  • The following fix works fine. The fix has been provided by John Moyart from CNES, France. It works great for all who have tried it.

replaced Mptr() definition:
  #define    Mptr( a_, i_, j_, lda_, siz_ ) \ ( (a_) + ( ( (i_)+(j_)*(lda_) )*(siz_) ) )
by:
  #define    Mptr( a_, i_, j_, lda_, siz_ ) \ ( (a_) + ( (off_t) ( (off_t)(i_)+(off_t)(j_)*(off_t)(lda_))*(off_t)(siz_) ) )
  • Other fix: compile scalapack using 64-bit integers
