Hi *, I'm trying to get used with the binding option in the SGE.
Doing things like #$ -binding env linear:24 leads to allocated cores such as binding 1: ScttcttcttcttcttcttcttcttcttcttcttcttScttcttcttcttcttcttcttcttcttcttcttctt The $SGE_BINDING shows up with: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 That looks fine (to me). But whenever I use the striding strategy i.e.: #$ -binding env striding:7:3 I get the right pattern for the cores: ScttCTTCTTcttCTTCTTcttCTTCTTcttCTTCTTScttCTTCTTcttCTTCTTcttCTTCTTCTTCTTCTT But the entries in SGE_BINDING are: 0 12 24 36 There are always 4 numbers. According to loadcheck these could be the first cores of each socket: loadcheck Your SGE has core binding functionality (built with hwloc). Your kernel version is: 3.0.74-0.6.6-default Number of sockets: 2 Number of cores: 24 Number of threads: 48 Topology: SCTTCTTCTTCTTCTTCTTCTTCTTCTTCTTCTTCTTSCTTCTTCTTCTTCTTCTTCTTCTTCTTCTTCTTCTT Mapping of logical socket and core numbers to internal Internal processor ids for socket 0 core 0: 0 24 Internal processor ids for socket 0 core 1: 1 25 Internal processor ids for socket 0 core 2: 2 26 Internal processor ids for socket 0 core 3: 3 27 Internal processor ids for socket 0 core 4: 4 28 Internal processor ids for socket 0 core 5: 5 29 Internal processor ids for socket 0 core 6: 6 30 Internal processor ids for socket 0 core 7: 7 31 Internal processor ids for socket 0 core 8: 8 32 Internal processor ids for socket 0 core 9: 9 33 Internal processor ids for socket 0 core 10: 10 34 Internal processor ids for socket 0 core 11: 11 35 Internal processor ids for socket 1 core 0: 12 36 Internal processor ids for socket 1 core 1: 13 37 Internal processor ids for socket 1 core 2: 14 38 Internal processor ids for socket 1 core 3: 15 39 Internal processor ids for socket 1 core 4: 16 40 Internal processor ids for socket 1 core 5: 17 41 Internal processor ids for socket 1 core 6: 18 42 Internal processor ids for socket 1 core 7: 19 43 Internal processor ids for socket 1 core 8: 20 44 Internal processor ids for socket 1 core 9: 21 45 Internal processor ids for socket 1 core 10: 22 46 Internal processor ids for socket 1 core 11: 23 47 Is that correct?
