-A: Updates of the Linux operating system in 2017 has triggered floating point problems when running AIPS tasks on a new line of Intel Xeon E5-xxx CPUs. This is likely caused by an outdated Intel compiler used to build the AIPS binary install. A GNU compiled version of AIPS 31DEC13 fixes the problem and is available [[ftp://ftp.strw.leidenuniv.nl/pub/intema/spam/AIPS_31DEC13A.tgz|here]]. It may run a bit slower than the Intel compiled version.+A: Updates of the Linux operating system in 2017 has triggered floating point problems when running AIPS tasks on a new line of Intel Xeon E5-xxx CPUs.
