Context And Mission

Within the Barcelona Supercomputing Center the Earth Sciences Department, led by Prof Francisco Doblas-Reyes, aims to deliver novel, advanced, and well-evaluated high-resolution global climate models capable of simulating and predicting climate estimations with unprecedented reliability.

The successful candidate will be part of the Performance Team, a sub-group in the section of Computational Earth Sciences.

This team, composed of 10 members but steadily growing, performs R&D tasks in the field of Earth System Modelling (ESM) performance : its goal is to identify model bottlenecks and research how to remove them.

The team has at its disposal cutting-edge performance tools, able to evaluate and represent different performance metrics.

Having identified those areas in the code, the experts in the team proceed to modify them without impacting the final results.

Possible solutions can go from using more efficient numerical algorithms to modifying the way the model exploits the HPC infrastructure.

Key Duties

  • The successful candidate will work on analyzing and tuning the I / O server computational performance of different Earth Science applications running at a very high-resolution configuration, as well as exploring and applying lossy compression techniques to the output data.
  • The candidate will also be involved in the development of the department's "common" applications : these include several applications whose interest is shared among different sub-group in the Earth Sciences department and whose number of users can range from small groups to several institutions.

    This position involves close interaction with the Climate Prediction group and external collaborators / software vendors.

  • Education
  • Having a Bachelor in Computer Science, Engineering, Mathematics, Physics or related discipline
  • Having a Master’s degree will be valued
  • Essential Knowledge and Professional Experience
  • Excellent computing skills in high-level computer languages (especially FORTRAN or C / C++) and experience with UNIX / LINUX environments and scripting languages (bash, Python,etc)
  • Programming skills to manage big and collaborative projects and experience with git
  • Knowledge of Input / Output approaches and tools as IO servers
  • Experience or knowledge in running and optimizing scientific codes on large HPC systems.
  • Experience or knowledge in HPC architecture and parallel programming (MPI and / or OpenMP) will be valued
  • Experience or knowledge in Data compression will be valued.
  • Experience or knowledge in the usage and support of Unix- or Linux-based HPC systems
  • Competences
  • Earth system models are sophisticated applications and High Performance problem-solving skills and a proactive attitude to address new challenges and perfect the current solutions so they gain in reliability and efficiency.
  • Computers are complex systems. The candidate needs to have excellent
  • This is a specialized position so the successful candidate is expected to have a demonstrated learning capacity and the motivation to maintain a learning progression during the contract.
  • The BSC Earth Sciences department is an international and interdisciplinary environment, so the candidate must be fluent in English and have good written and verbal skills and the capacity to support Earth and Computational scientists
  • Climate models are collaborative projects, so it is mandatory to be able to fulfill schedules and coordinate with members from other institutions, as well as to disseminate the advances in international workshops.
  • Conditions

  • The position will be located at BSC within the Earth Sciences Department
  • We offer a full-time contract, a good working environment, a highly stimulating environment with state-of-the-art infrastructure, flexible working hours, extensive training plan, tickets restaurant, private health insurance, fully support to the relocation procedures
  • Duration : Temporary - 2 years renewable
  • Salary : we offer a competitive salary commensurate with the qualifications and experience of the candidate and according to the cost of living in Barcelona
  • Starting date : June
  • Applications procedure and process

    All applications must be made through BSC website and contain :

  • A full CV in English including contact details
  • A Cover Letter with a statement of interest in English, including two contacts for further references - Applications without this document will not be considered
  • In accordance with the OTM-R principles, a gender-balanced recruitment panel is formed for every vacancy at the beginning of the process.

    After reviewing the content of the applications, the panel will start the interviews, with at least one technical and one administrative interview.

    A profile questionnaire as well as a technical exercise may be required during the process.

    The panel will make a final decision and all candidates who had contacts with them will receive a feedback with details on the acceptance or rejection of their profile.
