[Comment 1 Hans de Graaff 2016-07-04 18:41:11 UTC]

This happens since the code that tries to determine the processor_count does not have a special case for alpha and none of the default methods work.

I've created a patch using /usr/bin/nproc (as recommended by Tobias on IRC). This has been applied to dev-ruby/concurrent-ruby-1.0.2-r1. I'll create a pull request upstream if this works as expected.

[Comment 2 Tobias Klausmann (RETIRED) 2016-07-05 08:50:04 UTC]

The -r1 variant works fine on alpha. I'll leave this bug open so we can co-track inclusion/fixing of upstream code.

[Comment 3 Hans de Graaff 2016-07-10 05:45:12 UTC]

PR has been accepted upstream.
