Snow is falling here, which screwed up my plans (for working outside). And I have time to do other things, like getting Climate Prediction working again. After moving and hardware upgrades.

A year ago, I updated hardware which seemed to make having ClimatePrediction restart unusual. Unusual for the people writing the BOINC modules. So, nothing ever got downloaded. Les Bayliss (sp?) has mentioned 32 bit requirements for AMD64 machines. I am running Debian, and multiarchticture is present here. And has been for quite a while.

Since the hardware change 6 months ago or so, the project directory in /var has been empty. Not surprisingly, this means no ClimatePrediction jobs are running.

With the recent (much earlier than expected) snow, I have had time to add various 32 bit libraries to my amd64 machine. And Climate Prediction has still not started any jobs, or added any content to .../projects/... so that I could at least run ldd to look for more missing 32 bit libraries.

Maybe benchmarks are needed. So, I had BOINC Manager redo benchmarks. Still no change (no BOINC jobs, no messages in the log to indicate why).

Today, I told BOINC Manager to remove Climate Prediction, and then I added it back in. Just the same as before. No content to the .../Projects/... directory, no jobs listed, no storage taken, nothing noted in the BOINC log.

My foo has run out. I don't know what else is needed to find out what is missing to get jobs (if they are available) to download.

What am I doing wrong?

I recently posted things vaguely similar, and a search here produced nothing? Not even what I posted.

The work comes out in batches currently, which don't always last very long. At the moment the job queue is empty, so your machine won't get any work even if the 32-bit configuration is correct.

If new work comes out I'll try to remember to post a message in this thread so you can download some work to test your new setup.

... that didn't take long. There are a few hundred work units in the queue now.

I just woke up, and put in my request for a unit or two.

Well, something was downloaded. Now I can see if things will work, or what else is missing.

191 MB of wah2*zip and gz files.

One wah2*zip file has data in the name, it contains datain and jobs directories full of various files.

Three wah2_eu*zip files. One of those files has namelists, stashc and a cpdc files. I presume the other 2 are similar.

One wah2_se*zip file which contains a shared object library. Or perhaps a person should say it is a wah2*8.12_i686-pc-linux-gnu.zip file, with se in the name.

There are 2 other i686 zips, with am and rm in the fname. They contain a single file, nominally the same as the name of the archive (minus the zip extension).

Running ldd against the shared object library, it lists 8 objects. The 6 in the middle are of the form
name => path
and the path involves a 32 bit designation, and does exist on this computer. The last object is just /lib/ld-linux.so.2 (no 32 bit designation in path, but a 32 bit ld-linux does exist on machine). The first object is
linux-gate.so.1
which does not exist on this computer, and is not listed in any Debian package. I presume this is part of ClimaePrediction?

Running ldd against the wah2am file, it sees 6 objects, the middle 4 are found with 32 bit indications in the path, the first and last same as the shared object.

And the wah2rm file is nominally the same as the wah2am file.

Ah, I see that linux-gate is a facility provided by the kernel.

http://stackoverflow.com/questions/19981862/what-are-ld-linux-so-2-and-linux-gate-so-1

So, everything appears to be resolved in the zip files I looked at.

And checking the BOINC manager, I see that 3 instances are off and running. ETA is only 3.5 days each. :-)
