Maxime,
I agree that the current toolchain version numbering is quite confusing.
One question about date numbering: what if somebody wants to downgrade 
one of the toolchain elements? Maybe a micro version number would 
still be useful for this task.


Toolchain versioning is bound to always be confusing, whatever the 
choices are. A micro-version number won't solve the question... which 
element of the toolchain was downgraded (or upgraded) ?  My claim is 
that date numbering makes more sense than incremental version 
numbering... not that it makes actual sense. Lesser of two evils.


That, in fact, is precisely why I'm against exposing toolchains to 
users. Toolchains are a necessary burden because of the way EasyBuild is 
made, but are very awkward for users  (not even mentioning their obscure 
naming...)


Cheers,

Maxime

Eliot,
please proceed with the pull request whenever you want.
I am currently on hold until I get some advice on how to deal with naming MPI 
easyconfigs for different networks.
I will be happy to test your pull whenever available.

My builds all look good, so I'm ready to submit the pull request. Or were you

I was hoping Kenneth would jump in and tell us if we're right or wrong. We can 
always adjust before he merges.

Eliot,

I started working on the same toolchain and I have the same problem since the 
toolchain version numbering is not very clear. The temporary number I chose is 
3.1.10 for the following reasons:


  *   Since one of the elements got a major update (i.e. CUDA), I bumped the 
toolchain major version to 3
  *   Since GCC got only a minor update with respect to gcccuda-2.6.10, I set 
the minor version to 1
  *   I set the tiny version to 10 to allow other users to downgrade if needed


That was what came out from my personal interpretation of the toolchain version 
rules, but I could be completely wrong.

Hi Folks,

I could use help with version numbering on a new toolchain.

I manage a GPU cluster and am in the process of adding support for newer
versions of CUDA. I'm working on CUDA 7.5 along with the FOSS tools from
foss/2016a. When CUDA 8.0 comes out (soon) it can be paired with foss/2016b.

The existing toolchain is gcccuda-2.6.10, which includes CUDA 5.5 and
GCC 4.8.2. I'm talking about moving to CUDA 7.5 and GCC 4.9.3-2.25.

In that context, what version number should I give gcccuda? If CUDA 5
was major version 2, then CUDA 6 would be version 3 and CUDA 7 would be
version 4? Bump up to gcccuda-4.0.0? And to gcccuda-5.0.0 when CUDA 8.0
comes out?

Once this is settled I'll submit pull requests on github for gcccuda,
gompic, and goolfc with the newer version of CUDA and suitable GCC,
OpenMPI, etc.

Thanks!
Eliot

Re: [easybuild] Version numbering for new CUDA toolchain

2016-08-24 Thread Eliot Eshelman 
Agreed! I know the CPU-only toolchains have gone to date-based 
numbering. I'd be happy to switch this, too!


I recommend we call this 2016.08. By the time CUDA 8.0 comes out, we'll 
be able to call that one 2016.09.

Hi everyone,
What is the point of versioning toolchains with an absolute number 
that is meaningless (what would "version 3" actually mean is anybody's 
guess).


While I think versioning toolchains will always be somewhat awkward, I 
think numbering it according to a date (or year) of release is what 
makes most sense.


Just my two cents.
