TANGO Development-time tooling: Leveraging a Framework from Operations Research for optimal software placement and task scheduling on heterogeneous hardware platforms

In the emerging era of Internet of Things and Big Data processing, the paradigm of software development is shifting. In particular, many IoT and Big Data problems can be solved using vector and matrix operations and these operations can be drastically accelerated by using massively parallel processing units such as GPU and FPGA, which are now integrated in many recent heterogeneous platforms found on the market.

Energy considerations with the TANGO Programming Model and Runtime

One of the recent trending topics in computer science research is the reduction of energy and power consumed by computers. Part of this research is focused on providing low power architectures and accelerators which can achieve good performance at low power. However, an application should be modified to take advantage of this heterogeneous architecture.

Characterizing your application power profile using TANGO Device Supervisor

Submitted by admin on

TANGO project aims to deliver the best way to run application with low power consumption. TANGO helps defining the right hardware (CPU, GPU, FPGA …) according to the application needs. The Device Supervisor (defined in the global TANGO architecture) is in charge of managing the available resources from their allocation to their usage. One of the key parameter to follow is the energy consumption.

TANGO for the Embedded World

Submitted by admin on

Two decades ago, parallel programming was a technology restricted to large scale specialised applications that were running in computing centres. Today’s picture is very different with the generalisation of multi-core processing devices, not only inside desktop computers, but inside embedded and mobile devices as well.

Image processing, The Internet of Things (IoT) and cloud computing are examples of domains in which concurrent cooperative programming, that-is-to-say parallel programming, develops widely.

TANGO Development-time tooling: Guiding software design decision for exploiting heterogeneous hardware platforms’ capabilities

Jean-Christophe Deprez's picture Submitted by Jean-Christophe... on

Designing and developing software with an efficient execution on distributed environment with fairly standard homogeneous processing nodes is already a difficult exercise. This complexity explodes when targeting a heterogeneous environment composed not only of distributed multi-core CPU nodes but also including accelerators with many-core CPUs, GPUs and FPGAs.

Quality of Monitoring Data with IPMI and RAPL

One of the main objectives of the TANGO Project is to be able to optimize energy usage of applications in a HPC environment, including the prospect of handling heterogeneity such as CPUs, GPUs and FPGAs.

A key start to optimisation is the ability to monitor such infrastructures and to ensure the data obtained is accurate and consistent. The accuracy of this data is particularly useful when constructing power models that can be used to estimate future power consumption based upon expected utilisation. In this blog we provide key recommendations and findings from performing calibration on our infrastructure.

Building applications for heterogeneous hardware

David Garcia's picture Submitted by David Garcia on

When designing the architecture of the TANGO project we saw the necessity of a central component that helps to speed up the building process for different targeted heterogeneous architectures with different optimizations and deploy them if the different testbeds, especially in HPC use case, this ended up in the creation of Application Lifecycle Deployment Engine or ALDE. Let’s check step by step how will be shaped and which functionality and steps it is going to perform.

Our team has been working hard during the last months to release the first version of the Toolbox and establishing an initiative to strengthen the market using heterogeneous hardware and software. The most relevant things during these last months are:

Monitoring heterogeneous architectures

David Garcia's picture Submitted by David Garcia on

One of the main objectives of the TANGO Project is to be able to optimize energy usage of applications in an heterogeneous environment –where by heterogeneous we are understating a mixture of different processor devices, such as CPUs, GPUs, FPGAs, DSPs, and so on.- One of the main challenges is to be able to monitor energy usage of those devices without the necessity of intrusive measurements, such as adding over the top physical probes.
