1. EDAGRID TUTORIAL Dr. Tuan-Anh Nguyen Ho Chi Minh City University of Technology Prof. Pierre Kuonen University of Applied Sciences of Fribourg, Switzerland

2. Overview  First part: EDAGrid middleware How to use EDAGrid middleware to submit jobs How to describe a job flow  Part two: EDAGrid programming Writing a simple Grid program with POP- C++ Executing the program on EDAGrid

3. Supercomputer PC Supercomputer My laptop Workstation SMP Cluster The Grid environment ?

4. EDAGrid infrastructure: Objectives  Middleware for computing Grid Execute parallel applications transparently with a QoS of resources  Use case User EDAGrid middleware “Execute my app on 4 processors with at least 500MFlops and 1GB/s network”

5. Login  User name: acomp2007  Password: guess  Create a subdirectory mkdir cd  Server information: Grid FTP server  gsiftp://serverkstn.cse.hcmut.edu.vn:2811 Your home: /home/acomp2007

6. Describe jobs  XML based job descriptions Resource characteristics Application characteristics Staging description... A single job description Number of CPUs How many CPU each node Linpack benchmark Network bandwidth... Where are executables Agruments Compatible platforms How to stage in/out data...

7. Describe a simple job 1 /bin/sleep 10  Edit job.xml:  Submit the job eda_job_submit -w job.xml

8. Resource requirement  Add resource requirement to the job description 100MFlops but at least 60MFlops is also acceptable Physical memory of at lease 256MB 1 100 256 /bin/sleep 10  NetworkBandwidth (MBit/s)  IndividualCPUFree5 (0...1)  IndividualCPUFree10 (0...1)  IndividualCPUFree15 (0...1)  IndividualCPUCount

9. Stage data in/out  gsiftp://serverkstn.cse.hcmut.edu.vn:2811  Sort data....... 1 gsiftp://serverkstn.cse.hcmut.edu.vn:2811/PATH_TO_YOUR_FILE file:///${GLOBUS_USER_HOME}/data file:///$ /bin/sort ${GLOBUS_USER_HOME}/data --output=${GLOBUS_USER_HOME}/result file:///${GLOBUS_USER_HOME}/result file:///$ gsiftp://serverkstn.cse.hcmut.edu.vn:2811/PATH_TO_YOUR_OUTPUT...

10. Describe a multijob workflow... Job 1 Job 2 Job 3

11. Parallel sort.... split data sort 2 sort 1 mer ge result... Note: - To sort (all platforms): /bin/sort -output= - To merge (all platforms): /bin/sort -merge -output= - To split (only available on YOUR machine): /home/edagrid/demo/splittext
