Who used infiniband in linux?

Who used infiniband in linux? -- Linux Enterprise Application-Linux server application information. For details, refer to the following section. Currently, the computing center I am using is redhat ws3.0 LINUX and is equipped with 10 Gb infiniband, however, it is depressing that no one has been using infiniband for a long time, leading to the current failure of infiniband Technology.

Due to the need for Quantum Chemistry computing, a large amount of parallel computing resources are required. The delay of TCP/IP protocol makes almost all parallel computing crazy. So I plan to use infiniband. I checked some preliminary information, as if infiniband needs a software named OFED to be correctly configured, and then compiled openmpi (or MVAPICH2, but the program developer said that OPENMPI is good, just trust it once) add '-- with-openib = ', Dir is the OFED directory. However, it is very depressing to find that the current operating system seems a little outdated as redhat ws3.0, and most OFED does not support

Has infiniband been used in the Help forum to help me? Is there any information for me?

By the way, is it feasible to update the gcc compiler for the redhat ws3.0 system? What is the maximum update value? It seems that some people say that updating gcc requires the support of the Linux kernel, and the old kernel update cannot reach the new gcc.

Very depressed, hope experienced experts to help (5ty (: 0w223dc

I don't know if the installation process of infiniban is correct. Please kindly advise me if you are knowledgeable.
