Roadmap: Release 0.4.0

[memmett]

I think we're getting close to being able to release 0.4.0.

Blockers

• Implement LU decomposition of quadrature matrices. #31 (see Create implicit sweeper that supports LU decomposition of Q. #150) - LU decomp
• (residual-based) iteration control for Boris-SDC #127 - iteration control for Boris
• Split up Declerations and Definitions into separate files #84 - split up decls/impls
• on supercomputers (e.g. JUQUEEN) #173 - getting it up&running on JUQUEEN/JUDGE
• "fix" logging output on MPI-parallelized runs #166 - logging with parallel builds
• Advec-Diff Example: does not finish when number time steps not multiple of number MPI ranks #174 - bug with time step distribution among MPI ranks
• Boris-PFASST with serial spatial solver #180 - Boris-PFASST

Punters

• Enable easy use of profilers (e.g. Scalasca and Tau) #79 - profilers
• Testing Q mat vs. nodes #75 - testing Q vs nodes
• Include convergence tests for mlsdc and pfasst #70 - convergence tests for MLSDC and PFASST
• source and destination of Encapsulation::mat_apply #19 - mat_apply (should this be closed?)

Thoughts? Please move things around if you'd like!

After 0.4.0 I think we should consider a 1.0.0 release.

Thanks for bringing this up, @memmett.

I'll try to tackle #127 and #84 this week.

#19 can be closed and forgotten about for now I think.

I'd like to add another point, which I hope to also tackle this week: Testing PFASST++ on our "little toy machines" JUQUEEN and JUDGE. I'd love to have it up and running for v0.4.0.

Updating above list.

I guess, it's time for wrapping up. Once I've tested the Boris-PFASST stuff more thoroughly (it works! 🎆) I'll create the release branch by end of the week. So we can get the v0.4.0 release out by end of the month without a big hazel.

[memmett]

Sounds good. I will get that LU decomp thinger going... also, I found my GPG keys. Yay.

[memmett]

LU decomp seems to be working. Will wait until Jenkins is happy before checking that one off. Going to push all the 'punters' off to 1.0.

[torbjoernk]

I've just created the release branch. Going to tweak Jenkins a bit to hopefully behave a little better. 😑

Now it's time for a few documentation and cleanup PRs 😃

Plus the Boris-PFASST. Or should we postpone this to v1.0.0? Although 1.0.0 was not intended for new features.

[torbjoernk]

I'm going to tag the first release candidate once #184 and #185 are merged. While doing that I'll prepare the changelog.

Any further points you guys want to see in v0.4.0? I think I'll do the release next week.

[torbjoernk]

The release is out. Now let's concentrate on polishing up the code base for the first milestone release.
