November 10, 2017 - POP free of charge services still help EU organisations improve performance of parallel software

The POP project is helping developers and users of computationally intensive programs to accelerate their execution and thus enable them address bigger problems in less time and at minimum cost.

POP experts do that by first providing an “Audit” service on the performance of the parallel application. This gives a deep insight on the actual behavior of the application and, if the performance profile is not optimal, a second step, called “Performance Plan” is proposed to identify the fundamental causes of inefficiencies and make suggestions on how to improve the programs to maximize the use of available resources. Finally, in some cases, we also propose “Proof-of-Concept” follow up services to demonstrate the actual performance gains on a critical module and help customers apply the proposed code modifications in the entire program.

We rely on performance analysis tools, fairly mature, developed by the partners over the years, (especially Extrae and Paraver from BSC and Scalasca from JSC) and focus on the methodological and best practice aspects of applying these tools. In addition, we have developed a unified set of metrics and analysis practices to maximize the insight provided to customers.

More than 100 assessments for real customers have already been performed. The customers belong to countries all over Europe. 25% of them are industrial SMEs and the rest academic. The customer satisfaction follow up we perform regularly confirm that a vast majority of customers are very happy with the service. See testimonies on our blog, and subscribe to our quarterly Newsletter

Recently, we set up a series of webinars to enlarge and reinforce our audience: three of them have already been carried out with success and a fourth one will be proposed in December. Further details can be found on the POP website, including recordings of our previous webinars.

If you’re not getting the performance you need from parallel software, please apply for help via the short Service Request Form, or email us to discuss further.
