Run MPSoCBench

[erwan....@gmail.com]

Hi MPSoCBench Developpers,

I have a problem with the command : git submodule update --init --recursive.
When I launch   sh setup.sh ../ArchC-2.4.0/ when I am following your tutorial I get this output :
-ne --------------------------------------------------------------------------------------------
-ne SETUP: Initiating the submodules...
-ne SETUP: Copying the Environment file from ArchC to MPSoCBench...
-ne SETUP: SUCCESSFUL!
-ne --------------------------------------------------------------------------------------------
-ne The new file called 'env.sh' will set the environment variables to MPSoCBench work properly.
-ne So, whenever you are in a new terminal (bash), run:
-ne     source env.sh
-ne Or put the following command in your ~/.bashrc:
-ne      source /home/erwan/Documents/Logiciels/MPSoCBench/MPSoCBench-2.0.0/env.sh

At the beginning I had a "fatal" with the git command because I haven't git so I installed it and I did the command "git init" at the directory /home/erwan/Documents/Logiciels/MPSoCBench/MPSoCBench-2.0.0
And after I get the successful "sh setup.sh ../ArchC-2.4.0/" above

After that I use the command source env.sh (there is no errrors)

Finally, I enter the command ./MPSoCBench -h and it tells me to do :  git submodule update --init --recursive

May you tell me what is the problem?

Thank you in advance, best regards.
Erwan

In order to find a solution I downloaded a clone with  git clone https://github.com/ArchC/MPSoCBench.git
It worked fine and after that I launch ./setup.sh ../ArchC-2.4.0/
and I get this error :
--------------------------------------------------------------------------------------------
SETUP: Initiating the submodules...
Clonage dans 'processors/arm'...
Warning: Permanently added the RSA host key for IP address '192.30.252.129' to the list of known hosts.

and the repository exists.

SETUP: Copying the Environment file from ArchC to MPSoCBench...

SETUP: SUCCESSFUL!
--------------------------------------------------------------------------------------------

The new file called 'env.sh' will set the environment variables to MPSoCBench work properly.

So, whenever you are in a new terminal (bash), run:

    source env.sh

Or put the following command in your ~/.bashrc:

     source /home/erwan/Documents/Logiciels/MPSoCBench/MPSoCBench/env.sh

I'm sorry but I don't know how to fix that problem, may you help me please?

Thank you in advance,
Erwan

Hello Erwan,

I hope you are pretty well!

After reading your second e-mail, it seems that the submodules (the processor modules) were properly stored in your MPSoCBench. 

The env.sh script handles the environment variables in order to run the ArchC and other tools. 

Please run the following commands and send to us the output messages, and we will help you to solve the problem.

$ cd MPSoCBench

$ source env.sh 

$ ./MPSoCBench -h 

Best regards,

Liana.

Hello Erwan,

The first problem happened because you did not have the "Git" installed. I think that you solved this problem after installing it. 

But, anyway, I think you also did not have permission to clone them. 

So, the ArchC support updated the way to clone the git submodules, in order to allow that any user clone them. 

I recommend that you start the process again:

- delete all MPSoCBench infrastructure

$ rm -rf MPSoCBench

- download the MPSoCBench 2.0 from  http://www.archc.org/benchs/mpsocbench/downloads.html  or https://github.com/ArchC/MPSoCBench/releases 

- unzip it

- run the script:    

$ sh setup.sh

(we hope that the submodules will be cloned now )

- run the environment script to configure your environment

$ source env.sh

- run the MPSoCBench , for example:

$ ./MPSoCBench -p=mips -i=router.lt -n=2 -s=dijkstra -b

Please let me know if you still have problems.

Liana.

<li>Download the <a target="_BLANK" href="https://github.com/ArchC/MPSoCBench/releases"> MPSoCBench 2.0</a></li>

<li>Unzip in the opt/ directory:</li>

<pre><span class="inner-pre" style="font-size: 16px">$ tar xvf mpsocbench.tar.gz </span></pre>

<li>Use the setup.sh script to download automatically the newest version of the ArchC processor models </li>

      <pre><span class="inner-pre" style="font-size: 16px">$ sh setup.sh </span></pre>

      <li>Use the env.sh script to configure your system environment automatically </li>

      <pre><span class="inner-pre" style="font-size: 16px">$ source env.sh </span></pre>

      <pre><span class="inner-pre" style="font-size: 16px">$ bash -l </span></pre>

Hello Liana,

I followed your instructions, retry the process. I deleted MPSoCBench files and directories and downloaded to http://www.archc.org/benchs/mpsocbench/downloads.html  

This what I get :

erwan@lo-lester-040:~/Documents/Logiciels/MPSoCBench/MPSoCBench-2.0.0$ sh setup.sh /home/erwan/Documents/Logiciels/MPSoCBench/ArchC-2.4.0

-ne The new file called 'env.sh' will set the environment variables to MPSoCBench work properly.

    git submodule update --init --recursive

erwan@lo-lester-040:~/Documents/Logiciels/MPSoCBench/MPSoCBench-2.0.0$

So, I deleted again the MPSoCBench folder and I did the command :  git clone https://github.com/ArchC/MPSoCBench.git

And this time setup.sh worked! :)

There is a progress but it's not totally solved.

I guess MPSoCBench do not find compilers that are in

Hello Erwan,

Yes, It was a progress! 

To solve this issue in my system, I used the following commands in the ~/.profile file:

export PATH=/opt/tools/compilers/mips-newlib-elf/bin:$PATH

export PATH=/opt/tools/compilers/arm-newlib-eabi/bin:$PATH

export PATH=/opt/tools/compilers/powerpc-newlib-elf/bin:$PATH

export PATH=/opt/tools/compilers/sparc-newlib-elf/bin:$PATH

(/opt/tools/compilers/ is the folder where I put these compilers)

Please try to use the command below in your MPSoCBench folder:

$ bash -l 

(the argument is a tiny L  :-) )

and try to run the command again:

 ./MPSoCBench -p=mips -i=router.lt -n=2 -s=dijkstra -b

While you try to follow these directions, I will verify if there are other causes for this problem. 

We keep talking.

Liana

[Rodolfo Azevedo]

 parte?Oi Liana,

  o env.sh já devia setar os caminhos dos compiladores. Ele está lá para isto.

  Quanto ao git, parece que você não testou baixar o pacote geral. Pelo visto, git submodules só funciona se o principal for baixado do git também. Pode checar esta parte?

[Felippi Crominski]

For solve that problem with git submodules I use:

On folder of MPSocBench,

rm processors -r

git init

git submodule add https://github.com/ArchC/mips.git processors/mips

git submodule add https://github.com/ArchC/sparc.git processors/sparc

git submodule add https://github.com/ArchC/powerpc.git processors/powerpc

git submodule add https://github.com/ArchC/arm.git processors/arm

I don't know if that solution is the best, but work for me.

[Liana Duenha]

Hi Rodolfo,

The env.sh is not prepared for set the compilers path yet (it starts path only for the ArchC, SystemC and MPSoCBench). So, in the currently version we need to edit the .profile once or the PATH variable. We will improve this issue  enabling cloning the compilers as submodules.

I think that the git clone submodules problems were solved by Maxiwel. It was a permission problems when cloning submodules from outside the Unicamp.

Liana.

[Liana Duenha]

Thank you, Felipe!

[Erwan Moréac]

Hi Liana,

MPSoCBench works well and I have one or two questions if you have the time to answer them. I'm currently studying the platform NoC at because I want to get data payload of the packages injected by IPs in this network.

This purpose led me to  tlm_node.cpp file and tlm_generic_payload variables.

I found functions to use "properly" payload's attributes at this link : https://www.doulos.com/knowhow/systemc/tlm2/tutorial__1/ . The problem is that I cannot say if data I can read on my terminal are good or not.

My question is : Can I know with MPSoCBench all packages at the bit-level sent by all IPs in the NoC during an application ?

Thank you in advance for your answer.

Best regards,

Erwan

[Liana Duenha]

Hi Erwan,

The MPSoCBench uses TLM2.0 to manage communication among processors and IPs. The TLM generic payload encapsulates necessary data (such as: the command, address, and the data pointer) and the communication between SystemC processes is done through function call (using a reference to the payload as a parameter). 

For example, 

The initiator stores data in the payload:

    payload_global->set_address((uint64_t)address);

    payload_global->set_data_length(sizeof(uint8_t));

    payload_global->set_data_ptr(p);

and the target reads from payload:

    uint32_t addr = (uint32_t) payload.get_address();

    unsigned int len = payload.get_data_length();

    unsigned char* data_pointer = payload.get_data_ptr();

So, this communication model does not support packages evaluation at a bit-level.

Best regards,

Liana.

[Erwan Moréac]

Hi Liana,

Thanks for your reply. I think there is something I didn't understand. Your TLM communication used by processors with the NoC, how processors can they realize applications without real data?

The data pointer cannot give us the data used by processors? If yes, we could know the content of each packages, isn't it?

Thank you again for your help, best regards.

Erwan

[Liana Duenha]

Hello Erwan,

The processors execute applications with real data. So,  you can use the data pointer to explore the data transferred between the IPs (memory, for instance) and processors. 

Best regards!

Liana.

[Erwan Moréac]

Hello Liana,

Thanks for your confirmation. In order to get data as soon as they are injected in the noc.at platform, I focused my work in tlm_node.cpp in addToBuffer where the packages are stored in the network.

Here is the function prototype: void tlm_node::addToBuffer (ac_tlm2_payload &p, tlm::tlm_phase& phase, sc_core::sc_time &t)

The payload p is one of the parameters of the function so I used functions to look inside this payload p with the followings lines:
unsigned char*   ptr = p.get_data_ptr();
unsigned int     len = p.get_data_length();
unsigned char*   byt = p.get_byte_enable_ptr();
unsigned int     raw_data = 0;

printf("\nNode %d,%d add package in buffer has %d packages, length %d, payload data : "
,getX(), getY(), getNumberOfPackagesInBuffer(),len);
                if(len > 0){

                    //data recovery with the ptr pointer

                    for(int cpt=(len-1);cpt>=0;cpt--){

                    //data are divided in several bytes that we need to regroup

                        if(cpt < (len-1)){
                            raw_data = raw_data << 8;
                        }
                        raw_data = raw_data + ptr[cpt];
                    }
                    printf("%u ",raw_data);
                    printf("  en hexa %x ",raw_data);
                }

In order to test this data extraction I use this command of MPSoCBench :
./MPSoCBench -p=mips -i=noc.at -n=4 -s=basicmath -b    then,
./MPSoCBench -p=mips -i=noc.at -n=4 -s=basicmath -r

Now this is a screenshot of a short time during the run :

I cannot find any of these numbers read in the output file so I wonder if there are good or not. Should I look the data pointer in the main thread in tlm_node or elsewhere ?

Thank you for the time you take to help me.

Best regards,

Hello Erwan,

It seems that the better place to explore the payload data is in the thread_node method or in the addToBuffer method (as you have done). Both methods are in the tlm_node.cpp file. 

Recently we fixed a bug in the XY routing algorithm and provided the new code in the 2.1 MPSoCBench.

As you are interested in these interconnections resources, it would be better if you download the new version. 

Best regards,

Liana.
