Intel MKL, Compilers and MPI.

Thanks,
Vipin

      <description><![CDATA[ Roger,

 The article has been already updated with the a note in the

Step 4 - Building HPCC

•  Build MPI MKL FFTW library.

as 

Note: Please note that by setting the interface parameter to ilp64 we require to build the FFTW MPI wrappers which admit 64-bit parameters in their interface to match the calls from HPCC.  These 64-bit aware wrappers are not to be used with usual applications complying with traditional FFTW interfaces.  Please execute $make to see the full set of options.

      <description><![CDATA[ Vipin,

When I use MKL 10.3.7.256, StarFFT aborts with the following message:

fftw_die: DftiCompute returned error in fftwnd()

MKL 10.3.0.084 is fine, though. I am using the 11.1.073 compilers.


regards,
