Introduction

This report describes the progress on the evaluation and extension of MPIP project  from April 10 to April 24, 2003. The main focus of the work during this period was on software and library deloyment.  MPIP, the MeshTV/Silo libaray (Silo only), and the IRS Benchmark have been installed and are working well.  We encountered many problems during this phase that have slowed our progress.  We have solved the mostly configuration problems and are now ready to focus on the major work of the project. We still need to do determine our testing methodology for the IRS benchmark code and also look into how MPIP may be improved.

In the first three sections of the report we detail the steps we have taken in the past two weeks.  Section four details the next steps we will take in the project.

I. mpiP

Task performer

• Nhon Van Nguyen
• Annika Edwards
• Anwar Ali

1. Download & Refenence page: http://www.llnl.gov/CASC/mpip/#Using
2. Step to do:

- Download & extract file: "MPIP_2002_07_08.tar"
- Run: "confgure"
- Change "Makefile" to use "mpicc" compiler
- Run: "make"

Completion: 99%

• Compile and run succesully with MPI matrix multiplier.

Next Steps

• Look into details of all functions and features, how to integrate with IRS.

II. MeshTV/Silo (Need Silo only for IRS application)

Task performer

• Nhon Van Nguyen
• Anwar Ali

1. Download & Reference page: http://www.llnl.gov/meshtv/ (file: "meshtv4_3_1.linux.tar.gz")
2. Follow: "INSTALL_NOTES" - Reference linux part only
3. Modify "configure"
• Change: $CPP to use "gcc" (*Do not use "cpp"*)
• Change all paths "/usr/local/*" to "/usr/*"
4. Mofify "confugure.in"
• Change all path "/usr/local/*" to "/usr/*"
5. Run "configure"
6. Run "make"

Reference to silo library (for this project only)

SILO_LIBS = -lsilo
SILO_LIBPATH = -L/home/nvnguyen/meshtv020506/lib
SILO_INCPATH = -I/home/nvnguyen/meshtv020506/include

 
Completion: 100%

• There are many functions and features of MeshTV/Silo package. For the requirement of IRS "Silo" library is enough.

Next steps

• No further action require for this step.

III. Deloy the IRS Benchmark Code

Task performer

• Nhon Van Nguyen
• Annika Edwards
• Anwar Ali

1. Download & Reference page: http://www.llnl.gov/asci/purple/benchmarks/limited/irs/ (file: "irs1.3.tar")
2. Extract file/untar
3. Go to "scripts" directory , modify all "irs_*" scripts; change the path "#!/usr/local/bin/perl" to "#!/usr/bin/perl"
4. Go to: "build" directory. Modify "Makefile" for the following:
• Silo library path: (See II)
• MPI path:
• MPI_LIBPATH = -L/opt/mpich-1.2.4..8/lib
• MPI_INCPATH = -I/opt/mpich-1.2.4..8/include
• OpenMP path
• OPENMP_LIBPATH = -L/opt/intel/compiler70/ia32/lib
• OPENMP_INCPATH = -I/opt/intel/compiler70/ia32/include
• Change compiler to use "mpicc"
5. Build: make <build-option>
• opt: builds the optimized code
• debug: builds the debug code
• lint: runs lint on the code
• gcc: runs gcc as a syntax checker on the code

Completion: 90%

• IRS application is built successfully with MPI/OpenMP

Next steps

• How to integrate with mpiP
• How to build IRS application with different configuration MPI/OpenMP/mpiP/Threads/Nodes
• Performance measure plan. How/What to collect data to report.

IV. Next Steps

Task performer

• Nhon Van Nguyen

1. We need to determine how we will test MPIP.
   • As mentioned already in section III we need to determine how best to modify the benchmark code for the different senearios we would like to test.
   • If IRS is too difficult to understand in the remaining time, we may need to code our own smaller code to test MPIP.
   
   
2. We will look into the MPIP code to see how we can improve MPIP and impliment this improvement.
