| === Running the Sample Program using the Fabric ===
| |
| Section 10.5 of PDK Reference Manual explains how to run the sample software application. It has been reproduced below in brief.
| |
| | |
| The rev version installed on the Convey machine is from 2010-8-9; to copy the sample app's source code run:
| |
| cd ~
| |
| mkdir pdk_sample
| |
| cp -r /opt/convey/pdk/2010_08_09/cae_pers_vadd pdk_sample
| |
| cp -r /opt/convey/pdk/2010_08_09/pdk_apps/SampleAppVadd pdk_sample
| |
| | |
| To make the sample project.
| |
| | |
| cd ~/pdk_sample/cae_pers_vadd/CaeSimPers/
| |
| make
| |
| cd ~/pdk_sample/SampleAppVadd/
| |
| make
| |
| | |
| This compiles both an emulator (CaeSimPers) and a C program that makes a coprocessor call to use the vector adder (UserApp.exe). You'll want to make sure that you haven't set your environmental variables. You can do this by simply using a new terminal window or by running '''export CNY_SIM_THREAD='''. To run the sample application on the coprocessor fabric, you'll need to make sure the CNY_SIM_THREAD environment variable is unset or 0. To run the software version of the app:
| |
| | |
| cd ~/pdk_sample/SampleAppVadd/
| |
| ./UserApp.exe
| |
| | |
| You should see the program run and output the following:
| |
| | |
| [[Image:Assignment1.software.PNG]]
| |
| | |
| You can also set the CNY_CALL_STATS environment variable; this variable gives back the number of times the coprocessor was called. I.E. for this application, the coprocessor is called once. Output from the terminal is reproduced in the following file:
| |
| | |
| [[Media:Assignment1 team2 fabric.txt|Console Output]]
| |
| | |
| === Running in the SW Model ===
| |
| To run the sample application on the Coprocessor simulator, you'll need to set some environmental variables:
| |
| | |
| # Use the Coprocessor Simulator
| |
| export CNY_SIM_THREAD=libcpSimLib2.so
| |
| # Point to the emulator
| |
| export CNY_CAE_EMULATOR=~/pdk_sample/cae_pers_vadd/CaeSimPers/CaeSimPers
| |
| | |
| After setting the environmental variables, rerun the app:
| |
| | |
| cd ~/pdk_sample/SampleAppVadd/
| |
| ./UserApp.exe
| |
| | |
| The program will pause at the following screen for a 10-20 seconds...

| | |
| ...and then finish running the program.
