[Xenomai] Xenomai application tracing

[Xenomai] Xenomai application tracing

[ILESH PATEL]

Hi,

I used iperf network testing utility on my network.
My PC is configured with ubuntu 12.04 with Xenomai 2.6.2.1

So, I want to know iperf utility is running with real time environment path
or non real time environment path.

Please Give me hits tracing application.
So, I can know this application response is real time or non real time.

Thanks & Regard,
-Ilesh

It is a bit hard to know what you are testing, I mean you compiled 
iperf, we have no idea how you compiled it. So, to be safe, we will say, 
no, probably not, iperf is not using xenomai services.

Hi,

We are making bench mark of throughput,latency and Bandwidth of network
with Xenomai.
We make network of two i5-PC. On which Intel's 10G X-540-T2 NIC card is
installed on PCIe slot.
For measuring bench mark we use iperf ,netperf and jperf.

So I have little-bit of confusion about
1.   whatever I test  and measure using iperf and jperf is through real
time Xenomai or not ?
2.   Can we say  this bench-marking is real time bench marking with Xenomai
?


If above is not real time then
1.    Can you suggest some way to measure throughput, latency and bandwidth
of network using 10G NIC as real time using Xenomai.
2.    Or any way to use iperf with Xenomai as real time execution for
measure throughput, latency and bandwidth of network using 10G NIC ?


On our PC following packages is installed.
Ubuntu 12.04 with kernel 3.5.1
Xenomai 2.6.2.1
NIC driver ixgbe 3.15.1
iperf 2.0.5


We have installed iperf as the regular installation method.
I use the following command to install iperf

#./configure
#make
#make install

Hi,

so no, iperf is not compiled for Xenomai. In order to do real-time
networking with Xenomai, you need:
- a network driver for Xenomai, likely using RTnet
- an application compiled to use Xenomai services, if you want to port
an application using the POSIX API, which is probably the case of iperf,
you may have a look at this guide:
https://www.xenomai.org/index.php/Porting_POSIX_applications_to_Xenomai

Regards.
