Hi, Based on the project description, i am guessing that the existing code is not implemented as multi - threaded application. we can reduce the execution time if we can implement it as a multi threaded program. we can create multiple pthreads in Linux to handle different tasks. As i have considerable amount of experience in designing and developing C/C++ applications i Can redesign existing code and will be able to identify the places where we can improve the code to reduce the execution time and memory utilization. I will assure you that the assigned tasks will be delivered with in time and with in Budget. As i am newcomer to Freelancer delivering it on time and on budget is more important for me as it will enable me to fetch more projects. looking forward to work with you. Thanks.

Hello. I am an experienced software developer with more than 20 years of C/C++ programming experience for Windows and Linux platforms. Also I've had rather extensive experience writing computational programs in FORTRAN. I've got experience in writing software supporting stock trading that demanded very fast decision making time so I know what fast code means. I have an university degree in computer science and rather solid background in applied mathematics and system modeling. I don't know exact direction of your scientific work but I hope that I can be helpful with your project. Ready to answer your additional questions if any. Kind regargs Iurii

Your description is short but it's not problem. I will use GDB debugger on Linux to back-trace flow that need to be optimized (time executing in your code), I will optimize some un-used code in your project. Example: - Replaced index++ by ++index to increase the For loop - Optimize data type to store data, I can use technical shift bit to do it. - Use pointers to access memory or inline or macros to increase performance. I hope I can make you happy!
