Monika, is there ant reason why you use openmpi 1.4.5 ? it is quite antique today, 1.10.2 is the latest stable version.
strictly speaking, openmpi does not require linux, it works fine on Solaris, bsd variants, Cygwin and other arch. the memory footprint is made of the library size, and the memory it allocates internally (buffers for communication for example) at first glance, I am not sure you should start focusing on the library size. I'd rather suggest you start with openmpi 1.10.2, and then try configure && make && make install if you are stuck, then please post the details so we are able to help Cheers, Gilles On Saturday, March 19, 2016, Monika Hemnani <hemnani...@rknec.edu> wrote: > I am building a multiprocessor system with soft-core processor(Microblaze) > and operating system xilkernel(OS from xilinx).
