Reported in Latest News and Announcements by MO.V:-
There's good news for Mac users. HadAM3P ran much more slowly on Mac than on Windows and Linux. Tolu has released a new 6.07 version of this model for Mac. It uses a different compiler and should run faster than version 6.06. It will still be helpful to CPDN if members can complete their current HadAM3P models before downloading new ones as they all produce good data for the researchers.

Does this mean Macs can now run these tasks without them bombing out as they had done previously through an incompatible Fortran compiler?
Please clear this for me and I will change my preferences to accept HadAM3P in future.

I look forward to a reply confiming that, as I am sure, are many others.

When Tolu released v.6.07 on the CPDN Beta project for testing the CPDN Coordinator Hiro Yamazaki told me 'Tolu has just released a new HadAM3P for mac on the beta site to address the performance issue. I believe he has used gfortran instead of intel compiler.' (I don't think Hiro will mind me quoting that.)

One of Keith's crashed HadAM3Ps is here. Perhaps someone more knowledgeable than me could look at the error messages to see whether the problem is just the compiler for this model type.

The problem previously was that a different Fortran compiler had been used for some types of task and another with other types.
It turned out that once the first task had been run, the program only would accept tasks of the same type (unless BOINC was reset and started with one of the other type of tasks, when only that type would be accepted).

I hope you understand that, and that I am relating the story correctly as I understand it.

You will notice that earlier on I was having every task being bombed out until I was advised to be selective in the preferences to avoid those that were problems.

I am hoping that I can now add back HadAM3P in my Preferences.

OK, now I see what you mean! Sorry!

Could you select HadAM3P only again, see what happens when you run one and please let us know.

OK. Have done that by aborting one task which had been recently downloaded but not yet started.
After loading and eventually crunching, it has happily run for over 15 minutes.
It never managed as much as 5 minutes before, so I assume all is OK. (We shall see.)

As you will notice, I was successfully running these early in April until I did the recommended reset.
After that they dropped out almost immediately on starting crunching.

I will let you know if any further problems arise after resetting preferences to accept HADSM3 and HADSM Mid-Holocene again together with HADAM3P (all now running on different version numbered apps 6.09, 6.04, 6.07).

I shall also reinstate HADCM3, which I also used to run successfully until they started to drop out (due I had assumed, to the Fortran problem).

I was disappointed when I could no longer run those long tasks and will be glad if they are now available to me again.

I will report any problems that may arise.

HADam3P has been running for 8hrs 30 mins and seems OK., except that "Show Graphics" is completely unresponsive in either Simple View or in Advanced View.

Is that normal with the new app using NIVIDIA GPU, as mine uses RadeonX1600?

EDIT: HAVE JUST RESTARTED AFTER JAVA UPDATE AND NOW "SHOW GRAPHICS" WORKS NORMALLY

Had first trickle through.
Fantastic. As promised 50% + improvement.
The s/TS has dropped from 9.1691 on my last successful task to 5.9795 this time.
So should finish in 4 days instead of 6 days. We shall see.

But the main thing is that it has successfully kept going without crashing this time.

I have an HADCM3 istd task scheduled to crunch in 3 days time.
I was looking forward to that being a success after so many previous failures.
The outcome had always ended, after several repeats of same details, the following report:-

However, it is still running the app version 6.04, so I suspect I will still have the same problem.
If you have any comments about this before crunching starts, they would be appreciated.

To keep you in picture as to progress. Successful crunching (70% so far) of HADAM3P task.
And I shall eventually try each of the four tasks available for my Mac.
I shall be so glad then hopefully to be able to crunch all 4 on my MacBookPro Intel.

Only the HadAM3P models have been 'upgraded'. The HADCM3 models are the same as before.

As promised, I report that the HADAM3Pmnjs task has completed, but surprisingly has not been granted full credit (may be just delayed?).

And the HADCMistd task shows no improvement (as feared)
It crashed immediately after starting , and the messages are shown below:-

The problem will be the insufficient shared memory. Macs seem to have plenty of it for single-core machines but not for multi-cores. I can't understand why they don't configure this more sensibly at the manufacturing stage because it's been a known problem for quite a long time. If you have two models running simultaneously and both reach a checkpoint at the same time I'd guess that this causes at least one model to crash.

A tried and tested solution is explained here by Eric Myers.

Macs seem to be getting a 40% decrease in processing time on 3P tasks. Great.

They are also getting a 20% decrease in credits awarded. Not so great.

Hi Billy

A completed HadAM3P should earn 1982 credits whichever platform it's crunched on. Sometimes I think the credits for the last few days of the model don't get included (I don't know why) and then the model gets 1980. Zombie67 tested the new Mac version on CPDN Beta and got 1980 credits. Are members getting fewer than this for completed HadAM3Ps on the main project?

Temporarily, yes, but only for a couple of models completed and reported today - for the time being, they're showing the (lower) benchmark * time BOINC claim, and the amount awarded for whatever trickle they'd reached the last time the credit process was run - I think we lost a run when climateapps2 was down on Wednesday.

All tasks reported long enough ago to have had a complete credit run since reporting are showing the expected 1,982.64 for both claim and grant - most recent 22 June.

It is no question of reaching a check point.
In spite of having successfully completed twice as I have indicated, never have I been able to even start crunching since then ---- No crunching, no checkpoint -- just crashes immediately it's turn comes to start crunching. I had thought it was related to the old problem of the apps being compiled from 2 different versions of fortran, but this would not now appear to be the case. I will see if I can follow Eric Myers solution.
I will make sure that my next task to be downloaded will be expedited as soon as I have made the necessary adjustments.
