Dear Gadget list,
I met a problem using Gadget2 on our beowulf cluster at the Geneva
Observatory.
The use of the command system(buf3); (begrun.c, line +-652) causes MPI
to block.
Thus, I suggest to replace the lines :
sprintf(buf1, "%s%s", fname, "-usedvalues");
sprintf(buf2, "%s%s", All.OutputDir, "parameters-usedvalues");
sprintf(buf3, "cp %s %s", buf1, buf2);
system(buf3);
by :
/* copy parameters-usedvalues file*/
sprintf(buf1, "%s%s", fname, "-usedvalues");
sprintf(buf2, "%s%s", All.OutputDir, "parameters-usedvalues");
fd = fopen(buf1,"r");
fdout = fopen(buf2,"w");
while(1)
{
fgets(buf, 200, fd);
if (feof(fd)) break;
fprintf(fdout, buf, 200);
}
fclose(fd);
fclose(fdout);
This problem seems to be system dependent.
A similar system call is present in restart.c and should be replaced.
Cheers.
