Diagnostic 15134: vectorization support: reference xxxx has unaligned access (Fortran)

Cause:

The vectorizer cannot safely use aligned loads or stores for this data access, either because the data are not aligned to an n-byte boundary in memory, or because the compiler does not know the alignment. The compiler must use unaligned memory accesses, which may be less efficient. The value of n depends on the targeted instruction set and corresponds to the width of the vector instructions: 16 for Intel® SSE, 32 for Intel® AVX and 64 for Intel® AVX-512 instructions.

  • Install old version product with an expired license

    Problem

    When install old version product you may receive invalid license error, although you have input a valid serial number.

    Resolution

    When old version products are no longer formally supported by our website, your cannot activate them through serial number anymore. However as a perpetual license, it is still valid to install the old version product. Instead of inputing a serial number, you need to select "Alternative way" to activate, and choose a License file to complete activation.
