[libdispatch-dev] Results from running libdispatch tests on Solaris using libkqueue and libdispatch with patches

[Joakim Johansson]

Hi,

If anyone is interested, the output of the working unit tests for libdispatch on Solaris 10 is attached below.

This is done with libdispatch r188 + the patches posted to the list the last few days built together with libkqueue r271 together with a few patches posted on the libkqueue list.

dispatch_priority seems to fail spuriously sometimes (even though it passed in the example below) and the starfish latency boundary test sometimes fails - this is on a Xeon 5500 box with 8 cores (of which 4 is HT).

When running the test suite, a very large number of threads is created for some tests:

386 during dispatch_priority
35 during dispatch_priority2
257 during starfish

It seems a bit excessive, what would be expected on such a configuration not having support for pthread_workqueue?

I will try it using Mark Heily’s userspace pthread_workqueue implementation as well and see how that works.

Joakim
