cs61-lectures/net8 directory contains a program called
matrixmultiply (source in
matrixmultiply.cc). This program creates
two random square matrices, multiplies them together, prints some
information about their product, then exits.
Can you use the knowledge you’ve gained in the class to radically
matrixmultiply, while producing (almost) exactly the same
results as the original for all arguments?
Note 1: You can copy
matrixmultiply.cc into other filenames; for
instance, given a file like
matrixmultiply-magic.cc, the makefile
will generate binaries like
Note 2: Docker overheads can overwhelm some performance improvements for this exercise. Try running outside Docker if you can.
