Hi Castain Does “install the autotools under VxWorks” mean install the autotools on the host or on the target ? Jing Zhang 发件人: devel-boun...@open-mpi.org [mailto:devel-boun...@open-mpi.org] 代表 Ralph Castain 发送时间: 2010年4月16日 11:36 收件人: Open MPI Developers 主题: Re: [OMPI devel] Migrate th

Ralph, If you are suggesting that you will make code that breaks a current rankfile feature, note I am not talking about adding a new feature that isn't supported by rankfile but something that used to work, then I think you are acting in poor form. At a minimum you should at least give the

To be clear, I wasn't implying anyone would intentionally break rank_file. However, it is rarely (if ever?) tested before we release - AFAIK, none of the MTT tests run by the community test this feature. Thus, it inevitably breaks without detection as changes are made elsewhere in the system. We

You would install it on the host where you are doing development. Only the eventual OMPI libraries get moved to the target. On Apr 16, 2010, at 12:11 AM, 张晶 wrote: > Hi Castain > > Does “install the autotools under VxWorks” mean install the autotools on the > host or on the target ? > > Jin

Re: [OMPI devel] problem when binding to socket on a single socket node

Well, I guess I got sucked back into paffinity again...sigh. I have committed a solution to this issue in r22984 and r22985. I have tested it against a range of scenarios, but hardly an exhaustive test. So please do stress it. The following comments are by no means intended as criticism, but ra

Forgot to mention this tip for debugging paffinity: There is a test module in the paffinity framework. The module has mca params that let you define the number of sockets/node (default: 4) and the #cores/socket (also default: 4). So by setting -mca paffinity test and adjusting those two paramet
