#42379: john-jumbo
-----------------------------+--------------------------------
 Reporter:  macports.ilsa@…  |      Owner:  macports-tickets@…
     Type:  enhancement      |     Status:  new
 Priority:  Normal           |  Milestone:  MacPorts Future
Component:  ports            |    Version:  2.2.1
 Keywords:  john openmp      |       Port:  john-jumbo
-----------------------------+--------------------------------
 john-jumbo is not compiled against openmp, and so doesn't take advantage
 of multiple cores.

 When I run it, Activity Monitor shows john using exactly 100%.  Using the
 OMP_NUM_THREADS variable appears to do nothing.

 Contrast this to what can be found here:  http://openwall.info/wiki/john
 /custom-builds#Compiled-for-Mac-OS-X

 When I run the above version, Activity Manager shows john peaking at
 approximately 750%, which tells me it's taking full advantage of my quad-
 core CPU.  (The benchmark tests are also significantly higher, as would be
 expected) and my fans kick into high gear.

 This is valuable both because it produces results faster, and provides an
 additional source of heat, as my office is a tad chilly. :)
