The files "ecdl" and "ecdl-sol7" are binary executables for UltraSPARC ported and compiled by Laurent Desnogues. The first one, "ecdl" requires an UltraSPARC ("uname -r" should answer "sun4u"). It is quite big at 398 K but there is a compressed 95 K version in "ecdl.gz". Note that it is much faster than the one that was here this morning (September 2nd). It runs at about 178 k iterations per second on a 333 MHz UltraSPARC-IIi. The second one, "ecdl-sol7" runs at 200 k iters/sec on the same chip but it requires an UltraSPARC with Solaris 7 a.k.a. SunOS 5.7. ("uname -r -m" should answer "5.7 sun4u"). Download, gunzip if necessary, do "chmod u+x ecdl" and run with arguments like this: ecdl { } : Either test, mail, alt or batch. : Something to identify you by e.g., your email address. : Name of the team you are on e.g., one you just made up! : The machine name. : The machine hardware type e.g, '333 MHz UltraSPARC-IIi'. : The OS name e.g., Solaris. : Optional extra text. Please see sections 3 and 4 of the readMe in source/64-bit/ for more detailed info. Rob.
