What about hwloc_topology check()? What types of check does? 2011/9/3 Brice Goglin > > There's no way to implement this check safely (being non NULL doesn't mean > it was properly initialized by the user, it could still point to random > memory that would cause a

[hwloc-users] Re : Re : hwloc topology check initializing

There's no way to implement this check safely (being non NULL doesn't mean it was properly initialized by the user, it could still point to random memory that would cause a segfault when checking). If you really need something like this, put an integer value on the side of the topology

Re: [hwloc-users] Re : hwloc topology check initializing

Hi Brice, but it works only if the user assing NULL to topology. hwloc_topology_init() does not check the argument passed ? There are no ways to check if topology is initialized or not? Thanks. 2011/9/3 Brice Goglin > > Assign NULL to the topology when declaring the

Re: [OMPI users] High CPU usage with yield_when_idle =1 on CFS

I have already implemented test/sleep code but the main problem is with the broadcasts that send out the SIMD instructions, because these are blocking and when the system is idle, its these guys who consume the CPU while waiting for work. Implementing   echo "1" >
