I am running Ubuntu 14.04 and am having various issues with libimf.so (see my questions on Ask Ubuntu: 1, 2). While waiting to sort those issues out, I am trying to figure out what libimf.so is actually for. Googling libimf.so is not helpful, so can anyone tell me what the libimfo.so shared library is for? My Ubuntu cannot find this shared library anywhere else except under the Intel compiler distribution under /opt. 
What is the purpose of libimf.so?
libraries;shared library;intel graphics
It is the Intel Math Library. It contains optimized versions of functions such as sin, pow, etc typically found in libm. It is needed by software built with the intel compiler unless steps were taken to link it statically.
