Satellital Image Clasification with neural networks Step implemented – Final Report Susana Arias, Héctor Gómez UNIVERSIDAD TÉCNICA PARTICULAR DE LOJA ECUADOR Itacuruça – Brazil, november 2 -15, 2008

Final Report Satellital Image Clasification use a neural network for clasification the percentage of land use of a satellite image. Itacuruça – Brazil, november 2 -15, 2008

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 mono.com/download-stable/rhel-4-i386/mono.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. Itacuruça – Brazil, november 2 -15, 2008

Final Report Problems encountered: Execute the commands only like root. rn]$./monos./monos: line 18: /proc/sys/fs/binfmt_misc/register: Permission denied rn]$ sudo./monos –Solution Install mono´s program in the worker node Itacuruça – Brazil, november 2 -15, 2008

Final Report Second Solution We translate the application from.net to C language with MPI libraries. Itacuruça – Brazil, november 2 -15, 2008

Final Report Second Solution Itacuruça – Brazil, november 2 -15, 2008 #include #include "mpi.h" /********** M A I N ******************************************************************************/ int numprocesses, procnum; int main(int nargs, char* argv[]) { NET Net; BOOL Stop; int result=MPI_Init(&nargs, &argv); MPI_ Comm_size(MPI_COMM_WORLD, &numprocesses); // get total number of processes 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 Type = “Job”; JobType = “MPICH”; Executable = “bf”; CPUNumber = 10 ; StdOutput = “output”; StdError = “error”; InputSandbox = {“bf”}; OutputSandbox = {“BPN.txt”}; Itacuruça – Brazil, november 2 -15, 2008

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. BF]$ glite-wms-job-submit -a -o jid bf.jdl BF]$ glite-wms-job-status -i jid BF]$ cd /tmp/jobOutput/app01_776TAA4JvsR-NP2gRkgamA/ BPN.txt NMSE is on Training Set and on Test Set NMSE is on Training Set and on Test Set NMSE is on Training Set and on Test Set Itacuruça – Brazil, november 2 -15, 2008

Final Report Then the application use a Storage Element for read the input files (Satellital Image) and run in the worker nodes. Itacuruça – Brazil, november 2 -15, 2008 JOB GET OUTPUT OUTCOME Output sandbox files for the job: ftNkvfdG3MGA have been successfully retrieved and stored in the directory: /tmp/jobOutput/app01_aUZWfM3V6- ftNkvfdG3MGA 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. Itacuruça – Brazil, november 2 -15, 2008

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. 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 Itacuruça – Brazil, november 2 -15, 2008
