Long Qu - HPC Software Development Engineer

Long received his Ph.D. in Computer Science from the University of Paris-Sud in 2014 and is a computer scientist focusing on high performance computing (HPC).

Just before graduation, Long joined Total in 2013 as an HPC software engineer to design and develop software for processing geophysical data in the fields of seismic imaging and modeling the subsurface and seismic acquisitions in order to achieve the necessary performance for geosciences studies run on Total’s supercomputer.

Over the course of his studies and career, he has specialized in numerical algorithms, parallel computing software development and performance analysis and tuning using advanced computer architectures, programming methodology and tools for supercomputers.

C/S: Design and develop a fault tolerance job scheduling framework using client/server architecture for in-house seismic imaging applications run on Total’s supercomputer. The framework ensures very high availability of the supercomputer and makes it possible to monitor and adjust the resource used to produce seismic studies in real time. It allows seismic studies to continue operating properly in the event of software or hardware failure. The C/S also integrates a new feature known as an I/O server that aggregates I/O to reduce storage and network contention of the HPC system.

WPC: Redesign and implement dedicated software to compress seismic data. It is extremely fast, since it is particularly tuned for use in in-house seismic imaging workflow and is now required for production. This technology reduces contention of the network and storage components of the supercomputer and improves processing throughput for in-house seismic applications. WPC is a key enabler for selecting GPU technology for Total’s next generation of supercomputer. It has been selected as an Exploration & Production Best Innovators finalist in 2019.



Long is the author and co-author of several publications and communications in the fields of high-performance computing (Supercomputing, SEG and EAGE conferences) and the inventor or co-inventor in the following patent applications.

  • Method of input data compression, associated computer program product, computer system and extraction method.
  • Supercomputer system, method of data transmission in such supercomputer system and associated computer program product.
  • Method for data compression and associated decompression method, computer program product, seismic receiver and seismic data acquisition system.

Long is also a member of HiPEAC, a European network of computing systems researchers and industry representatives.
