How to use the GPU server

Computer Center has three operational GPU servers with Nvidia Tesla A40, A100 and S1070 GPU cards.

• gpu01.cc.iitk.ac.in ( IP address: 172.31.1.83)
• gpu02.cc.iitk.ac.in ( IP address: 172.31.1.84)
• gpu03.cc.iitk.ac.in ( IP address: 172.31.1.85)
• gpu04.cc.iitk.ac.in ( IP address: 172.31.1.86)

As per present policy gpu01, gpu02, gpu03, and gpu04 servers can be accessed by any user with a shell account by logging in via ssh (X-11 forwarding enabled).

	# ssh <IITK-username>@<server-name> -X 
	e.g. ssh soumitri@gpu01.cc.iitk.ac.in -X

The following "hello world" program may help you in getting started with CUDA compiler to compile a program. Please note this program does not use cuda cores.

	$ vi helloworld.cu
	-------------------------------
	$include "stdio.h"
	int main()
		{
		printf("Hello, world\n");
		return 0;
		}
	-------------------------------
	$ nvcc -o helloworld helloworld.cu
	$./helloworld

With the above sample C program, CUDA compiler is used to compile it. Use nvcc to compile programs which has CUDA functionality.
