From e042bd9d89670a92e8c0ca44ef5adb6d98659dc7 Mon Sep 17 00:00:00 2001 From: Dan Bonachea Date: Wed, 25 Mar 2020 19:05:13 -0400 Subject: UPC++ 2020.3.0 update (#15623) ## Summary This PR updates and improves the Spack package for [UPC++](https://upcxx.lbl.gov). I'm an LBL employee and developer on the UPC++ team, as well as the maintainer of this Spack package. ### Key Improvements: * Adding new 2020.3.0 release and support for use of develop/master branches - Our build infrastructure underwent a major change in this release, switching from a hand-rolled Python2 script to a bash-based autoconf work-alike. - The new build system is NOT using autotools (nor does it support some of the more esoteric autoconf options), but the user interface for common builds is similar. * Add explicit support for an MPI optional dependency - New `mpi` variant enables use of the MPI-based spawner (most relevant on loosely coupled clusters), and the (unofficial) mpi-conduit backend - This variant is OFF by default, since UPC++ works fine without MPI on many systems, increasing the likelihood first-time Spack users get a working build without needing to correctly setup MPI * Add support for post-install testing using the test support deployed in the new build infrastructure * Fix or workaround a few bugs observed during testing ### Status The new package has been validated with a variety of specs across over seven different systems, including: NERSC cori, ALCF Theta, OLCF Summit, an in-house Linux cluster, and macOS laptops (Mojave and Catalina). --- var/spack/repos/builtin/packages/upcxx/package.py | 109 ++++++++++++++++++++-- 1 file changed, 100 insertions(+), 9 deletions(-) (limited to 'var') diff --git a/var/spack/repos/builtin/packages/upcxx/package.py b/var/spack/repos/builtin/packages/upcxx/package.py index e4806c4c9c..d5c74bebb9 100644 --- a/var/spack/repos/builtin/packages/upcxx/package.py +++ b/var/spack/repos/builtin/packages/upcxx/package.py @@ -10,7 +10,7 @@ def cross_detect(): if spack.architecture.platform().name == 'cray': if which('srun'): return 'cray-aries-slurm' -
