llvm dev - Mar 2015 - [LLVMdev] [Openmp-dev] LLNL wants one of you (as an HPC compiler and tool developer)

Hi everyone,

Colleagues of mine at Lawrence Livermore National Laboratory (LLNL), having seen
the advantages of working closely with LLVM, have decided to toss their hat into
the ring and would like to hire an LLVM-focused compiler engineer. I collaborate
with LLNL regularly, and I'm excited that they're taking this step. I
expect that a qualified applicant will find this position both challenging and
rewarding, and I'd be remiss if I did not mention that LLNL has some of the
largest supercomputers in the world (with more to come:
https://www.llnl.gov/news/next-generation-supercomputer-coming-lab). LLNL runs a
variety of codes on their HPC systems from a variety of science domains, is
transitioning as many of them as possible to very modern C++, and cares deeply
about performance. LLNL is in Livermore, CA (which is on the edge of the San
Francisco Bay area).

  The job posting: http://bit.ly/llnl-job-13027

LLNL's terminology may not make this obvious, but this posting permits
hiring an experienced developer into an advanced job category, as well as for
hiring someone newly graduated.

Please share this with anyone you feel might be interested.

Now for the official text...

If I'm not mistaken Q clearance would require US citizenship. ‎

Hal,
     Out of curiosity. was there any discussion about having the
programmer hired do any work on the nascent llvm fortran compilers
laying around or isn't that on anyone's radar?

Regarding this position, not that I'm aware. However, flang is definitely on
many people's radar. John Leidel (from Micron) and I have created a mailing
list for flang, and we're trying to gather a community there to organize our
efforts:

  https://groups.google.com/forum/?hl=en#!forum/flang-dev

Please subscribe there, and I expect that we'll be having some
development/planning discussions there soon (also, there is a tutorial session
at the upcoming Euro LLVM meeting that I hope will spark some further
development activity).
