Charm++ parallel programming system

[Christiane Pousa <pousa.christiane AT gmail.com>]

Charm version: charm-6.1.3 and the command was: ./charmrun  kNeighbor 15 10 1024 +p16

To better explain what I have done :
First I tried to install just smp version on a NUMA machine (AMD opteron with 16 cores). But, this resulted in the error I sent in the last email.  The option 
net-linux-x86_64-smp seems not to work in AMD64.

After that, I tried net-linux-amd64-smp version and works well if I execute the program with this coommand:
./charmrun ++local kNeighbor 15 10 1024 +p16

If I remove '++local' I get this error: ssh_exchange_identification: Connection closed by remote host

Thank you,

Which charm version did you use, and what's the exact command do you use to execute the program?

 

According to our auto-build status, the net-linux-x86_64-smp (http://charm.cs.uiuc.edu/autobuild/cur/)  works fine.

Hi,

I have installed charm++ SMP version, but when I run some examples (kNeighbor, jacobi) I have got the message:
Signal: segmentation violation
Suggestion: Try running with '++debug', or linking with '-memory paranoid'.

In same examples with charm++ net-linux-amd64 installation, I have not get these errors. Would you know why SMP instalation does not work on NUMA machines?

Thank you,

Does your machine have multiple multicore-based nodes? If not, you could install the multicore version of charm++, otherwise, a SMP version is usually a better choice.

Hi,

I have a multicore AMD Opteron machine with NUMA characteristics. I would like to know which option should I use to install charm on this machine,  multicore(single node only), SMP or net-linux-amd64?

Thanks,
