Charm++ parallel programming system

[Phil Miller <mille121 AT illinois.edu>]

Hi Alberto,

Trying to build on one architecture (arm) with a configuration written to target another (x86[_64]) is unlikely to be helpful. If you want to try the newer netlrts network layer in place of the older net layer, I would suggest copying the contents of src/arch/net-linux-arm7 to src/arch/netlrts-linux-arm7, and then building against that:

cp -a src/arch/net-linux-arm7 src/arch/netlrts-linux-arm7

./build AMPI netlrts-linux-arm7 syncft -g -O0 -DCMK_USE_MEMPOOL_ISOMALLOC=1

You probably do *not* want to 'gcc' option, since that's really only geared for systems where the GNU compilers are not the default.

If the above builds and runs basic programs correctly, please let us know, so that we can incorporate that support. We don't have convenient arm-based test systems on which to qualify it.

Phil

Hello,
I am trying to build AMPI in a dual-core ARM processor running ArchLinux OS.
I have tried the net-linux-arm7 version but I get errors on migration and
haven't been able to solve them. This has encouraged me to try and build other
versions, which all gave errors probably due to using ArchLinux. The dual-core
ARMs are 32-bit, so I have tried building with:
'./build AMPI netlrts-linux syncft gcc -g -O0 -DCMK_USE_MEMPOOL_ISOMALLOC=1'
I used the compiler option 'gcc' as it gave me erros trying the option g++ -
m32, which didn't work probably because ArchLinux doesn't use g++. Even
though, I have a file linking g++ to gcc, but '-m32' seems to not be
recognized by gcc.
Using this type of build seemed to go correctly, but later on it gave the
following error:

Did you try to build net-linux on a 64-bit system? Try net-linux-x86_64

Suggesting to try a 64-bit version. The ARMs, as I mentioned before, are 32-
bit, so this shouldn't be the problem. Even though, and just to be sure, I
tried building with:
'./build AMPI netlrts-linux-x86_64 syncft gcc -g -O0 -
DCMK_USE_MEMPOOL_ISOMALLOC=1'
And, as expected, some errors came out as the binaries made were not 64-bit:

../bin/../include/conv-config.h:57:2: error: #error "Compiler not generating
64 bit binary, please check compiler flags."
 #error "Compiler not generating 64 bit binary, please check compiler flags."
