Charm++ parallel programming system

["ion.mironescu" <ion.mironescu AT ulbsibiu.ro>]

Hello,

I use charm 6.2.0 downloaded from the web site on a QS22 blade with Linux

Building environment: 

gcc  using built-in specs.
Target: ppc64-redhat-linux
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-libgcj-multifile --enable-languages=c,c++,objc,obj-c++,java,fortran --enable-java-awt=gtk --disable-dssi --enable-plugin --with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre --enable-secureplt --with-long-double-128 --host=ppc64-redhat-linux --build=ppc64-redhat-linux --target=ppc64-redhat-linux --with-cpu=default32
Thread model: posix
gcc version 4.1.2 20080704 (Red Hat 4.1.2-44) 

Linux version 2.6.18-128.7.1.el5

Cell Sdk 3.1

i need help in two issues (possibly corelated).

1)  the first try to build the charm++  core failed signaling an error in simd.h at line 689

 inline veclf vinsertlf(veclf v, const double s, const int i) { return vec_insert(s,v,i); }

invalid parameter for Altivec intrinsic

i replaced that line with

    inline veclf vinsertlf(veclf v, const double s, const int i) { veclf r = v;  double* rPtr = ( double*)(&r); rPtr[i] = s; return r; }

and the build ended wit the succes message

Is my replacement correct and safe?

2) when i try to compile anyting from the test or examples directories i received this error messages

./../../bin/charmc  -language charm++ -o hello hello.o -lm

   Command spu-gcc -Wl,-N -L../../../bin/../lib -o main__funcLookup__.genSPECode main__funcLookup__.genSPECode.o -lcellspu returned error code 1
charmc exiting...

Normaly sqrt should be defined in math.h wich is not anymore included  for Cell in the same simd.h  ( where  the offending function _vsqrt is also defined)

I tried to include math.h and  to link with the math library (-lm)  but nothing works.

It seems to be more a link as an include probleme but i don't have a clue.

Please help me in this second issue!

Thank you!

With best regards

Ion Mironescu
