how to find out about platform, cpu info etc.

nasridine · 01-21-2010, 12:24 AM

I was trying to compile some code on a remote machine. It asks for following information
Machine:
CPU type:
Operation system:
Fortran compiler:
C compiler:

Where can I find out what they are and where these compilers are installed? thanks in advance.

The answer varies wildly depending on:

a) the machine
b) the compilers
c) the "it" that's asking you for this information (and what, exactly, "it" might be expecting to find)

Suggestion: talk to the administrator who gave you access to the remote machine. He/she might be able to help.

If the remote machine is Linux, you could probably also do worse than typing:

d) uname -a
e) gcc -v
f) gfortran -v

lscpu will give you CPU info. Along with the commands paulsm4 already suggested will give you all of the info you should need.

Also you might take a look at one of the sysinfo scripts like http://gsysinfo.sourceforge.net/ or http://code.google.com/p/inxi/

In the Makefile of that software I was compiling, there are these choices for fortran compiler:
IBM, Intel, SUN, HP, GNU g77, gnu gfortran, PGI. It seems gfortran is just one of them. Is there way to know which fortran compiler is being used by the remote machine?
