Re: [OMPI devel] Which tests for larger cluster testing
Cisco is not yet testing that large, but we plan to shortly start testing at np>=128 (I'm waiting for an internal cluster within Cisco to be setup properly).

(Although I realize that is not very large, but it is bigger than most of the clusters I assume tests are being run on) I ask this because I planned on using some of the intel tests, but they clearly have limitations starting at np=64. To avoid mailing list clutter, feel free to just email me and I will summarize.

Re: [OMPI devel] Which tests for larger cluster testing
Hi; I am not sure this is relavent to your question. I do have an computational fluid dynamics application which solves fluid flow problems. Recently I was able to run this code up to 2048 processors on the Indiana University's IBM e1350 BigRed cluster. I did use 1.2.3 version of the OpenMPI. I am happy about the preformance I did get. (I am using point-to-point sendrecv in this code).

[OMPI devel] Adding a new component to MTL
hello, I am a newbie to OpenMPI and started digging into code base. I am trying to add a new component to MTL(mca/mtl/). I assumed adding a new component to MTL, is no different than adding a component to BTL and followed slides below to do so. http://www.open-mpi.org/papers/workshop-2006/mon_07_mca_part_2.pdf Also, defined mca_mycomponent_init(bool enable_progress_threads, bool enable_mpi_threads), as mentioned in ( http://www.open-mpi.org/community/lists/devel/2007/09/2294.php ), which for now only returns success. Then ... $ompi-trunk/autogen.sh $ompi-trunk/configure --prefix= seems to generate relavant make file. However, $ make all install doesn't compile my component. Is there something I am missing ? Any ideas or documentation I should be reading. thanks in advance, -Manjunath
