Re: [OMPI devel] SOS... help needed :(

Hi, Some of our clusters uses Gigabit Ethernet and Infiniband. So we are trying to multiplex them. Thanks and Regards Pooja > On Thu, Apr 19, 2007 at 06:58:37PM -0400, po...@cc.gatech.edu wrote: > >> I am Pooja working with chaitali on this project. >> The idea behind this

Re: [OMPI devel] SOS... help needed :(

Hi, I am Pooja working with chaitali on this project. The idea behind this is while running a parallelized code ,if a huge chunks of serial computation is encountered at that time underlying network infrastructure can be used for some other data transfer. This increases the network utilization

Re: [OMPI devel] SOS... help needed :(

Hi!!! I am Pooja ,I am working with chaitali on this project. What we meant by Btl_Tcp is a call to btl_send that our program will give directly on the higher levels.In short we want to call BTL transport at the higher levels and so we have configure openmpi using all development header files

Re: [OMPI devel] SOS... help needed :(

network calling BTL btl_send function directly . Another option is not to use BTL_send but to send using TCp socket (writing our own tcp_send code). SO we just want to ask whether that is possible and if yes what we are thinking ahead is right?? Thanks a lot Pooja > On Sun, Apr 15, 2007

Re: [OMPI devel] Is it possible to get BTL transport work directly with MPI level

Hi!! Thanks for reply.Actaully there was some problem with the my downloaded version of openmpi.But when I downloaded everything again and did all configure and make statements again it worked fine. Thanks a lot . And next time I will make sure that I give all details. Thanks Pooja > This

Re: [OMPI devel] Is it possible to get BTL transport work directly with MPI level

Hi!!! Thanks for help!!! Right now I am just trying to install the normal openmpi(without using all development header files). But it is still giving me some error. I have downloaded the developer version from the openmpi.org site. Then I gave ./configure --prefix=/net/hc293/pooja/dev_openmpi

Re: [OMPI devel] Is it possible to get BTL transport work directly with MPI level

reason I was asking to know the state changes or atleast the way to find it out. Also my proff asked me to look into BTl transport layer to be used with MPi Api. I hope you will help. Thanks and Regards Pooja > On Apr 1, 2007, at 3:12 PM, Ralph Castain wrote: > >> I can't

Hi I am Pooja and I am working on a course project which requires me -> to track the internal state changes of MPI and need me to figure out how does ORTE maps MPi Process to actual physical processes ->Also I need to find way to get BTL transports work directly with MPI level calls. I jus

[OMPI devel] Hi!! need to find internal state changes

Hi everyone. I am Pooja and I am doing a project in my High performance computing lab. In this project I need to find the internal state chnages of Openmpi.For eg:When does MPi_send is used how does messages are actually send and how does control messages are send. Please help me. Thanks and
