Jonathan:
BOINC doesn't limit the # of CPUs as far as I know.
On Linux, the client gets the # of CPUs using:
p_ncpus = sysconf(_SC_NPROCESSORS_ONLN);
Can you see what this returns on your system?
i.e. run a program of the form
#include <stdio.h>
#include <unistd.h>
int main() {
printf("%d\n", sysconf(_SC_NPROCESSORS_ONLN));
}
If it shows 128, try replacing _SC_NPROCESSORS_ONLN with _SC_NPROCESSORS_CONF
and see what it says.
