The version 0.3 was planned for this month, but we haven't yet completed some works, so this version is delayed to the end of August.

The main work in this version is a new job management system, access to simulation distribution feature, and a better integration between the IDE and this job management system. Concretly, this new version will be faster than the 0.2.

Stay tuned …

We are happy to announce that the first stable version of SimExplorer has been published today (see changelog).

Let's download this new version and follow our tutorials? to discover the software.

A new release candidate that adds the undo/redo support in groovy editor #138

Distribution of a data intensive simulation on EGEE (biomed) with the development version of SimExplorer (Workflow version).

data size : 33 MB of data / job

total : 50 GB of results

Note : SimExplorer, provides transparent data compression during file transfers. It hasn't exchanged 50 GB of raw data with the grid.

A simulation of in self propelled has been encapsulated into SimExplorer (workflow version) from a version running on a SGE (Sun Grid Engine) cluster. The integration effort has long last than an hour.

1562 jobs have been executed the following design :

design.addExperimentalFactor(new ExperimentalFactor<BigDecimal>(eta,new RangeBigDecimal("0.0","0.3","0.01")));
design.addExperimentalFactor(new ExperimentalFactor<BigDecimal>(angle,new RangeBigDecimal("0.0","5.0","0.1")));

The launching command is described has follow:

"./follow_me_2d_gaussianNnr 1045674222 1000 4 128 ${eta} ${angle} 50 0.01 1000000 fm_${eta}_${angle}.dat"

Each job runs in 45 minutes. The execution of the 1562 experiments would have require 48,8 day on a single computer (48,8 days / CPU). It has been executed in 9,8 hours on the biomed grid. The crunching factor is 118,7. The bottleneck was the slow Internet connection the experiment has been executed from (1 MB/s upstream speed transfer).

A new release candidate before releasing the final 0.2 soon.

Main Improvements :

• Many IHM bug fix #122 #125 #135 #137
• New plan: Groovy plan to build your own plan
• Add jar to your groovy script
• New font for the groovy editor

download it!

RC7 needs xml application migration. It concerns <GroovyProcessor> nodes. <groovyCode> nodes and <localjars> nodes need to be encapsulated into a <groovyShellProxy> node.

for example:

GroovyProcessor node in RC6

...
<org.simexplorer.methods.processors.GroovyProcessor>
 <metadata>
   <name>GroovyProcessor</name>
 </metadata>
 <state>READY</state>
 <localjars class="linked-list">
     ...
 </localjars>
 <jars class="linked-list"/>
 <groovyCode>
     ...
 </groovyCode>
</org.simexplorer.methods.processors.GroovyProcessor>

GroovyProcessor node in RC7:

...
<org.simexplorer.methods.processors.GroovyProcessor>
 <metadata>
   <name>GroovyProcessor</name>
 </metadata>
 <state>READY</state>
 <groovyShellProxy>
   <localjars class="linked-list">
     ...
   </localjars>
   <groovyCode>
     ...
   </groovyCode>
 </groovyShellProxy>
 <jars class="linked-list"/>
</org.simexplorer.methods.processors.GroovyProcessor>

A new release candidate before releasing the final 0.2 on next week.

Main Improvements :

• Better data structure displaying and editing.
• Better groovy script error
• Information system had broken dependencies
• Empty metadata doesn't make bug
• bugfix in LHS editor
