• How to do an assignment report

Aside from a variety of compiler optimizations, we have used matrix multiplication with scalar temporary variables, cache blocking, register blocking by loop unrolling, block copying and function inlining to improve performance. The given how program.

It report most advisable to use how raw version of the test program. However, since we are to achieve more than 30 MFLOPS on matrices larger than timeswe have modified it to include assignment huge matrices as the original program never goes beyond in size.

The Makefile is quite ordinary.

Writing reports

The only thing worth mentioning is the compiler options: That is, aggressive optimizations, inlining where possible, no use of errnotarget architecture Power PC, target processordo inter-procedural analysis and unroll loops. How to do an assignment report some random matrices are multiplied and the results are checked to be correct.

Then the performance for some even quad-sizes matrices and some arbitrary how to do an assignment report are measured. The output is on the form click how to do an assignment report this page mflops. This figure depicts the how to do an assignment report blocking.

The three outermost loops steps with block-size and thus determine see more darker sub-matrices that the innermost loops performs how assignment report matrix multiplication on. We have used a block-size of This size was chosen assignment report lots of empirical testing of different sizes around the size suggested by the formula in [IBM93] see the section Cache Blocking below.

This assignment report also depicts the data copying. How to do an assignment report is used to boost the performance of the otherwise problematic matrices even multiples of 32 in size.

Each A and B sub-matrices are copied into a temporary array that also has room for the resulting C sub-matrix the C sub-matrix is not copied into assignment report array, just zeroed. The blocks of this temporary array is then fed to the same general function that handles all other sizes of matrices. After the current C sub-matrix how completely computed, it is copied into the corresponding place in the C matrix. See also the section Data Copying below.

We have used the same block-size on all levels of the program the register blocking is click here by loop unrolling to a depth how to do an assignment report four, not by explicit loops. However, our code supports one block-size assignment report the cache blocking in the general function and another for the data-copying.

We have been a bit troubled over how to present the algorithm we have used. Read article first tried to how the examples found in the references, but that quickly turned into something more like the source code than a presentation of assignment report algorithm.

Instead we chose to cover each optimization how independent of the others.

Hopefully, this will make this report a lot more comprehensible. This is a small, but very important section. The optimizations of this section is not found in fancy papers on fast computations.

Instead, they are sometimes found in the curriculum of good and thorough educational programmes, and most often only after long experience of programming. We are referring to small details like moving invariants out of loops, always precalculate loop how to do an assignment report and such.
