Please reconsider support for the new Macs that run Intel Core 2 Duo. Since Macs use a standard CPU and run Unix, it shouldn\'t be too hard to support the new machines, and with each Mac running several CPU\'s all running at 3 GHz, it shouldn\'t take too many before there is a reward for supporting them. I run other BOINC software, but the climate is the MOST important thing to be working on right now. I can\'t get interested in SETI when I think about my grandkids losing their future home to rising sea level.

The problems still are:
1) Macs are only about 2%-3% of the computers used. Including projects that support them. So the support goes where it gets the most results for the effort.
(The program is over a million lines of Fortran, so it\'s not simple to create a version for a new computer type, and it takes months to test each program attempt.)
2) The project has no Mac, but may consider an Intel Mac at some stage, if the finances appear, as they can then use their Intel compiler.
3) There are only 2 programmers, soon to become 1.
4) The scientists want their access programs written and tested, so that they can start to access and analysis the accumulating data.

The problems Les points out are significant but, hopefully, not insurmountable. Most of them are outside our control but I don\'t think it would be hard to get the project an Intel Mac. I don\'t know anyone at Apple to ask but I\'d be happy to make a contribution toward purchasing one. I\'m sure a number of other Mac users would, too. I know Mac users are a minority among possible participants but we could help recruit more of them if there was a client for them to use.

Update: the Boincmgr can\'t connect to the client under crossover. this will need debugging from the crossover standpoint; perhaps some IPC problems? however, i note that genuine windows (tm) folk have also experienced this problem; they reported various issues w/ firewalls, etc. i\'ll see if the source code is illuminating... in any case, i\'m likely to need help from codeweavers to fix this issue.

so, no immediate solution here.

I have tried it with darwine (same source like crossover, but freeware).
The GUI PRC did not work with the boinc manager, but with boinccmd.
I have tried it with SETI, but the performance is painless slow. The emulation eats about to 50 % of one CPU.

Thanks for that information, Dotsch. Another good idea shot down. Pity.

Wish we could accomodate MAC users (which includes my youngest son) but, as Les noted, it isn\'t in the cards for now.

I am still gave it not up.

I am not shure, what the cause of the performance problem is. I will try crossover, too.

In the moment I am testing CDPN with Parallels Desktop. The overhead is smaller. But I am not shure about the performance of CPDN.
What are the typical runtimes for a hadcm model ? - How many TS/s are typical ?

It all depends on the CPU and overall quality of memory, etc. -- also on the parameter mix for a given Model.

At the moment, my machines all run WinXP, three with 32-bit version, three with 64-bit. None in Linux because the TCM is a bit faster in Windoze.
Three A64 X2 4400+ boxes have models ranging from 1.88-1.98 s/TS.
Pentium D 940, Models at 1.89 and 1.90 s/TS.
Core 2 Duo e6600, two Models at 1.54 s/TS.
Pentium IV 2.8GHz + 10% overclock, with Hyperthreading enabled, Models at 4.1 and 4.2 s/TS.

I\'ve no idea how any of that would compare to a MAC.

HTH.

Thank you very much.
I am testing on a Intel Mac with a 2 GHz Core Duo, so your benchs are very good to compare.

Parallels is very slow. Did not made any timestep in some hours, but is still on the CPUs.

But it looks better with CrossOver. But I am still testing.

Les and AstroWX could you please contact me at seti_boinc at dotsch dot de.

Since there is no longer any work available for Macs, am I free to delete my climateprediction.net files? There\'s 160MB of disk space there that I wouldn\'t mind recovering if it\'s no longer useful.

There is a version under development for the Intel MAC only. So, if not one of those, it\'s unlikely there\'ll be a version for your machine in the foreseeable future. Sorry.

Shouldn\'t be anything in the residual CPDN Folder that can\'t be deleted.

I have 2 intel Macs.
How can I find out when the new development is ready?
Thanks

It won\'t be until next year, but I guess that there will be a news item. (You can see these on the front page of this site.)

Tolu has done amazing things with the Intel Mac and will hopefully be making an announcement soon for those interested in a beta tests. Early results look promising -- 1.72 seconds/timestep on the coupled model running on our new ibook (my home PC, a pretty fast P4/3.2GHz, gets 2.15s/ts).

I\'m really happy to hear that there\'s progress at least for the Intel Macs. My MacBook Pro checks every day to see if there is work available. Should I also be watching the news for a beta test announcement?

Please see the mac beta test thread just below this one.

Just moving this thread back to near the top, for those who still run the older Macs.

Yet another reminder: There is NO work available for non-Intel Macs. And never will be.
The older Macs don\'t have the capabilities needed by the newer versions of the climate models.
