Final Report
• Satellital Image Clasification use a neural network for clasification the percentage of land use of a satellite image.

Final Report
First Solution
● We decide to compiler the windows's application in
Linux, for that We use a mono's program (C#
interface for Linux).
1. Create info about mono repository: cd /etc/yum.repos.d
2. Download and install: wget
http://www.go-mono.com/download-stable/rhel-4-i386/mo
no.repo
3. We sure Linux kernel can run Mono applications
"natively" (like Windows), without using "mono" every
time. Following these directions, We create a script.

Final Report
• Problems encountered:
Execute the commands only like root.
[alumno@m150-e2gris1 rn]$ ./monos
./monos: line 18: /proc/sys/fs/binfmt_misc/register: Permission denied
[alumno@m150-e2gris1 rn]$ sudo ./monos
– Solution
Install mono´s program in the worker node

Final Report
Second Solution
• We translate the application from .net to C language with MPI libraries.

MPI_Comm_rank(MPI_COMM_WORLD, &procnum); // get process number for this process
file bf.c
Final Report● Then we compiler MPI en UI, $ mpiCC● Compiler our application, $ mpiCC -o bf bf.c● Then create a .jdl

Final Report•We compiler bf.c ONLY in the 64 bits machine, do not compiler the machine in 32 bits because do not have installed MPI.
[app01@m111-e2gris1 BF]$ glite-wms-job-submit -a -o jid bf.jdl

NMSE is 0.106 on Training Set and 0.133 on Test Set
NMSE is 0.105 on Training Set and 0.129 on Test Set
NMSE is 0.104 on Training Set and 0.128 on Test Set

Final Report•Then the application use a Storage Element for read the input files
(Satellital Image) and run in the worker nodes.

JOB GET OUTPUT OUTCOME
Output sandbox files for the job:https://m05-e2gris1.eela.ufrj.br:9000/aUZWfM3V6-ftNkvfdG3MGAhave been successfully retrieved and stored in the directory:/tmp/jobOutput/app01_aUZWfM3V6-ftNkvfdG3MGA
[app01@m111-e2gris1 app01_aUZWfM3V6-ftNkvfdG3MGA]$ ls
BPN.txt error output watchdog.log
Final Report•Finally We use a GENIUS portal for submit the jobs, not with MPI.

Final Report: MrBayes As the same time, We worked in another
application like Mrbayes (bionformatics), We install mrbayes at the UI, and We try to run mrbayes with condor, but it was not possible because there was not condor in the CE, finally We saw how to mrbyes runs with mpi and find out how to put some directives to run in the WN.
www.eu-eela.eu Itacuruça – Brazil, november 2 -15, 2008
Final Report: MrBayes
•We send MrBayes application to GENIUS
portal.
• Normally the time for run is 2 weeks, in 1
CPU, and the output files is a string
sequence of 360GB
