ClearSpeed Technology plc

AdvanceTM e720 Accelerator Card User Guide Before you start

1.1 Hardware prerequisites

To install the Advance e720 accelerator board, you will need;

z an HP BladeSystem c-Class server or equivalent comprising of a 64-bit Intel or AMD

x86 processor (or compatible).

z An available Type II mezzanine connection. See manufacturers instructions; [1] on

page 11.

1.2 How to get the driver software

Before you can use the Advance e720 accelerator board, you must install the runtime
package and the driver software. The latest versions of the software and software
installation instructions can be found on the ClearSpeed support website:

http://support.clearspeed.com/

This website also provides the latest list of supported operating systems.

1.3 Card installation

The ClearSpeed Advance e720 Accelerator card is a Type II Mezzanine card. The type
determines where it can be installed in the server blade. Refer to your manufacturer's
detailed installation instructions to identify and install the Advance e720 Type II card (refer
to

[1] on page 11).

Caution: It is very important when inserting the card to observe the following

z Always follow the precautions for handling electrostatic sensitive devices by using the

antistatic wrist strap provided.

z Always follow the instructions provided by your system manufacturer when installing

new hardware.

z Do not use excessive force when inserting the Advance e720 accelerator board into

the mezzanine connector as this can damage the motherboard.

Features and general description AdvanceTM e720 Accelerator Card User Guide

2 Features and general description

The Advance e720 accelerator card (shown in Figure 2) is based on the CSX700
double-precision, floating-point accelerator. It is designed for use in HP blade servers and
systems that provide Type II mezzanine compatible connectors.

Figure 2. Advance CSX700 mezzanine card.

The Advance e720 accelerator card uses a single CSX700 processor. The processor
implements the PCI Express host interface, permitting high data transfer rates directly with
the processor. To manage the e720, an FPGA device is used. The firmware represents the
FPGA design image and can be upgraded, as described in the [5], Firmware Update
Release Notes.

The Advance e720 accelerator card uses dual channel bus-mastering DMA to achieve a
high peak bandwidth to the host system. Each card has 2 GBytes of local card memory with
error correction. It includes onboard temperature monitoring of the processor and board.

The Advance e720 accelerator card features the CSX700 data-parallel floating-point
coprocessor. The processor is energy efficient providing 3.84 GFLOPS per watt
(96 GFLOPS/25 watts). Each processor consists of two computation arrays, each are fully
interconnected through a common address map, including access to the 1 GByte of local
DDR2 SDRAM attached to each array, giving a total of 2 GBytes for the card. The DRAM is
72 bits wide, including 8 bits of error correcting code (ECC). This allows correction of
single-bit errors and detection of multiple-bit errors.

ClearSpeed Technology plc

AdvanceTM e720 Accelerator Card User Guide Features and general description

2.1 Firmware

Board level management is implemented in an FPGA. At power-on, the FPGA logic
configuration is loaded from a flash memory device. The contents of the flash device can be
re-programmed to upgrade functionality or performance using a software utility supplied by
ClearSpeed. This utility runs on the host system and reprograms the flash device through
the Advance e720 accelerator card’s register space.

For more detailed information, see [4]: Firmware Installation Guide.

Troubleshooting - general guidelines AdvanceTM e720 Accelerator Card User Guide

3 Troubleshooting - general guidelines

If you encounter an error when using the Advance e720 accelerator board, you need to
isolate the cause of the problem.

When installing multiple cards and software in a system, install each in turn and restart the
system each time. Similarly, if you have already installed the Advance e720 accelerator
board and software and you experience problems, remove or uninstall each in turn to
establish which one is causing the problem.

3.1 Solving the problem

3.1.1 Finding the cause of the problem

To find out what is causing the problem, we recommend that you check the following:

z Check your Advance e720 accelerator board is installed correctly. See the relevent HP

Blade Server User Guide

z Check you installed the drivers correctly.

Whenever you fix a problem and reboot, run the tests again.

3.1.2 Contacting ClearSpeed Support

If none of the above helps solve your problem, refer to the ClearSpeed solutions
knowledgebase or you can report your problem by submitting an online report via the
ClearSpeed support website at:

http://support.clearspeed.com/support/solutions/

1. You may use the Hewlett Packard BladeSystem c-Class Onboard Administrator software, or the BladeServer’s
Lights Out remote management feature, to confirm installation of the ClearSpeed e720 Mezzanine Card. Refer
to the HP Onboard Administrator or HP iLO2 documentation for full details.

4.4 Thermal

To keep the CSX700 cool, the Advance e720 accelerator card is fitted with a passive
heatsink. The passive heatsink is
convection. For the passive heatsinks to work, they require airflow moving across the fins.

To ensure that the Advance e720 accelerator board is operating within the published limits,
the BladeSystem’s ambient operating temperature should be as specified in

4.4.1 Temperature monitoring

The CSX700 and the FPGA contain on-die temperature-sensing diodes which are
connected to temperature-monitoring devices. Each device measures the remote
temperature (temperature of the measured die) and the local temperature (temperature of
the monitor chip itself). The temperature monitors signal warnings if the temperatures rise
above the thresholds shown in

Table 4. Temperature warning thresholds

There are two warnings:

z Temperature alert. This provides an indication to the driver software that the device is

becoming hot.

z Critical temperature. This turns off the device before it gets hot enough to cause

permanent damage.

4.4.2 Temperature shutdown

When the CSX700 reaches a critical temperature it is immediately held in reset so that it can
cool and avoid being damaged. When the CSX700 has cooled by more than 25
critical threshold, it is brought out of reset.

Following a critical temperature reset your blade server may require a reboot to reconnect to
the ClearSpeed e720.
