Compilation error

Hi

I am trying to compile the C programme which uses the MKL subroutine.

For example, mkl_scsrdia and mkl_scsrcoo,

but when I am trying to compile it,

I am getting error like this. It seems that I am not linking some path

or flags during the compilation.

icc one.c -L$MKLPATH -I$MKLINCLUDE -lmkl -liomp5 -lpthread

one.c -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lpthread -lsplas -lm -lmkl -lguide

nothing wordks, got error like this

CGEMM performance strangeness on Haswell CPUs vs. Sandy Bridge

Hi All

I have investigated the performance of the CGEMM algorithm using both my own sandy bridge CPU and my colleagues newer computer with a Haswell cpu. The calculation is measured as the number of complex multiply accumulate operations per second it can perform, here denoted as CMacs. I don't use any scaling and I don't add the the previous matrix, so I only calculate C = A * B.

The setup:

The number of Rows in A = 2^16

Number of columns in A = 16

Number of columns in B = 256

GCMacs = A_r * A_c * B_c / time * 1e-9

mkl_peak_mem_usage does not reset ?

Hello!

i am using mkl_peak_mem_usage to measure mkl memory usage and despite i use mkl_peak_mem_usage(MKL_PEAK_MEM_RESET) , the counters are not zero. For example : 

mkl_peak_mem_usage(MKL_PEAK_MEM_RESET) ; // reset peak

printf( "memory peak : %lld\n", mkl_peak_mem_usage(MKL_PEAK_MEM_RESET)  ); // print peak and reset again

// do some calculations

printf( "memory peak : %lld\n", mkl_peak_mem_usage(MKL_PEAK_MEM_RESET)  ); // print new peak and reset

  • MKL_Complex16 arrays for mathematical operations problems

    Hello everyone

    I am using icc compiler to deal with my mkl_complex16 arrays, i was trying out my mathematical formula that i want to implement on the mic... but i got these errors:

    essai.c(136): error: expression must have struct or union type
                    sum.real= sum.real+w.real*y_in.real[z+1][s+1];
                                              ^

    essai.c(137): error: expression must have struct or union type
                    sum.imag= sum.imag+w.imag*y_in.imag[z+1][s+1];
                                              ^

    Here is my code:

    2D convolution using VSL Conv

    Hi all,

    I'm wondering if anyone can help. I'm trying to calculate a 2d convolution of two square arrays f(x,y) and g(x,y) using the code below, which compiles and runs fine (no error messages), but does not give the correct output for h(x,y). Instead, all values of h[n] are unchanged (e.g. if initialized before attempting the convolution) except one "column" of the output, at x=0.

    I've scoured the examples included with MKL libraries, but can't spot anything different between my code and the minimal working examples of this type.

    Thanks,

    Phil

     

    CPARDISO error

    Hello,

    I'm trying to solve a SPD matrix with CPARDISO but it fails with the following error:

    *** Error in PARDISO  (     insufficient_memory) error_num= 10
    *** Error in PARDISO memory allocation: SOLVING_ITERREF_WORK_DATA, allocation of 1 bytes failed

    The matrix is of size 90 x 90, and I have up to 4 GB of free RAM before runing the job on 2 MPI processes.

    I'm attaching the program, can you reproduce this behavior on your side ?

    Thank you for your help.
