Cilkscreen doesn't work on Fedora 22. I suspect that the Pin tool doesn't like the 4.2 kernel.
$ ~/cilkscreen/cilktools-linux-004225/bin/cilkscreen -- /usr/bin/cat E:4.2 is not a supported linux release $ uname -a Linux ... 4.2.3-200.fc22.x86_64 #1 SMP Thu Oct 8 03:23:55 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
