I think GCC 4.7.2 support is still required for IC support isn't it? We have not had a firm decision to retire that yet.

Yeah IC codes confirmed transition to GCC 4.9.3 with a firm kill date of 4.7 for end of January.

[hcedwar]

TODO: Assess how far back we could drop; perhaps gcc 4.8 ?

[crtrott]

Yeah I would go for Intel 15 and GCC 4.8.4 for now.

[nmhamster]

We had been told that the most likely jump would be 17.1 and GCC 4.9.3.

[crtrott]

Yeah thats what IC is doing. Not sure we should go there right away. Also its not clear that the capacity machines are upgrading right away. Looks like those are still on Intel 15.

[hcedwar]

Must be deferred. Reevaluate in April.

If it helps -- one of the issues I've found with GCC 4.7.2 is that lambdas don't quite understand implicit capture. If you capture explicitly, that seems to help.

[hcedwar]

Trilinos is moving to gcc 4.8.4 as the floor version. Time to move floor to gcc 4.8.4 and Intel 15. Drop earlier versions from nightly testing, officially supported lists, and testing scripts. Replace gcc 4.7.2 with gcc 4.8.4 in Jenkins nightly testing.

@crtrott - LAMMPS ok with gcc 4.8.4 and Intel 15 as the floor version?

Verify Titan has CUDA 7.5, then drop CUDA 7.0 as well

Finally I can help with something :) Titan has CUDA-7.5. Please see below… Best, B bjoo@titan-ext5:~> module avail cudatoolkit
