From b47e8df089db5f03527528dd8d19478ad8881885 Mon Sep 17 00:00:00 2001 From: Stephan Hoyer Date: Tue, 18 May 2021 09:58:45 -0700 Subject: [PATCH] [JAX-CFD] tweak installation & tests The tweaks to the test suite ensure everything passes on my local installation on my MacBook, and shave a few minutes off the execution time. If the README instructions are followed, the whole test-suite runs in about two and a half minutes on my Mac. It excludes the "validation tests", which are too slow to run on CPU.
