-ECE staff also administer Linux and Solaris servers for research use. ECE research users on any network tier may be assigned a login account by their supervisor on any network tier on these (tier 1) managed systems for research computing, including networked storage with archival backups, and for running Linux or Solaris software applications such as Cadence, Verilog, etc. and compiling user source code.

ECE research users on any network tier may be assigned a login account by their supervisor on any network tier on these (tier 1) managed systems for research computing. A login account provides email, networked storage with archival backups, and allows running Linux or Solaris software applications such as Cadence, Verilog, etc.  on Tier 1 linux hosts, and compiling user source code. Each assigned user login is charged back to the user's supervisor each month while the account remains open.

-ECE provides full-time support staff for research computing (as of fall 2016, six full-time staff). Part of the cost of these services, and some pooled costs for network software licenses, are recovered through charge-backs to each ECE research professor based on the number of PCs on staff-managed networks (tier 1 & 2); number user login accounts on staff-managed servers; and for users without either of these assigned, a modest minimum charge per supervised research group member (grads, postdocs, RAs, techs and visitors/casuals). Each professor is assessed one 'tier 3/wireless only user' fee for each supervisee who is not assigned a billable Tier 1/Tier 2 PC or user login account. (We sometimes refer to this for brevity as a 'tier 3 fee', though it is applicable to any supervisee whether their supervisor does or does not operate a //tier 3 network//.)+ECE provides full-time support staff for research computing (as of fall 2016, six full-time staff).
