From 749508af010ee90009a61bb42a8f8214a6fabd21 Mon Sep 17 00:00:00 2001 From: Mario Melara Date: Wed, 6 Apr 2016 12:05:29 -0700 Subject: Found loops calling all_compilers that were always reading in the config file which lead to a slowdown, the fix is to cache the config file so we don't waste time re-reading the config file in again. --- lib/spack/spack/compilers/__init__.py | 17 +++++++++++------ 1 file changed, 11 insertions(+), 6 deletions(-) (limited to 'lib') diff --git a/lib/spack/spack/compilers/__init__.py b/lib/spack/spack/compilers/__init__.py index 9601ae3e3a..caf438e232 100644 --- a/lib/spack/spack/compilers/__init__.py +++ b/lib/spack/spack/compilers/__init__.py @@ -151,20 +151,25 @@ def remove_compiler_from_config(compiler_spec, arch=None, scope=None): spack.config.update_config('compilers', update, scope) +_cache_config_file = {} def all_compilers_config(arch=None, scope=None): """Return a set of specs for all the compiler versions currently available to build with.
