Charm++ parallel programming system

[Phil Miller <mille121 AT illinois.edu>]

Again, given a 4 year old compiler, my primary instruction would be to use a newer compiler.

If you post the error message you received, we may be able to help, though. If it's actually an error in compiling NAMD, we'll refer you to the NAMD mailing list.

Dear Mr.Miller,

Thank you so much for your instruction.
I also want to deal with some newer CentOS, but it's impossible now.
I also tried to build namd with Intel compiler 2013, I success to build Charm++, but have trouble on building Namd step.
I don't have experience to deal with error compiling something on Linux.
Do you have any document which guide one to build Namd with Intel compiler and OpenMPI?
Can with share it to me?

Thank you so much for your help.

Charm++ 6.7.1 requires a compiler at least as capable as g++ version 4.4 for the partial C++11 support it provides. This was released many years ago, and was incorporated in Linux operating system distributions shortly thereafter.

CentOS version 5.8 was released over 5 years ago, and with its official End-of-Life, it ceased receiving even the most critical updates earlier this year. I recommend installing a more modern operating system version.

If that's not feasible, you could install a newer compiler version and use that to build Charm++ and NAMD. As an added bonus, you'll get better performance from improved optimizations.

Dear Developers, 

I try to compile NAMD 2.12 on a cluster (Centos 5.8)

​I am not familiar with such kind of situation.​

​I wish you could give me some advise to solve this.

I am looking for your advise​.
