The following examples are from the site. 2. 141592653589793238460_dp contains [ 12 ] Chapter 1 ! le. 1) return allocate(odd((N+1)/2)) allocate(even(N/2)) ! divide odd =x(1:N:2) even=x(2:N:2) ! conquer call fft(odd) call fft(even) ! 0])) ) Performance concerns It would be difficult to compare the performance of these programs. The time required to run a program can be influenced by many things outside of the inherent properties of the language: • Skilled Fortran and Python programmers could find optimizations at the code level • Optimizing compilers vary in quality • Underlying libraries (for example, numpy) could be substituted in and affect performance • Critical sections could be coded in a compiled language (for example, Cython) or even assembly language, yielding a major speedup without affecting most of the lines of code • The architecture of the machine itself could have an impact [ 14 ] Chapter 1 Software engineering concerns The question of how fast code runs is independent of the question of how long it takes to write, debug, and maintain.
0 A schematic of the processing would look as follows: [ 27 ] Using IPython for HPC Discussion While the parallel version is slightly longer (20 lines of code compared to 15), it is also faster, given enough processors. The intuitive reason is that the invocations of f are not queued up waiting for a single processor. With a single processor, the invocation of f(i) has to wait in line behind all the previous invocations of f(a) where 1 ≤ a < i, even though there is no dependency between them. The single processor is an unnecessary bottleneck.
An example will explain this. : Your new magic is ready to go: In [3]: %getBootDevice Out[3]: '\\Device\\HarddiskVolume1' Some observations are in order: • Note that the function is, for the most part, standard Python. systeminfo shell command. You can freely mix both standard Python and IPython in IPython. • The name of the function will be the name of the line magic. • The line parameter contains the rest of the line (in case any parameters are passed). • A parameter is required, although it need not be used.
