Runtime memory error: Crash due to insufficient memory
@all I was running the SPT program on my local Desktop at the university and it crashed due to insufficient memory. This was caused by a known Fortran issue where the program tries to allocate large arrays in the stack of the memory. Typically the stack is much smaller then the other part of the memory, the heap. So it runs our of memory way to soon. I was compiling with Fakhers configure.sh options using ifort. I could tell the compiler to allocate arrays larger then in the heap instead of the stack by adding the flag -heap-arrays .
