Thanks for posting. As it happens, the management already know.

There are perhaps some factors you are overlooking:

First, the vast majority of Unix computers are not in private hands. They belong to corporations, and that isn't the main target for WCG recruitment. Other grid projects attempt to harness this power more effectively.

Second, Unix servers are nearly always running critical applications and services. Running grid software on them would often be irresponsible.

Third, since there are so many Unixes, porting WCG to them all would require more work than porting to Windows, Linux and Mac combined. Already WCG have hit the wall of diminishing returns. The high demand for Mac support led to that being added, but so far Macs account for a tiny minority of WCG hosts. The Mac Intel platform is an even tinier subset of that. But WCG added the support because they expect the platform to grow, and they expect to be able to make significant recruitment headway there. This argument doesn't apply to Unix.

Finally, WCG haven't ruled out adding Unix support. But it is a very, very low priority.

And the last word: if you have a huge untapped computing resource that you are personally responsible for, then contact WCG directly. If you can deliver a few (hundreds of) thousands of computers, then that will provide plenty of motivation to add a new platform. Still, WCG would prefer you to run the agent on thousands of corporate desktops than thousands of corporate servers.

There is a table on the unofficial BOINC wiki that shows which platforms a project runs on......

I used to run SETI classic, and a bit ot SETI/BOINC until it moved to version 5 and now it can't get any more work from the project. There is also the RC5-72 codebreaking project that runs on AIX but I am wondering if anything more useful can be found until someting like WCG is available. Not necessarily a BOINC project, just anything that does useful work.

Compliant? Do tell... is there a standard?

edit: Just to be clear, I am aware of the Last-Modified header. However, it is difficult to use with dynamically generated pages, because it has no implicit meaning. Since it's not used for anything except perhaps cache management, there's little point trying to make it more meaningful.
