I'd look for something like this:

regexp {(?i)\d+/\d+/cpu\d+} $a extracted
puts $extracted

Note that the regular expression is in braces, not double-quotes. That is important. (If it was in double quotes, it would have to be "(?i)\\d+/\\d+/cpu\\d+" which is awkward.) Also, I use (?i) to mark it as a case-insensitive regular expression.
