We recently worked on extending Intel Perfspect ( https://github.com/Whileone-Techsoft/PerfSpect/tree/Neoverse-native-support ) , a robust, command-line performance analysis tool that implements the Top-Down Microarchitecture Analysis Method (TMAM). It   fully supports the Arm Neoverse-V2  architectures. This project required mapping the Performance Monitoring Unit (PMU)  events on the ARM cores to the metrics of TMAM methodology. We can now get the Level 1  breakdown (Fronte

Performance analysis can often feel like searching for a needle in a haystack. When your application isn't running as fast as you'd like, where do you even begin to look? Is it a memory bottleneck? Are you stalling in the CPU's front-end? Answering these questions is critical, but traditional tools can be complex and overwhelming. This is where Intel's PerfSpect comes in. And now, thanks to some recent contributions, this powerful tool is no longer just for x86 systems. I'm h

We conducted SPDK bdevperf tests on an AWS EC2 r8gd.metal-24xl instance, focusing on single CPU core performance under high I/O load. Our objective was to demonstrate a CPU-bound workload. Results show low I/O wait and high CPU utilization, confirming the CPU is the limiting factor. The 2-disk configuration achieved the highest throughput, indicating a CPU saturation point. 1.

Automation is essential for  performance benchmarking  because it ensures that results are reliable, repeatable, scalable, and comparable. Various open source benchmarking tools are used for Automation.  Tools are essential for benchmarking because they bring standardization, accuracy, efficiency, and repeatability to performance evaluation. Open-Source Benchmarking Tools that support ad-hoc extensibility, meaning they can be customized or extended without rebuilding or heavi

1. Introduction High-Performance Computing (HPC) is at the core of solving complex computational problems in scientific research, engineering, and large-scale data analysis. Benchmarking plays a critical role in evaluating and optimizing HPC system performance. The Standard Performance Evaluation Corporation (SPEC) provides widely recognized benchmarking suites tailored for different computing environments, helping researchers, businesses, and hardware vendors assess system c

A debugging tool, GCeasy is used while generating reports of performance engineering.

At Whileone we take pride in customer's success. We help customers achieve goals and execute out of the box ideas that are necessary for success. One such project was to get IPCs for cloud applications on different architectures, completely omitting network stack. This would give the RISC-V chip designing customer a good picture whether architecture IPC ( Instructions per Cycle ) is inline with competition like Intel or ARM.  To achieve this, we modified cloud applications to
