Corning Community College CSCS2650 Computer Organization ======PROJECT: Prime Number Computation (PNC1)====== =====OBJECTIVE===== Continue exploring algorithm/implementation comparison and optimization with respect to various approaches of computing prime numbers. =====TASK===== Add to your two separate, independent programs, one in Vircon32 C, and other in Vircon32 assembly, functionality that: * implements individual and combined functionality for the following optimizations (both in C and assembly): * odds: above 2, does odds-only processing (both number and factor check) * break: breaks from trial division/brute force when a viable factor is found (break on composite) * sqrt: only processes up through the square root point of the number being evaluated * possibilities here include the 3 identified variants (odds, break, sqrt) along with their combinations (odds+break, odds+sqrt, break+sqrt, odds+break+sqrt) * collects the same timing data with common workloads to the brute force variants from pnc0 * new variants added to the runtime graph you made in pnc0, adjusting and re-running pnc0 variants to allow for a consistent presentation of information * you may consider a lower upper-bound runtime threshold for the pnc1 variants (perhaps somewhere between 2 and 8 seconds, compared to the 16 seconds for pnc0). * be sure to use distinctive colors/patterns to distinguish items on the graph (again, line graph is a recommended choice) =====REFERENCE===== The following are reference screenshots of what your implementations should approximate. ====PNC1==== ===C implementation=== {{:haas:spring2024:comporg:projects:pnc1runtime.png|}} =====EDIT===== You will want to go [[/notes/comporg/spring2024/projects/pncX|here]] to edit and fill in the various sections of the document: * [[/notes/comporg/spring2024/projects/pncX|https://lab46.g7n.org/notes/comporg/spring2024/projects/pncX]] {{page>notes:comporg:spring2024:projects:pncX&nouser&nodate&nomdate&editbtn}} =====SUBMISSION===== To be successful in this project, the following criteria (or their equivalent) must be met: * Project must be submit on time, by the deadline. * Late submissions will lose 33% credit per day, with the submission window closing on the 3rd day following the deadline. * Executed programs must display in a manner similar to provided output * output formatted, where applicable, must match that of project requirements * Processing must be correct based on input given and output requested * Output, if applicable, must be correct based on values input * Code must be nicely and consistently indented * Code must be consistently written, to strive for readability from having a consistent style throughout * Code must be commented * Any "to be implemented" comments **MUST** be removed * these "to be implemented" comments, if still present at evaluation time, will result in points being deducted. * Sufficient comments explaining the point of provided logic **MUST** be present * No global variables (without instructor approval), no goto statements, no calling of main()! * Track/version the source code in your lab46 semester repository * Submit a copy of your source code to me using the **submit** tool by the deadline. ====Submit Tool Usage==== Let's say you have completed work on the project, and are ready to submit, you would do the following: lab46:~/src/SEMESTER/DESIG/PROJECT$ submit DESIG PROJECT file1 file2 file3 ... fileN You should get some sort of confirmation indicating successful submission if all went according to plan. If not, check for typos and or locational mismatches. =====RUBRIC===== I'll be evaluating the project based on the following criteria: 286:pnc1:final tally of results (286/286) *:pnc1:submitted C and assembly implementations [26/26] *:pnc1:each implementation builds cleanly [26/26] *:pnc1:output conforms to specifications [26/26] *:pnc1:processing is correct, and to specifications [26/26] *:pnc1:working break on composite optimization [26/26] *:pnc1:working odds only processing optimization [26/26] *:pnc1:working sqrt factor cap optimization [26/26] *:pnc1:all variants and combinations thereof operational [26/26] *:pnc1:graph produced from timing data produced [26/26] *:pnc1:graph posted to discord and documentation page [26/26] *:pnc1:timing data is taken out to 3 decimal places [26/26] ===Pertaining to the collaborative authoring of project documentation=== * each class member is to participate in the contribution of relevant information and formatting of the documentation * minimal member contributions consist of: * near the class average edits (a value of at least four productive edits) * near the average class content change average (a value of at least 1024 bytes (absolute value of data content change)) * no zero-sum commits (adding in one commit then later removing in its entirety for the sake of satisfying edit requirements) * adding and formatting data in an organized fashion, aiming to create an informative and readable document that anyone in the class can reference * content contributions will be factored into a documentation coefficient, a value multiplied against your actual project submission to influence the end result: * no contributions, co-efficient is 0.50 * less than minimum contributions is 0.75 * met minimum contribution threshold is 1.00 ===Additionally=== * Solutions not abiding by spirit of project will be subject to a 50% overall deduction * Solutions not utilizing descriptive why and how comments will be subject to a 25% overall deduction * Solutions not utilizing indentation to promote scope and clarity or otherwise maintaining consistency in code style and presentation will be subject to a 25% overall deduction * Solutions not organized and easy to read (assume a terminal at least 90 characters wide, 40 characters tall) are subject to a 25% overall deduction
