ARGOMENTO:

We've updated the openMalariaBeta Windows and Mac versions to 6.33 today, and are currently sending out a small test batch targeted at these operating systems. 6.33 differs from 6.32 in that we have added some more log messages, which should help us tackle the problems with checkpointing.

We have not released Linux versions 6.33 so far. The reason is that we've run into a problem with the Linux build: Our application relies on a number of software libraries developed by others. We use these libraries to help us with tasks like the parsing of the input files, sampling of random numbers, or compressing the result files before sending them back to the server. We now face the problem that some of these libraries require us to use a recent Linux distribution to build the application - in the past we always used fairly dated distributions to prevent problems when the application was run on a computer with an older Linux. We're now trying to get a running Linux version that will support as wide a range of hosts as possible.

We've configured our BOINC server so that it should send work only to computers which can run version 6.33, this way we wanted to prevent workunits being sent to Linux hosts until we can do something about the library dependency problems.
It seems this is not working perfectly - some Linux hosts get work even though they can only use version 6.32 (and therefore all workunits crash), and others get misleading messages from the scheduler (like "not enough disk space"). Not sure why this is, but we're looking into it.
<Edit>
Could be that older BOINC clients don't report the application version when requesting work?

Per ora niente lavoro su Linux, se ho capito bene...

Esatto... Qualche wu riesce lo stesso ad arrivare ai pc linux ma ovviamente crasha, perchè non dovrebbe arrivarci.

Comunque io non ho visto lavoro neanche su windows, da dopo il pentathlon...

Perfetto io ho linux quindi niente da fare peccato.

Facci sapere se ricevi qualche WU, quando succederà...

Ad ora cioè 24 maggio ancora niente

In questi giorni anche chi ha windows è fermo...

speriamo che si ripiglino in fretta.

Io ho abilitato l'opzione Run test applications, forse sono WU di test... comunque sono nominate openMalaria test version v6.38

Update June 2010

In May we started testing our new science application which includes several new features. After fixing some problems with software library dependencies (discussed here) and testing new binaries we are able to reduce the failure rate to an acceptable level: more than 90% of the workunits now run successfully on mac and windows. This week we deployed one more version of the application (6.41). This includes some minor changes and improvements and a new model for case-management.

More importantly, we now have prepared the input data files that we will need to launch the next phase of model optimization (see previous update). These new workunits are slightly different in their system requirements than previous ones. The simulations demand more memory. Therefore, the checkpoints will also use more disk space. We are aware that this may lead to problems on some older hardware, but there is currently no way to change this: checkpointing only works if we can save all of the relevant values to disk.

So far, the results we get back for the new workunits look OK, and we plan to deploy this as our new main science application next week for the win and mac versions at least. We are aware that there are still a few issues with the validation of the results. For a low proportion of results, we see that the outcomes differ despite the fact that the workunit ran successfully and led to an output file being uploaded. We are investigating this, but so far are having difficulties reproducing these problems. Whenever we re-run such a workunit on our computers here, we get the same outcome as the �valid� result on malariacontrol.net.

Finally, we would like to point you to another scientific article which was recently published, and which is based on some of the runs that you helped us with during late summer 2009. The study investigates the effect of differences between human individuals on malaria epidemiology in endemic countries. As you know, individuals differ from one to another. This is the case for a malaria endemic community too. Some will not seek any treatment; others will go to the clinic when the first fever appears. This type of heterogeneity and others such as transmission and risk of co-morbidity were introduced in the simulation to see how it affects patterns of illness and deaths.

Postata proprio ieri

Sono WU test e dovete abilitare lo scaccolamento tra le preferenze del progetto nella vostra user page di Malaria

Per Linux stanno cercando una soluzione

tanto che mi lamentavo mi ero dimenticato di mettere su yes la voce "run test applications"

Adesso mi ha scaricato 2 wu

Infatti ieri ne ho fatto una scorpacciata...

Confermo che sono le 6.41...

Sotto coi criceti!

EDIT:

Ho verificato le mie 20 WU finite tra ieri e oggi: 7 (35%) sono andate in errore, d'altronde servono per aggiustare il tiro...

Quindi se avete una percentuale simile non preoccupatevi...

Con l'avvento della versione 6.42 (e la fine della versione test 6.41) sono sei giorni che non accuso WU fallate sul progetto!
