Inspiration In high-throughput production environments, every sensor reading tells a story. Test systems continuously record Pressure, Temperature, and Differential Loss (DL) across thousands of cycles, but much of this data remains passive, observed but not interpreted. We set out to change that by deploying machine learning directly at the edge on a BeagleBone Black board. The goal was not anomaly detection, but live inference: to compute what the ideal DL should be (DL_pre

In the world of software development, the GNU Debugger (GDB) is an essential tool for programmers. It allows us to peer inside a running program, find bugs, and understand complex code. As new hardware architectures emerge, it's crucial that our tools keep pace. One such rising star is RISC-V, an open-source instruction set architecture that is rapidly gaining popularity, particularly with its new vector extensions for high-performance computing. The Challenge: An Unknown Ins

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 (Frontend Bound

The Leap into the Unknown Stepping out of the academic bubble and into the professional world is often painted as a daunting transition. For us, it was less a leap of faith and more an excited dive into the deep end, specifically, into the innovative waters of WhileOne.Our motivation to join was simple yet profound: we sought a place where curiosity was celebrated, challenges were seen as growth opportunities, and real-world impact was a daily pursuit. Little did we know that

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

Fuzzing RISC-V compilers like GCC and LLVM is a crucial practice for ensuring the correctness and security of the entire software ecosystem built on this architecture. It's not about finding vulnerabilities in the final compiled code, but rather about discovering bugs within the compiler itself that could lead to incorrect code generation, unexpected behavior, or even exploitable flaws. Why Compiler Fuzzing is a Unique Challenge Fuzzing compilers is different from fuzzing a

In the world of Site Reliability Engineering (SRE), trust, knowledge, and execution matter more than anything else. When our team was presented with the opportunity to support one of the leading clients in the inference systems domain, we knew the competition would be fierce. Many well-established and much larger organizations were bidding for the same project. Yet, we saw this as an opportunity to prove that expertise, dedication, and the right approach can outweigh size and

This blog post dives into a head-to-head performance comparison of two leading contenders: AWS Graviton4 (powering AWS r8g instances) and Google Axion (powering GCP Axion instances), both built on the advanced Arm Neoverse-V2 architecture. We'll examine their performance with Valkey 8.0.1, a popular in-memory data store. The Contenders: AWS Graviton4 and Google Axion AWS Graviton and Google Axion represent the latest generation of ARM-based server processors from Amazon and G

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. Performance Results Summary (100-second duration) Below is a consolidated view of our 100-second bd

Complex computing environments, spanning cloud, HPC, AI, and edge workloads; observability is no longer optional. With multiple layers of hardware and software working together, traditional monitoring alone cannot surface the insights needed for optimizing performance or preventing downtime. At Whileone Techsoft Pvt. Ltd., we help companies go beyond monitoring by building deep observability frameworks that connect performance benchmarking, system analytics, telemetry, and pr

Overview MySQL is an open-source relational database management system (RDBMS) that stores and organizes data using tables, rows, and columns, and allows you to query and manage that data using SQL (Structured Query Language). MySQL Database Server is fast, reliable, scalable, and easy to use. It continues to rank highly in popularity among databases, according to DB-engines. SysBench is a multi-threaded benchmark tool. The tool can create a simple database schema, populate d

Benchmarking SPECint on FPGA: Introduction With the growing interest in AI hardware for high-performance and power-efficient computing, understanding how industry-standard benchmarks perform on such platforms is critical. In this paper, we focus on SPECrate®2017 Integer workloads, a widely-used CPU benchmark suite, and share a case study comparing various runs on an FPGA target: a base run and a tuned run that achieved better performance. This paper describes how the tuning a

Benchmarks are vital for evaluating High-Performance Computing (HPC) system performance, guiding hardware choices, and optimizing software. This whitepaper focuses on understanding and overcoming bottlenecks in HPC benchmarks for CPU environments, specifically considering ARM/AARCH64 architectures, using miniFE and GROMACS as examples. 1. Introduction to miniFE and GROMACS Benchmarks 1.1. miniFE: A Finite Element Mini-Application miniFE, part of the Mantevo suite, simulates i

LLMs are Getting Better and Smaller Let’s look at Llama as an example. The rapid evolution of these models highlights a key trend in AI: prioritizing efficiency and performance. When Llama 2 70B launched in August 2023, it was considered a top-tier foundational model. However, its massive size demanded powerful hardware like the NVIDIA H100 accelerator. Less than nine months later, Meta introduced Llama 3 8B, shrinking the model by almost 9x. This enabled it to run on smaller

Building a great product is only half the battle. Demonstrating its capabilities convincingly — whether in front of customers, at an exhibition, or during a PoC — is often what seals the deal. Yet, for many companies, setting up demos ends up as a side project that falls through the cracks. At Whileone, we understand this challenge. That’s why helping companies build reliable, repeatable demos has been part of our mission since day one. The Problem with Ad-Hoc Demos Most comp

Meta’s Llama 4 Scout, released in April 2025, is a 17-billion parameter general-purpose language model that brings powerful reasoning to a broader range of applications—including those running without GPUs. This blog focuses on benchmarking Llama 4 Scout on CPU-only systems, covering: Tokens per second Latency per token Prompt handling efficiency Quantization techniques Architecture-specific optimization for x86, ARM, and RISC-V (RV64) Converting to GGUF format for efficient

JetStream is a JavaScript benchmark suite that evaluates web application performance by measuring the execution latency and throughput of complex workloads. With the release of JetStream 2.2, we at WhileOne Techsoft undertook the task of migrating its harness to a modern Node.js-based setup. Recently while working with a customer who was looking to benchmark their CPU using some js workloads. This post dives into why we did it, how we did it, and what you can expect from the.

SPEC CPU2017 is a well-known benchmark suite for evaluating CPU-intensive performance. Although it assumes native compilation and execution, there are cases—especially with RISC-V (RV64) platforms—where cross-compilation is the only feasible route. This guide walks through the steps to cross-compile SPEC CPU2017 for RISC-V, transfer the binaries to a target system, and optionally use the --fake option to simulate runs where execution isn't possible or needed during developmen
