Thierry Guest Posts: n/a	Hi ! I want to run Fluent 6.3.26 on our computer (SUN X4600, 8 * AMD opteron Dual core 64bit <=> 16 computational nodes) which is not a cluster. The OS is Linux64 and the file batch is SGE. The problem is that when you submit more than one parallel job at the same time, the jobs use always the same fist processors !! Ex : if I submit 2 jobs on 8 procs, only 8 procs are used with 50% and the other 8 procs are free !!! I heard that it is a bug of Fluent 6.3.... Is someone knows how to fix this problem ? Thank you. Ps : this bug seems to be fixed on 6.4.11 version...but it's a beta version...
