這幾天，在HPC上安裝調試Linux版的STAR-CCM+ 11.06.010-R8, 以串行模式加載算例時，能夠成功計算。但是以並行方式加載算例時，會報出一大堆錯誤信息：

緊緊圍繞着“”multiple pkey found in partition key table, please choose one via MPI_IB_PKEY“”這句話，通過"http://guge.firstguo.com/"一路來到Mellanox的社區論壇：
https://community.mellanox.com/docs/DOC-2232
裏面有這麼一句話：For example, the default PKEY will either have a value of 0x7FFF (limited) or 0xFFFF (full).
果斷地在用戶環境變量文件.bashrc中添加環境變量：export MPI_IB_PKEY=0x7FFF
再次啓動starccm+, 以並行方式加載算例，成功加載，然後順利開始並行計算！！
