Charm++ parallel programming system

["Bhat, Nitin" <nbhat4 AT illinois.edu>]

Hi Sutirtha,

 

From your error files, it looks like you’re trying to build a verbs build of Charm++ on a machine where Infiniband Verbs (a network layer software package) is not installed. Which machine are you trying to build Charm++ on? Is this a local linux machine (like a laptop or a desktop) or a cluster/supercomputer with Infiniband network?

 

If it’s a cluster (or a supercomputer) with Infiniband network, you can ask your System Administrator to install Verbs and then build Charm++ on top of that using your original build command (./build charm++  verbs-linux-x86_64 gcc --with-production).

 

If it’s a local machine or any other cluster without a proprietary network (like Infiniband interconnect), you can use another build of Charm++ like netlrts: ./build charm++ netlrts-linux-x86_64  --with-production. Additionally, if MPI is installed on the machine, you can also build Charm on top of MPI: ./build charm++ mpi-linux-x86_64 –with-production.

 

After building Charm++ successfully, the instructions in notes.txt should be sufficient to help you build NAMD.

 

Thanks,

Nitin

Building NAMD

In brief, the following steps are sufficient to build Namd and its dependent applications from the command line:

Part 1, FFTW: see building FFTW with a single change, use FFTW version(2.1.5)

Part 2, Charm++: see building Charm++

Part 3, NAMD: Now build the NAMD code.

Copy the file Linux-amd64-MPI-open64.archinto the arch subdirectory and then build NAMD.

Note: Linux-amd64-MPI-open64.archassumes that Charm++ was installed in $(HOME)/charm-5.9. If this is not the case, you need to modify CHARM_LOC in this file. The file Make.charm also needs to point to the directory where Charm++ is installed.

There is also an implicit assumption in the file arch/Linux-amd64.fftw that assumes FFTW was built in $(HOME)/fftw. If this is not true, you need to modify that file as well.

Now we continue as follows on command line:

     >cd ../namd_2.6

Then download the Linux-amd64-MPI-open64.arch file and copy to the archdirectory in namd_2.6. Also the Linux-amd64.fftw file should be copied to the same location,

     >./config fftw Linux-amd64-MPI-open64

     >cd Linux-amd64-MPI-open64

     >make

Known limitations

There is a bug in opencc such that if the serial C code in Charm++ is compiled with -O2 or higher, it will result in a hang during execution. The workaround is to use -O1 for CMK_SEQ_CC. This workaround is incorporated in the distributed conv-mach.sh, and seems to have no performance impact.

Can someone who've built NAMD before answer this question?

oh! sorry, I must have missed them.

I followed the following line of instructions:

tar xf NAMD_2.11_Source.tar.gz
cd NAMD_2.11_Source
tar xf charm-6.7.0.tar
wget http://www.ks.uiuc.edu/Research/namd/libraries/fftw-linux-x86_64.tar.gz
wget http://www.ks.uiuc.edu/Research/namd/libraries/tcl8.5.9-linux-x86_64.tar.gz
wget http://www.ks.uiuc.edu/Research/namd/libraries/tcl8.5.9-linux-x86_64-threaded.tar.gz
tar xzf fftw-linux-x86_64.tar.gz
mv linux-x86_64 fftw
tar xzf tcl*-linux-x86_64.tar.gz
tar xzf tcl*-linux-x86_64-threaded.tar.gz
mv tcl*-linux-x86_64 tcl
mv tcl*-linux-x86_64-threaded tcl-threaded
cd charm-6.7.0
./build charm++  verbs-linux-x86_64 gcc --with-production

In first try, they were showing some indiband/verbs.h missing; then when I corrected that, a string of other errors in various machine.c and related files

Hi Sutirtha,

Could you tell us what the build command was?
Also, the attachments seem to be missing.

Hello
I am having problems with building of charm++. Apparently, a file named "infiniband/verbs.h" is missing in the package due to which the build is not executed completely. Even if I make the program ignore that include statement, I'm getting a string of errors due to which the build is terminated. I am getting the errors, as given in the files attached error_1 and error_2 respectively. Please check the problems and look into it.I will be obliged.

Thanking You,
Sutirtha Kamal Sen
