There are two parts in the distribution: the first one contains all the data needed to perform the computations (Weber polynomials, etc.) and the second depends on the architecture you want ECPP to run on. Each tar file was compressed using gzip.
Once you have ftp-ed all the files, use gzip -d to uncompress them. This will create the directory Ecpp among others. Go into that directory and read the file README.ecpp to learn how to finish the installation.
For convenience (that is smaller files are easier to get than larger ones), the data part has been divided into five parts.
Here they are:ECPPDATA To give an example, on your machine toto, once you have ftp-ed the file ecppweber1.tar.gz, you have to type:
toto% gzip -d ecppweber1.tar.gz toto% tar xvf ecppweber1.tar
Now, to get the binaries, select one of:ECPPBINARIES
Important remarks: all the binaries are for Un*x-like operating systems. As time goes by, more binaries will flow in, depending on my taking time to do so.

H. Lehmer, J. L. Selfridge, Bryant Tuckerman and S. S. Wagstaff, Jr., vol 22 of AMS Contemporary Mathematics series), which are regularily updated. It is the first non trivial number whose primality I proved in 1987. ECPPBENCHMARKS Timings are in second. The benchmarks are given as is. In particular, this does imply any judgment of mine, or of my Laboratory.
