Two major tasks: A) A library to generate generate graph compressed data structure (compressed sparse adjacency, edge matrix or list ): 1- to read in parallel (distributed parallelism —mpi or netCDF-4 parallel) raw data of simulation models which is available in netCDF. The size of data is of 10s to 100's of GBs. 2- To generate time series from read model data, which is in 3-dimensions: variable, time and location (gridded data). So from data you will have big number of time series. The has to be chunked in the different processors in a distributed memory architecture. 3- Two parallel functions: a) The calculation of the Pearson Correlation Coefficient between all time series to generate an edge or adjacency list out of it. Here, a user specified parameter will define a threshold between 0 and 1,and considering it, the function will build a corresponding edge list (and it should be compressed since the resulting correlation matrix after applying the threshold will be sparse, i.e lots of values less than the user specified threshold). The second is a function doing the same but by calculating the mutual information rather than pearson correlations. B) Suggesting a compatible parallel graph analysis package. If not, paralleling igraph package using openMP for multicore systems (and also for GPGPUS). This package has to read the produced data structure from (A), and will construct a graph from it, and will analyze (in parallel) the graph (weighted, directed, unweighted, etc), for example: degree, betweenness, community detection, etc.

Hi, we have read all the requirements and we are very confident to do this project from start till end. We definitely have some questions when we discuss project with you. Due to the change of bid system at freelancer.com, they ask freelancer to submit the project proposal at the time of bid. But it is not the right way, initially we can go through the requirements but we definitely need to spend time to write the proposal. Also they provide no place or private message unless you contact us, therefore we cannot submit the portfolio, examples site and our creative work. Also we do not post the portfolio and work examples publically to avoid other people copying it and claiming as their own. Please check our profile and the reviews given by the clients who have worked with us and see how much they appreciate our work by giving us their wonderful word in shape of feedback. Please send us a message so we can submit the links of our portfolio and then you can review and if you like we can start discussing project to help you to reach the final decision. We shall finish this project in timely manner and will finish it in time. We offer IT, Web design, web development and Smart phone application development. We also give life time guarantee to our work. Thanks

Hello & Greetings, This is a project that looks right up my alley. I am familiar with various graph algorithms and in-fact they were part of my Masters thesis on combinatorial optimization. I am an expert programmer well conversant in multiple languages. We can develop this tool in C++/Java or perhaps some other scripting language depending on the requirement. I have used many linear algebra and graph libraries. I also have CUDA programming experience. Over 10+ years of programming experience, currently working as a research fellow. I write robust, clean, efficient and modular code that is easy to maintain and extend. Please see reviews for quality of my work. We can discuss the specifications and end application in more detail at a convenient time. Thanks & Looking forward, JP

I am a Data Scientist with extensive experience in Python and Java development. Dealing with 10-100GB certainly sounds like an interesting problem, ripe for parallelization! I have experience with MapReduce, Hadoop, (Hive, HDFS), MPI, & GPU Programming (CUDA). After discussing the format of the data, and clarifying the project goals with you, I will be able to determine what will be the best approach to solve this problem. Furthermore, I will adjust my bid and time estimate to provide you with more accurate expectations. When you get a chance, I would like to discuss the project in more detail with you. Also, please let me know if you have any questions about my experience/capabilities. Regards, William

I have 7 years extensive experience with MATLAB in various simulation and data manipulation projects. I have previously built a multi-dimensional variable analysis tools (with MATLAB) for high frequency time series (stocks or physical) analysis. The tools does data segmentation, statistical clustering and correlation analysis.
