Add new website for Polly
Use the content of the Polly wiki page[1] to create a new website. I do not yet
plan to officially promote this website, but it is already a solid base that we
can improve and peer review.

Hence for the users of Polly it is often necessary to +understand how Polly works internally. To get an overview of the different steps +taken during polyhedral compilation, we give a step by step example on how to +use the different Polly passes. For this we optimize a simple matrix +multiplication kernel. In case you look for a more automated way of executing +Polly, check out the pollycc tool in utils/pollycc.</p> + +The files used and created in this example are available <a +href="experiments/matmul">here</a>. + +<ol> +<li><h4>Create LLVM-IR from the C code</h4> + +Polly works on LLVM-IR. Hence it is necessary to translate the source files into +LLVM-IR. If more than on file should be optimized the files can be combined into +a single file with llvm-link. + +<pre class="code">clang -S -emit-llvm matmul.c -o matmul.s</pre> +</li> + + +<li><h4>Load Polly automatically when calling the 'opt' tool</h4> + +Polly is not built into opt or bugpoint, but it is a shared library that needs +to be loaded into these tools explicitally. The Polly library is called +LVMPolly.so. For a cmake build it is available in the build/lib/ directory, +autoconf creates the same file in +build/tools/polly/{Release+Asserts|Asserts|Debug}/lib. For convenience we create +an alias that automatically loads Polly if 'opt' is called. +<pre class="code"> +export PATH_TO_POLLY_LIB="~/polly/build/lib/" +alias opt="opt -load ${PATH_TO_POLLY_LIB}/LLVMPolly.so"</pre> +</li> + +<li><h4>Prepare the LLVM-IR for Polly</h4> + +Polly is only able to work with code that matches a canonical form. To translate +the LLVM-IR into this form we use a set of canonicalication passes. For this +example only three passes are necessary. To get good coverage on a larger set +of input files a larger set is needed. pollycc contains a set of passes that has +shown to be beneficial. +<pre class="code">opt -S -mem2reg -loop-simplify -indvars matmul.s > matmul.preopt.ll</pre></li> + +<li><h4>Show the SCoPs detected by Polly (optional)</h4> + +To understand if Polly was able to detect some SCoPs, we print the +structure of the detected SCoPs. In our example two SCoPs were detected.

Each benchmark was run with double precision floating +point values on an Intel Core Xeon X5670 CPU @ 2.93GHz (12 cores, 24 thread) +system. We used <a href="http://pocc.sf.net">PoCC</a> and the included <a +href="http://pluto-compiler.sf.net">Pluto</a> transformations to optimize the +code. The source code of Polly and LLVM/clang was checked out on +25/03/2011.</p> + +<p>The results shown were created fully automatically without manual +interaction. We did not yet spend any time to tune the results. Hence +further improvments may be achieved by tuning the code generated by Polly, the +heuristics used by Pluto or by investigating if more code could be optimized. +As Pluto was never used at such a low level, its heuristics are probably +far from perfect. Another area where we expect larger performance improvements +is the SIMD vector code generation. At the moment, it rarely yields to +performance improvements, as we did not yet include vectorization in our +heuristics. By changing this we should be able to significantly increase the +number of test cases that show improvements.</p> + +<p>The polybench test suite contains computation kernels from linear algebra +routines, stencil computations, image processing and data mining. Polly +recognices the majority of them and is able to show good speedup. However, +to show similar speedup on larger examples like the SPEC CPU benchmarks Polly +still misses support for integer casts, variable-sized multi-dimensional arrays +and probably several other construts. This support is necessary as such +constructs appear in larger programs, but not in our limited test suite. + +<h2> Sequential runs</h2> + +For the sequential runs we used Polly to create a program structure that is +optimized for data-locality. One of the major optimizations performed is tiling. +The speedups shown are without the use of any multi-core parallelism. No +additional hardware is used, but the single available core is used more +efficiently. +<h3> Small data size</h3> +<img src="images/performance/sequential-small.png" /><br /> +<h3> Large data size</h3> +<img src="images/performance/sequential-large.png" /> +<h2> Parallel runs</h2> +For the parallel runs we used Polly to expose parallelism and to add calls to an +OpenMP runtime library. With OpenMP we can use all 12 hardware cores +instead of the single core that was used before. We can see that in several +cases we obtain more than linear speedup. This additional speedup is due to +improved data-locality. +<h3> Small data size</h3> +<img src="images/performance/parallel-small.png" /><br /> +<h3> Large data size</h3> +<img src="images/performance/parallel-large.png" /> +</div> +</body> +</html> diff --git a/polly/www/publications.html b/polly/www/publications.html new file mode 100644 index 00000000000..afde2b1346a --- /dev/null +++ b/polly/www/publications.html @@ -0,0 +1,43 @@ +<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" + "http://www.w3.org/TR/html4/strict.dtd"> +<!-- Material used from: HTML 4.01 specs: http://www.w3.org/TR/html401/ --> +<html> +<head> + <META http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> + <title>Polly - Publications</title> + <link type="text/css" rel="stylesheet" href="menu.css"> + <link type="text/css" rel="stylesheet" href="content.css"> +</head> +<body> +<!--#include virtual="menu.html.incl"--> +<div id="content"> + <!--*********************************************************************--> + <h1>Polly: Publications</h1> + <!--*********************************************************************--> + + <h2> 2011 </h2> + <ul> + <li>Polly - Polyhedral Optimization in LLVM<br /> + Tobias Grosser, Hongbin Zheng, Ragesh Aloor, Andreas Simbürger, Armin + Größlinger, Louis-Noël Pouchet<br /> + IMPACT at CGO 2011 <br /> + <a + href="publications/grosser-impact-2011.pdf">Paper</a>, <a + href="publications/grosser-impact-2011-slides.pdf">Slides + </a> + </li> + </ul> + <h2> 2010 </h2> + <ul> + <li>Polly - Polyhedral Transformations for LLVM<br /> + Tobias Grosser, Hongbin Zheng<br /> + LLVM Developer Metting <br /><a + href="http://llvm.org/devmtg/2010-11/Grosser-Polly.pdf">Slides</a>, <a + href="http://llvm.org/devmtg/2010-11/videos/Grosser_Polly-desktop.mp4">Video + (Computer)</a>, <a + href="http://llvm.org/devmtg/2010-11/videos/Grosser_Polly-mobile.mp4">Video + (Mobile)</a></li> + </ul> +</div> +</body> +</html> diff --git a/polly/www/publications/grosser-impact-2011-slides.pdf b/polly/www/publications/grosser-impact-2011-slides.pdf Binary files differnew file mode 100644 index 00000000000..3e604108a8d --- /dev/null +++ b/polly/www/publications/grosser-impact-2011-slides.pdf diff --git a/polly/www/publications/grosser-impact-2011.pdf b/polly/www/publications/grosser-impact-2011.pdf Binary files differnew file mode 100644 index 00000000000..9b79bd26fa0 --- /dev/null +++ b/polly/www/publications/grosser-impact-2011.pdf diff --git a/polly/www/todo.html b/polly/www/todo.html new file mode 100644 index 00000000000..a8b589d3b62 --- /dev/null +++ b/polly/www/todo.html @@ -0,0 +1,363 @@ +<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" + "http://www.w3.org/TR/html4/strict.dtd"> +<!-- Material used from: HTML 4.01 specs: http://www.w3.org/TR/html401/ --> +<html> +<head> <META http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> + <title>Polly - Todo</title> + <link type="text/css" rel="stylesheet" href="menu.css"> + <link type="text/css" rel="stylesheet" href="content.css"> +</head> +<body> +<!--#include virtual="menu.html.incl"--> +<div id="content"> +<h3> Setup infrastructure at LLVM </h3> + +<p>We are currently moving to the LLVM infrastructure +</p> +<table class="wikitable" cellpadding="2"> + +<tbody><tr> +<th width="400px"> Task +</th><th width="150px"> Status +</th><th>Owner +</th></tr> +<tr> +<th align="left"> Move to LLVM svn +</th><td align="center"> done +</td><td> Tobias + +</td></tr> +<tr> +<th align="left"> Get git mirror at llvm.org/git/polly.git +</th><td align="center"> done +</td><td> Tobias +</td></tr> +<tr> +<th align="left"> Setup on commit mails +</th><td align="center"> +</td><td> Tobias +</td></tr> +<tr> + +<th align="left"> Add LLVM Bugzilla category +</th></tr> +<tr> +<th align="left"> Create polly.llvm.org website +</th><td> +</td></tr> +<tr> +<th align="left"> Add Polly buildbot that runs 'polly-test' +</th><td> +</td></tr> +<tr> +<th align="left"> Run nightly performance/coverage tests with the llvm +test-suite +</th><td> + +</td></tr> +</tbody></table> +<h3> Phase 2 </h3> +<p>The second phase of Polly can build on a robust, but very limited framework. +In this phase work on removing limitations and extending the framework is +planned.

All +basic blocks in the CFG that do not return are - at the moment - not part of the +post dominance tree. +However by adding some virtual edges, they could be added to the post dominator +tree. Where to add the edges needs some research. +</p><p>This is a small project, that is is well defined. As it is directly in +LLVM it can be easily committed upstream. It is useful for polly, as the +RegionInfo pass will be able to detect regions in parts of the CFG that never +return. +</p><p><i>A good starter to get into LLVM</i> +</p> +<h4>Vectorization </h4> +<p>It is planned to use Polly to support vectorization in LLVM. +</p><p>The basic idea is to use Polly and the polyhedral tools to transform code +such that the innermost loops can be executed in parallel. Afterwards during +code generation in LLVM the loops will be created using vector instructions. +</p><p>To start we plan to use <a href="http://pluto-compiler.sf.net" +class="external text" title="http://pluto-compiler.sf.net" +rel="nofollow">Pluto</a> to transform the loop nests. Pluto can generate vector +parallel code and annotate the vector parallel loops. Some impressive results +were shown on code that was afterwards vectorized by the icc enforcing +vectorization. We believe LLVM can do even better, as it can interact directly +with the polyhedral information. + +</p><p>As an example simple matrix multiplication: +</p> +<pre> +for(i=0; i<M; i++) + for(j=0; j<N; j++) + for(k=0; k<K; k++) + C[i][j] = beta*C[i][j] + alpha*A[i][k] * B[k][j]; +</pre> +<p>After plutos transformations with added tiling and +vectorization hints: +</p> +<pre> +if ((K >= 1) && (M >= 1) && (N >= 1)) + for (t1=0;t1<=floord(M-1,32);t1++) + for (t2=0;t2<=floord(N-1,32);t2++) + for (t3=0;t3<=floord(K-1,32);t3++) + for (t4=32*t1;t4<=min(M-1,32*t1+31);t4++) + for (t5=32*t3;t5<=min(K-1,32*t3+31);t5++) { + lbv=32*t2; + ubv=min(N-1,32*t2+31); + #pragma ivdep + #pragma vector always + for (t6=lbv; t6<=ubv; t6++) + C[t4][t6]=beta*C[t4][t6]+alpha*A[t4][t5]*B[t5][t6];; + } +</pre> +<p>In this example the innermost loop is parallel without any dependencies. </p> +</div> +</body> +</html> |
