Hello,
I'm trying to get hwloc working on a Power6, AIX machine. compilation goes
well and the lstopo program works fine. However the hwloc-hello.c program
return an error when trying to bind a thread. This happens with hwloc
version 1.0, version 1.1a1r2215 and version 1.1a1r2219M.
Here's the last few lines from the hwloc-hello output (I just removed the
messages related to the system topology):
*** The number of sockets is unknown
*** Logical processor 0 has 1 caches totaling 0KB
Couldn't bind to cpuset 0xc0000000,0x0
--> Error 0
The last line prints the output of strerror(errno).
Details of my machine:
