prerequisites of ET installation
by Panagiotis Iosif 27 Jan '23

27 Jan '23

Dear ET users, I am following the CactusTutorial.ipynb notebook to install ET in a workstation in my institute. Among the prerequisites there is the "python-is-python3" package which symlinks /usr/bin/python to python3. The workstation has a slightly older Ubuntu version installed (18.04 LTS) and does not find this particular package for installation. I do not have rights to perform a system upgrade / or install a newer Ubuntu version. Is it safe to omit this package from the prerequisites? Are there elements in ET that are possible to "break" if this is left out? Is there a workaround, for example should I do the symlink to python3 manually? Thanks and best regards, Panagiotis Iosif ------------------------------------------------------------- Dr. Panagiotis Iosif postdoctoral researcher email: piosif(a)auth.gr; paniosif(a)gmail.com Section of Astrophysics, Astronomy and Mechanics Department of Physics Aristotle University of Thessaloniki 54124, Thessaloniki, Greece -------------------------------------------------------------

An email will be sent out to reach out to the contributors. SSL Cert for the mailing list archives. The URL for the testing system will probably work by next. The first version of the ET swag shop is up: https://www.etsy.com/shop/EinsteinToolkitShop Please send comments / thoughts / suggestions to sbrandt(a)cct.lsu.edu ET Meeting in Europe June 19-23 at the University Aveiro in Portugal. The testsuite system needs a reviewer. Majority of CCTK_REAL is used in the ET, but a float would break many of the thorns. We should start testing this feature. There is a CCTK_REAL8. CCTK_PRECISION can be set in the OptionList. Various tickets are ready for review. Didn't look at all of these. https://bitbucket.org/cactuscode/cactus/pull-requests/145/implement-scalars… Next week: Peter Diener, famed in song and story, shall be chair!

Fwd: Master opportunity at University of Milan Bicocca
by Bruno Giacomazzo 17 Jan '23

17 Jan '23

Dear All, the University of Milano-Bicocca has recently launched a new international master in astrophysics. The department now features a large faculty covering subjects spanning from GW and compact objects to high redshift galaxies and CMB experiments and, consequently, a Master with a rich program. The master also includes a course on numerical relativity by me that makes also use of the Einstein Toolkit. On January 24 there will be an online open day dedicated to the master. All info are in the attached flyer. Please share it with any student who might be interested. More information on the astrophysics group at Milano-Bicocca can be found here: https://astro.fisica.unimib.it/ More information on the University of Milano-Bicocca can be found here: https://en.unimib.it/ Cheers, Bruno -- Prof. Bruno Giacomazzo Department of Physics University of Milano-Bicocca Piazza della Scienza 3 20126 Milano Italy email: bruno.giacomazzo(a)unimib.it phone: (+39) 02 6448 2321 web: http://www.brunogiacomazzo.org --------------------------------------------------------------------- There are only 10 types of people in the world: Those who understand binary, and those who don't ----------------------------------------------------------------------
