    Digital Design Using VHDL: A Systems Approach. performed the Department of Energy LLL loops at roughly the speed of the CRAY The BSP combined parallelism and pipelining, performing memory. CRAY Super Computer. The first Cray-1™ system was installed at Los Alamos National Laboratory in for $ million. At this time it's 10 times faster than the biggest IBM, with six times more memory. It boasted a world-record speed of million floating-point operations per second ( megaflops) and an 8 megabyte (1 million word) main.

    Most non-government Cray-1 systems were front-ended by CDC CYBER systems, IBM MVS or VM machines or DEC VAX systems. Apart from the first Cray-1, which travelled the world, the first machine of most product types typically served in the Cray computer centre (CCN) first at Mendota Heights and later at Lone Oak Road, Eagan. Much of the cruft results from C++'s attempt to be backward compatible with C. Stroustrup himself has said in his retrospective book "The Design and Evolution of C++" (p. ), "Within C++, there is a much smaller and cleaner language struggling to get out." [Many hackers would now .

    The second book kind of expanded, and is now "The Traders War" and "The Revolution Trade". The entire "Empire Games" trilogy corresponds to book 3 of the original plan, but no plan ever survives contact with the enemy, let alone years of wall-clock time and the march of history. To recap: we live in a multiverse.
