measuring throughput between 2 c6678 DSP cards.



We ordinarily use the ubuntu 12.10 linux operating system to run the DSPC modules.  We have no idea how to write the code to conduct a bandwidth throughput test under the following case scenarios?

Test A (Single DSP pair writes):

DSP 0 on Card A writes to DSP 0 on Card B; throughput is measured

 

Test B (Single DSP pair reads):

DSP 0 on Card A reads  from DSP 0 on Card B; max throughput is measured

 

Test C (All DSP pairs bi-directional writes):

Each DSP on Card A writes to the corresponding DSP on Card B

Each DSP on Card B writes to the corresponding DSP on Card A

 

Test D (All DSP pairs bi-directional read):

Each DSP on Card A reads from the corresponding DSP on Card B

Each DSP on Card B reads from the corresponding DSP on Card A
