Ybsis Inc. has been involved in high performance computing for 15 years.

Performance analysis

Pinpointing performance bottlenecks is the first step in in HPC, following the Pareto rule, often 80% of the performance issues are caused by 20% of the code. Using commercial or open source tools or writing custom analyzers permits us to precisely narrow down on the culprit code.

Tools	Use
Quantify (IBM)	profiling of application
Purify (IBM)	Memory analysis, memory leaks	Valgrind (OpenSource)	profiling and memory profiling

Parallelization

One of the key stone of high performance computing is the ability of redesigning existing algorithms to leverage parallel aspect in the data of in the tasks being processed.

Shared Memory , Multi-core

Distributed Systems

Understand and Translate Complex Requirements

Ybsis Inc. has a long experience translating domain specific business logic and problematic into implementable requirements. We follow an iterative approach, where early prototyping palys a central role in allowing us to gather end-user feedback. We have successfully delivered project in several industries:

CAD (semiconductor – EDA)
BioTech (Genetic, LIMS)
Internet (Search Engines, Ecomerce, Social networking)
Security (Public Key Infrastructure)

Early Prototyping

By leveraging dynamic languages like Ruby and Groovy, we are able to deploy prototypes and start focusing on delivering customer value early on. We typically rely on the following languages:

Language	Best When
Ruby	Integration with existing C/C++ code base, no Java
Grrovy	Existing Java expertise and code base
