Dear SIGMOD 2009 author, In case you volunteer to participate in the Repeatability & Workability Evaluation process for accepted SIGMOD 2009 papers, we kindly ask you to prepare the following and make it available for us to download, preferably by Wednesday April 22 2009. - Camera-ready version of your accepted SIGMOD 2009 paper (as PDF). - Your code plus scripts and instruction to compile it on (at least) the same platform (hardware architecture and operating system) as you used (see details below). In addition to the code, you can also provide pre-compiled binaries. In the exceptional case that your cannot provide us (RWE + RWC) with your code for good reasons (i.e., strict commercial IP limitation --- please explain in detail!), supplying only your binaries would be acceptable. - Scripts/programs to run your experiments, extract the data as used in your papers and present the results as tables, graphs, etc. as in your paper. Please make sure, you document your scripts/programs well and include detailed usage instructions. Describe each experiment individually and relate it to the respective section and/or table/figure in your paper. For the "workability" evaluation, please also provide scripts/programs for alternative and/or additional experiments that go beyond the ones presented in your paper, or at least include suggestions how to modify and/or extend your experiments by using alternative datasets and/or different parameters. - The datasets (and/or data generators) you used for your experiments plus preferably alternative/extended/modified datasets for extended experimentation for the "workability" evaluation. Pointers to the original sources of publicly available datasets (and/or generators) are also acceptable. - Specifications of the computer system(s) required to run your experiments, including the following information: + Operating System (e.g., "Windows Vista 32bit", "Fedora 9 (Linux 2.6.25)", "MacOSX 10.5 Leopard (Darwin 9.5.0)", etc.) + Class of hardware (e.g., Laptop, Desktop, Workstation, Server, ...) + CPU type (e.g., "Intel Core2 Quad CPU Q6600 @ 2.40GHz", "Intel Pentium M (Dothan) @ 1.50GHz", etc.) + # cores per CPU + # CPUs per machine + main memory (RAM) size per machine + storage/disk system (e.g. "single 120 GB laptop disk @ 5400 RPM", "5x 500 GB S-ATA disk at 7200 RPM as RAID-0", "32 GB SSD", etc.) + free disk space per machine - Information about required software, like DBMSs, compilers, scripting languages, virtual machines, compilers, tools, etc. The following DTD and XML example should help you to collect and organize this information in a "standardized" format: SIGMOD-2009-RWE.dtd SIGMOD-2009-RWE.xml Preferably, create a clear directory structure to collect the above listed collections of files, and pack everything into a portable archive (e.g., zip, tar). In case you have any comments and/or questions regarding the SIGMOD 2009 Repeatability & Workability Evaluation process, please do not hesitate to contact us. We will provide you with further details about Wiki/Blog for interaction with the reviewers within the next two weeks. Thank you very much in advance for your cooperation.
