Hello All, I am looking for an expert CUDA programmer to complete the following tasks in Windows. Please only apply if you very familiar. Please be prepared to do a coding challenge live. Here are the tasks needed: 1) Sort a 1-dimensional array of double / float 2) Sort an 2 dimensional with n-colum array of double / float by a single dimension (rowwise or columnwise) 3) Pearson correlation coefficient of two columns in an 2 dimensional N-column array 4) Spearman correlation coefficient of two columns in an 2 dimensional N-column array (this basically consists of sorting the arrays and calculating the Pearson coefficient on the indices) 5) Kendall correlation coefficients of two columns of an 2 dimensional N-column matrix 6) Covariance of two columns of a 2 dimensional N-column array 7) Covariance matrix for an 2 dimensional N-column array Final deliverable should be performant, memory efficient, and tunable to maximize utilization of a specific processor. coding should be neat and clean, with a reasonable amount of well-formatted comments. Feel free to use additional libraries like cuBLAS to perform the tasks.

Hello, I can see that you're looking for a developer who has experience in CUDA Programming along with the expertise in C++. It seems perfect match to my skills as I have worked as GPU Programmers for 2 years and have integrated CUDA with C++ and OpenCL. I am pretty much sure I can help you with sorting, Pearson & Spearman correlation and other points. Please initiate the chat so that can discuss in detail and come to conclusion. I look forward to discussing more. Warm regards, Ezaj A

Hi! I studied aerospace engineering and a master's in space systems. Now I am doing my PhD about stratospheric airships and doing a Math degree. I love maths and physics, and I have experience studying turbulent flows. I did two CUDA courses with Nvidia in 2016 as part of my PhD

The idea would be to use existing building blocks. Thust offers nearly best industrial performance for GPU sorting, CUB easily organizes batched processing. We should start by preparing the correctness test suite. Based on reference results for known inputs, I will rewrite gold implementations to maximize GPU utilization. Please note though that in order to fully load a modern GPU, e.g. Pascal P100, you would need extremely large correlation matrices (8K x 8K+) which is likely impractical. You might want to develop massive GPU batch-processing of average-sized correlations instead.
