Acceleration application areas

Acceleration applications exist in almost any endeavor that requires large-scale computationally

intensive problem solving. There are off-the-shelf applications available, although a significant

percentage of Acceleration applications are developed in-house by customers addressing very

specific needs. The following list indicates some of the typical acceleration applications areas.

 Scientific research

– Computational chemistry and biology

– Genetic research

 Engineering

– Engineering analysis

– Signal processing

– Seismic processing

– Video transcoding

 Business and financial

– Business Intelligence

– Database analytics

– Financial analysis

– Risk management

Support for visualization and acceleration products in

ProLiant servers

Visualization and Acceleration products place greater demands on system resources than most other

hardware add-ins. HP Engineering has invested extensive time and effort to ensure that the HP

ProLiant server platforms provide the best support possible for these products and for the applications

that use them.

Almost all high-end visualization and acceleration applications involve the manipulation of massive

data and results sets. Although most GPU-based accelerators use onboard memory to contain and

process data sets, most high-end applications require the movement of large data and result sets

between system memory and the accelerator board. Accomplishing this quickly and efficiently

requires a great deal of I/O bandwidth. In order to provide the best support for accelerator products,

HP has incorporated true x16 PCI Express slots into many of its ProLiant servers. On servers using the

new 5 Gb/s per-lane signaling rate of PCIe 2.0, these x16 slots are capable of providing 8 GB/s of

send and receive bandwidth, for a total bandwidth of up to 16 GB/s.

Additionally, many of the x16 slots incorporated into ProLiant servers support full length, full height

PCIe cards, which is a requirement for most accelerator cards. Many of the more powerful accelerator

cards occupy the space of two physical slots. Although these cards are not supported on the smaller

2U servers, they are supported on some of the larger servers.

As high-performance compute engines, accelerator cards can use significantly more power than most

other PCIe cards. This isn't surprising, considering that a typical graphic processor by itself can
