hi Erik, You could try the ones at
https://bitbucket.org/ianhinder/cactusbench/src/faea4e13ed4232968e81edd1bbc80519198fe2b2/examples/ML_BSSN_Test/benchmark/?at=master I haven't updated them in a while, but hopefully the ET is sufficiently backward compatible for them to still work. -- Ian Hinder http://members.aei.mpg.de/ianhin > On 4 Jul 2015, at 17:04, Erik Schnetter <[email protected]> wrote: > >> On Sat, Jul 4, 2015 at 10:21 AM, Ian Hinder <[email protected]> wrote: >> >>> On 3 Jul 2015, at 22:38, Erik Schnetter <[email protected]> wrote: >>> >>> I ran the Simfactory benchmark for ML_BSSN on both the current version and >>> the "rewrite" branch to see whether this branch is ready for production >>> use.
