Bug dgeqrf mkl_sequential

Bug dgeqrf mkl_sequential


There is a problem with the dgeqrf function in sequential with the last mkl. The intel_thread give me the same results as lapack 3.4.1,, but in the sequential version the matrix seems


I provide a small program and data file for you to confirm that. 

I use : ifort testdgeqrf.f90 -lmkl_sequential -lmkl_core -lmkl_intel_lp64

For more complete information about compiler optimizations, see our Optimization Notice.

the test requires DDG.txt file.
e.g: open(10,file='DDG.txt')
I see - ddg.log is attached. Is this those file?

Yes sorry, in fact i had trouble uploading a *.txt file, so i renamed it .log . It contains the matrix that fails for me !
