Having problrm regarding `running the program in GPU

[atanuchaudhury]

Tried to run the config file but givving out error in my system. But the same process is running seamlessly in other System. I have installed Clang As well. The problem is given below:

Which code have you tried? Put the code in the 'code' section of github. Also, try to compare the code requirements in your system and the other system. This will help you to figure out the issue.

[atanuchaudhury]

The code is provided in the Git Code Section. The code and system requirements are same as my system and other system. Mainly I am confused about the ‘_ArgTypes’ and error: parameter packs not expanded with ‘...’:

[AstroSuro]

Probably you might need to check the config file and modify it accordingly to overcome the issue.

[atanuchaudhury]

I have done the same process in the other system

[AstroSuro]

Kindly check the compiler version in your system and other system to see if there is any discrepancies.

[atanuchaudhury]

Compared them now. The versions are same but the other system doesnot have openmpi installed.

[AstroSuro]

OpenMpi is not causing the issue.

[atanuchaudhury]

ok

[atanuchaudhury]

can you suggest any other solution

[atanuchaudhury]

I tried some solutions but still getting same issue, such as :

That does not help, at least not in Debian. However, what does help is making the following two changes in /usr/include/c++/*/bits/std_function.h :

Line 433+ (approximate):

template<typename _Functor, typename _Constraints = _Requires<_Callable<_Functor>>> function(_Functor&& __f) //noexcept(_Handler<_Functor>::template _S_nothrow_init<_Functor>()) // CUDA BOTCHES THIS : _Function_base() Line 529+ (approximate):

template _Requires<_Callable<_Functor>, function&> operator=(_Functor&& __f) //noexcept(_Handler<_Functor>::template _S_nothrow_init<_Functor>()) // CUDA BOTCHES THIS { function(std::forward<_Functor>(__f)).swap(this); return this; } Commenting out the indicated part solves the compilation. For some reason, NVCC botches the compilation when that part is present. It preprocesses the C++ code and erroneously changes the template signature in a way that does not and can not compile.

And also tried

install gcc of version 10 helps me: sudo apt install gcc-10 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 sudo update-alternatives --config gcc

choose 10 version while compiling, i also set g++ to 10

I forgot to write what after changing version i removed all files in build directory and begin with start cmake, then make

[atanuchaudhury]

std_function.zip

The problem in the error is showing in the line 435 and 530 as per the error given below

/mpiManager.cpp -o src/communication/mpiManager.o /usr/include/c++/11/bits/std_function.h:435:145: error: parameter packs not expanded with ‘...’: 435 | function(_Functor&& f) | ^ /usr/include/c++/11/bits/std_function.h:435:145: note: ‘_ArgTypes’ /usr/include/c++/11/bits/std_function.h:530:146: error: parameter packs not expanded with ‘...’: 530 | operator=(_Functor&& f) | ^ /usr/include/c++/11/bits/std_function.h:530:146: note: ‘_ArgTypes’

[atanuchaudhury]

It is giving out an error while saving the file

ailed to save 'std_function.h': Unable to write file 'vscode-remote://wsl+ubuntu-22.04/usr/include/c++/11/bits/std_function.h' (NoPermissions (FileSystemError): Error: EACCES: permission denied, open '/usr/include/c++/11/bits/std_function.h')

[atanuchaudhury]

I got the solution from here

https://github.com/NVIDIA/nccl/issues/650

[AstroSuro]

This looks like a read-only file hence you have no permission to edit that. And also in previous comments, it seems you have directly copy pasted the errors from the github page. I need to know what the errors being thrown out when you are executing the code.

[AstroSuro]

I need ssh access to your system. Send the ssh access in the form of username@domain. I need to access your system and run the files to look into the prospective problem.

[AstroSuro]

That does not help, at least not in Debian.

As far as In know, your system is not Debian.

[AstroSuro]

NVCC botches the compilation when that part is present. It preprocesses the C++ code and erroneously changes the template signature in a way that does not and can not compile.

What is the meaning of these lines?

[atanuchaudhury]

ok I will try to creat the ssh

[atanuchaudhury]

I sent a mail making a ssh access in the form of username@domain.

[AstroSuro]

There is no such username@domain mentioned in the email. Kindly understand the requirements. I don't need your ssh key fingerprint. Moreover, you are not supposed to share your ssh key fingerprint with anyone except, if required, you might need to upload that to a remote. I need the ssh address to login to your machine.

[atanuchaudhury]

Are you able to login now?

[atanuchaudhury]

Is there any solution to this error. In the code "std_function.h", the error is showing in line 435 and 530 as parameter packs not expanded with ‘...’

[AstroSuro]

Perform the following actions:

1. sudo apt install openssh-server
2. Edit the SSH configuration file (usually /etc/ssh/sshd_config) to set up the server.
3. Set the following into the sshd_config PermitRootLogin no PasswordAuthentication yes
4. sudo service ssh start
5. WSL ip: ip addr and provide me the ip adr

[AstroSuro]

Provide the path of your code that is generating the problem.

[atanuchaudhury]

Path of the code:

/usr/include/c++/11/bits/std_function.h

[AstroSuro]

std_funtion.h is a header file in the C++ library. I am asking for the code which when executed gives this error.

[atanuchaudhury]

I execute any of the code gives the same error. I saw a solution on github which tells to edit the std_funtion.h header file, it says to coment two lines and save it. I am not able to make changes in the header file.

[atanuchaudhury]

The lines

PermitRootLogin no PasswordAuthentication yes are commented in the code so I need to decomment it right?

[AstroSuro]

are commented in the code so I need to decomment it right?

Yes.

[AstroSuro]

I execute any of the code gives the same error. I saw a solution on github which tells to edit the std_funtion.h header file, it says to coment two lines and save it. I am not able to make changes in the header file.

You are generally not supposed to make any changes in the header files.

[atanuchaudhury]

These is where I found it https://github.com/NVIDIA/nccl/issues/650

and some people are commenting that worked for them

[AstroSuro]

and some people are commenting that worked for them

Doesn't mean that it will work for you. Those are for the advanced users.

[atanuchaudhury]

I tried to change them PermitRootLogin no PasswordAuthentication yes But not able to do by Notepad. Cant save them. What to do??

[AstroSuro]

But not able to do by Notepad. Cant save them. What to do??

Any text editor should be fine.

[atanuchaudhury]

Not working. Cannot save the file. They just create another file but donot save the original one

[AstroSuro]

Not working. Cannot save the file. They just create another file but donot save the original one

Probably learning how to save such a file can be helpful.

[atanuchaudhury]

[AstroSuro]

What is the password for fetchbook@140.114.121.51?

[atanuchaudhury]

[atanuchaudhury]

Done the following

sudo apt install openssh-server Edit the SSH configuration file (usually /etc/ssh/sshd_config) to set up the server. Set the following into the sshd_config PermitRootLogin no PasswordAuthentication yes sudo service ssh start WSL ip: ip addr and provide me the ip adr

[AstroSuro]

Since you have a windows system and a wsl set up at the same time , WSL being the primary working environment for you, I am getting permission denied when I try to see enter the wsl.

[atanuchaudhury]

Its better to use AnyDesk. You will get access to everything.

[AstroSuro]

Maybe

[atanuchaudhury]

Yes definitely. I saw a video where it states that Linux to Linux is most viable but with other systems we face problems

[atanuchaudhury]

You donot have to download Anydesk, you can use it online from browser also.

[atanuchaudhury]

Giving an error. But the file exists in the directory.

[atanuchaudhury]

any solution to this

[AstroSuro]

Please remove the alphabet "I" before C and rerun

[atanuchaudhury]

giving error----- nvcc fatal : Unknown option '-C:/Users/YD/Documents/olb-1.6r0/src'

[AstroSuro]

Remove "-" before the path.
