Sorry, didn’t find time earlier.

Ehm, I think I did not even port SomAll. That’s an empty class?

> No, SomPageRank doesn't run on Pharo either. It gets into an infinite loop, because #generateRandomPagesN:outLinks:divisor: is evaluated with n = 1, and that makes the following loop infinite:

That’s a bug in the original code. Yes. I didn’t fix it.

Not sure how you even execute the code, since I didn’t document anything… Sorry.
But, the general idea is to execute it from the command line.

From within the image, you can execute it with:
   SomBenchmarkHarness new run: { ''. 'PageRank'. '10'. '0'. ‘5' }.

On the command line it would look something like:
   $yourVM $yourImage SomBenchmarkHarness  PageRank 500 0 1

(Assuming that the Scripting package is loaded).
Sorry, am currently traveling. Will try to create a proper configuration when I am back.

Best regards
Stefan
