In my opinion it would be a violation of the granted slot count when you get more cores granted than slots. How should SGE deal with it for the jobs which are lateron scheduled to such a machine: still 4 slots free, but all 8 cores already used up - what to do?!? Hence the amount should be interpreted as a "reserve up to amount cores per machine", limited by the granted slot count per machine. So "-binding linear:4" would mean give me up to 4 cores per maschine if possible. - possibly only 3, when only 3 slots are granted on a machine - you will never ever get more than 4 slots per machine, i.e. it's an upper limit for slots per machine for this particular job -- Reuti > > --td > >> -- Reuti >> >> >> >>> to it (ie in case one exec6 only has 1 core and case 2 it has two where >>> maybe you'd expect 2 and 4 cores allocated respectively)? >>> >>> -- >>> <Mail-Anhang.gif> >>> Terry D.
