[easybuild] Re: [Lmod-users] NAMD license validation

[Robert McLay]

I looked at our namd modulefile and our namd binaries. We do not restrict
access to namd in any way.  Using the userInGroup() function is how we
control access.

[easybuild] Re: [Lmod-users] NAMD license validation

[Robert McLay]

We do the same thing by making the package in a particular group.  We make
the module world readable and use the userInGroup("magic_group") function.
This function returns true if the user is root or the user is in the group
specified.

local err_message = [[
You do not have access to VASP.5.3.5!


Users have to show their licenses and be confirmed by the
VASP team that they are registered users under that license.
Scan a copy of the license and send it to x...@tacc.utexas.edu
]]


if (userInGroup("namd_group")) then
  local vasp_dir="/opt/apps/intel15/mvapich2_2_1/vasp/5.3.5"
  setenv("TACC_VASP_DIR",vasp_dir)
  setenv("TACC_VASP_BIN",pathJoin(vasp_dir,"bin"))
  prepend_path("PATH",pathJoin(vasp_dir,"bin"))
else
   LmodError(err_message,"\n")
end


I hope this helps too!

I don't think that it will be recorded.  The acoustics are usually pretty
bad on the convention floor.  If this changes, I'll let you know. The
slides for the talks will be made available later in the lmod repo.   The
material for the tutorials will also be made available.  The talks will be
at the TACC Booth which is #548.

[easybuild] Lmod Hands on @ TACC Booth Nov 18 2:00-3:30

[Robert McLay]

I will be giving the 5th Annual Lmod Booth BoF at SC 15.  This year Kenneth
Hoste of Easybuild fame has volunteered to give a short talk on:

Why I like Lmod and why you should too!

Then I'll briefly talk about the new features in Lmod.

After that I'll be presenting a Hands on tutorial, where you'll be able to
choose your own topic(s).  Please sign up at the TACC booth. The topics are:


Topic 1:  Using Lmod:

This is topic that introduces Lmod to those who are new to Lmod.

Topic 2:  Using Lmod to create personal modules:

This topic shows you how to leverage a Lmod installation to have
personal modules.

Topic 3: Installing Lmod in a personal account:

This is a way for you to test Lmod before installing system wide.

Topic 4: How to install a System Spider cache:

Lmod can speed up command like "module avail" and "module spider"
with a system spider cache file.

Topic 5: How to write modulefiles for a system.

   How to write meta modules. How to write generic modulefiles.

Any Question?

> The reason that { ... } is being used rather than " ... " is because the

> Curly braces provide another way of grouping information into words.
> They are different from quotes in that no substitutions are performed

> A simple test using tclsh shows that switching to " ... " may cause

>
> $ tclsh
> % puts stderr { foo $bar }
>  foo $bar
> % puts stderr " foo $bar "
> can't read "bar": no such variable
> % puts stderr " foo \$bar "
>  foo $bar
>
>
> So, it's not totally impossible, but it has to be done with great care,
> since it's not just about '$':
>
> % puts stderr " [ expr 2 + 3 ] "
>  5
> % puts stderr { [ expr 2 + 3 ] }
>  [ expr 2 + 3 ]
>
> I'm not sure if there's a way to switch to using " ... " to allow for
> colorized help messages, yet avoid that Tcl tries to evaluate/expand
> substrings.
