Runtime error in the first example for the Memory Functions

Hello everyone,

While I was reproducing the result of the first example for the memory functions, a runtime error arose. Please find the source code 'Memory_func_ex1', and the corresponding given document by

Usage Examples for the Memory Functions (intel.com)

 

After I changing declaration part of the arrays A, B, and C, the code ran without errors. Please find the attached source code 'Memory_func_ex1_rev' of the revised version. 

 

So, I am wondering if this is really a bug in the given code, or I made something wrong.

The only things I changed from the given code are

- I do not use

INCLUDE 'mkl.fi'

- I chose the following for my 64bit system

INTEGER*8 MKL_MALLOC, MKL_CALLOC, MKL_REALLOC
INTEGER*8 ALLOC_SIZE, NUM, SIZE

 

Thank you very much.

What Runtime error are You talking about? Could you clarify? I see no runtime problem with this code example.  Running this code main.f90 with Memory_func_ex1.f90 call only, I see no problem.

Here are the logs :

$ ./a.out
DGEMM uses 232271624 bytes in 47 buffers
Peak memory allocated by Intel MKL memory allocator 0
bytes. Start to count new memory peak
After reset of peak memory counter
Peak memory allocated by Intel MKL memory allocator 0
bytes

Here, I switch on the verbose mode to show MKL version details:

$ export MKL_VERBOSE=1
$ ./a.out
MKL_VERBOSE oneMKL 2021.0 Update 3 Product build 20210617 for Intel(R) 64 architecture Intel(R) Advanced Vector Extensions 2 (Intel(R) AVX2) enabled processors, Lnx 2.20GHz lp64 intel_thread
