Hi Ken,

MCE 1.875 was released moments ago. Folks may specify a percentage for max_workers. I enjoyed writing the MCE::Flow test in 03_max_workers.t.

use strict;
use warnings;
use Test::More;

BEGIN {
   use_ok 'MCE';
   use_ok 'MCE::Flow';
}

{
   no warnings 'redefine';
   sub MCE::Util::get_ncpu { return 16; }
}

# ... lots more tests not shown here

{
   MCE::Flow::init(max_workers => [1, '25%']);

   my @res;
   mce_flow { gather => \@res },
       sub { MCE->gather('a'.MCE->task_wid()); },  # 1 worker
       sub { MCE->gather('b'.MCE->task_wid()); };  # 4 workers

   @res = sort @res;
   is("@res", "a1 b1 b2 b3 b4", "check that MCE::Flow ran with 5 worke
+rs");

   MCE::Flow->finish();
}

done_testing;
