As of S2024 Ubuntu 24.04 is becoming the primary Linux.
As of W2019 Ubuntu is now the primary Linux. Login from off-campus with eceTerm.uwaterloo.ca or the use the campus VPN and then log into an eceUbuntu server. Note that the eceTerm.uwaterloo.ca servers are only to be used to then login (ssh -X) to a campus server will the work will be done.
Here is historical server load - Solaris Unix (2005 to 2011) and (CentOS 2011 to 2018)

Scientific Linux (RedHat 7) machines shut down September 2024 and Cadence is now run on RedHat 8. CPUs without AVX2 can not run Matlab R2024+ or Mentor Calibre 2024+
Sun Solaris OS & hardware was used until 2011 peaking at a 30 CPU Sun 6500 machine.
CentOS Linux started to be used in 2009 on Intel Pentium dual-core machines as they offered 10x the performance at 1/10 the power draw.
In F2018 the primary Linux OS became Ubuntu 18.04 LTS because of it's inclusion of current versions of software tools, support of newer CPUs and aprox. 3x the performance in heavily multi-threaded use.
