Charm++ parallel programming system

[Nitin Bhat <nitin.bhat.k AT gmail.com>]

Hi Vishwas,

BigNetSim is an old research project that is no longer supported at Illinois. The more recent software that can perform network simulation is TraceR. 

You can download TraceR by using git clone https://charm.cs.illinois.edu/gerrit/tracer. This link is to download an earlier version. A newer version is developed by Nikhil Jain, an alumnus of PPL at LLNL. You can download the newer version from https://github.com/LLNL/TraceR. 

Let us know if you face any trouble running programs on these versions.

Thanks,

Nitin

Respected sir/madam,

In the conversion of MPI codes to AMPI ,

I followed all the instruction given in the Charm 2007  workshop by taking an MPI program of Matrix multiplication and without making any changes to the code i ran it using /bin/charmc with ' -language ampi  ' flag and inturn got 2 executable files namely charmrun and pgm (name given to the file with -o flag).

My intention is to run it on BigEmulator.

on running the command,(I am running it in my local machine with  single processor)

./charmrun  ++local ./pgm +vp8

I got this response,

------------------------------------------------------------------------------------

wizard@turingmachine:~/temp1/charm/net-linux-x86_64-bigemulator/tests/ampi/mm$ ./charmrun ++local ./pgm +vp8

Missing parameters for BlueGene machine size!

<tip> use command line options: +x, +y, or +z.

However on specifying the +x +y +z parameters along with +bglog to get the trace files,with the following command,

./charmrun ++local ./pgm +x8 +y1 +z1 +vp8 +bglog

I got this response.

I am running it in my laptop, so i don't think there is an issue with some switches.

Am I missing something. I have also attached the mpi program, please sort out the issue.

Thanking you,

Vishwas V.K.
