Thank you very much Max Horn, and Dr. Lübeck, for this information. I have two further questions:
1. Mac OS X 10.6.3 (Snow Leopard) is 64-bit ready, I believe.
So where can I obtain a 64 bit version of GAP? I cannot find it
on the official GAP site.
2. The GAP manual doesn't explain very well how one understands
the output of profiling functions. The output uses keywords, which seem
to refer to internal GAP functions, their number of calls etc., but could
someone please explain in greater detail how one understands the
output. For example, what do self/ms and chld/ms refer to? What do
the keyword InfoLevel and SHALLOW_COPY_OBJ refer to?
count self/ms chld/ms function
15029 16 8 IS_SSORT_LIST
10656 23 4 InfoLevel
14819 33 4 SSortedList
21586 37 0 APPEND_LIST
10446 36 7 AsSSortedList
13531 40 3 IntersectSet
23006 36 8 ADD_LIST
14679 47 0 SHALLOW_COPY_OBJ
102626 157 0 LENGTH
29072 147 35 Size
619 TOTAL
Sincerely, Sandeep.
