You typically edit these lines only once, to specify the modules. The following targets tell how to compile objects from sources. The merged files, showing pipeline statistics above the loops to which they apply, are written with .swp extensions. Note that the source line number the compiler assigns to a generated loop is only approximate because the higher levels of optimization transform the code. As a result, a report card in the .swp file sometimes precedes the loop to which it applies, although the report card sections appear in the correct sequence.
Output is a list of loop-files.
This script simplifies the run of a SpeedShop experiment. This script demonstrates one way to reduce and analyze the output of a perfex profile. Each line of input must be a list of numbers that represent execution times for one program using different numbers of CPUs. The script displays the calculated parallel fraction of the code, p , and the speedup and expected run time for various numbers of CPUs. This routine allows a program to pass the address of any variable, and recover the physical memory address of the page containing the variable.
