Assignment

Dealing with this high degree of storage heterogeneity is a real challenge for scientific workflows and applications. This PhD thesis proposes to model and simulate heterogeneous storage systems in order to study their behavior, predict their performance and propose innovative algorithmic approaches for better resource utilization.

Main activities

One of the aims of this thesis is to make better use of storage resources for scientific applications and workflows that are destined to run on exascale supercomputers. Initially, storage systems such as Lustre and DAOS will be studied, modeled and simulated in an existing WRENCH-based simulator, called StorAlloc, developed in the team. This study will shed light on the criteria influencing the performance of these systems. Secondly, advanced resource allocation algorithms will be proposed, implemented and evaluated in the simulator to overcome the limitations of existing methods.

Skills

• An excellent Master degree in computer science or equivalent
• Completion of a teaching unit in high-performance computing or distributed computing is an advantage
• Programming skills in C/C++ and Python
• Good communication skills in oral and written English.
• Open-mindedness, strong integration skills and team spirit

Benefits package

• Subsidized meals
• Partial reimbursement of public transport costs
• Possibility of teleworking (90 days per year) and flexible organization of working hours
• Partial payment of insurance costs

Remuneration

monthly gross salary amounting to 2051 euros for the first and second years and 2158 euros for the third year
