Re: Survey on mtl/itl usage

By data profiler I mean that it can accumulate information about 
floating-point data as the program runs, and print out a report which 
includes the number of each operation (+,-,*,/,pow(),sqrt() etc.)  and 
the number of them that were trivial etc. to the screen or a .csv file 
under user control.  It also accumulates lhs and rhs statistics 
separately. 

All this is useful for understanding how many of the FLOPs expended in 
your algorithm are contributing effectively to the solution of large 
matrix problems.  This knowledge may allow you to reformulate your 
algorithm or transform your data in order to maximise efficiency and/or 
speed.
