Heterogeneous computing system comprising a switch/network adapter port interface utilizing load-reduced dual in-line memory modules (lr-dimms) incorporating isolation memory buffers

A computer system comprising:

• at least one dense logic device;
• at least one controller for coupling said at least one dense logic device to a control bus and one or more memory buses;
• a plurality of memory slots coupled to said memory bus;
• one or more adaptor ports associated with at least one of said plurality of memory slots coupled to said one or more memory buses, each of said adapter ports including associated memory resources;
• and
• a direct execution logic element coupled to at least one of said adapter ports, said memory resources being selectively accessible by said at least one dense logic device and said direct execution logic element.

A computer system comprising:

• at least one dense logic device;
• at least one controller for coupling said at least one dense logic device to a control bus and a memory bus supporting a single rank of memory;
• an isolation memory buffer coupled to said memory bus;
• a plurality of other memory buses connected to said isolation buffer;
• one or more adaptor ports associated with at least one of said plurality of other memory buses, each of said adapter ports including associated memory resources;
• and
• a direct execution logic element coupled to at least one of said adapter ports, said memory resources being selectively accessible by said at least one dense logic device and said direct execution logic element.
