Your role and responsibilities
The Linux on IBM Z and LinuxONE Systems Performance team is looking for a Graduate to join and strengthen the team. We are responsible for designing, implementing, conducting, and analyzing stress workloads/benchmarks on IBM Z and LinuxONE to ensure customer expectations are met from a performance perspective.
As a Systems Performance analyst you are responsible for designing benchmark scenarios, implementing and tuning the workloads, conducting the workload measurements along with analyzing the performance data to guide Hardware, Operating System, and Software development teams on performance improvements.
You will learn about the different aspects of workloads and how to choose the right benchmark for individual scenarios. By investigating identified bottlenecks in the environment, you will understand the Linux operating system tuning capabilities, and adjust and fine tune the system to the required level of performance. By selecting different I/O connectivity and technology, you will learn how to right size the environment to get the optimal price vs performance balance. By analyzing IBM Z low level traces, which are captured during the measurements, you will gain deep insights into the IBM Z architecture.
This role is collaborative within a global team of IBM.
