What is 't2'

't2' is a Sun T5240 with 2 processors, 16 cores, and 128 threads. The T5240 is capable of blistering performance as a web server, but its architecture is poorly suited for Sage, so building Sage takes quite a bit of time. The speed to build is compounded by the fact that ATLAS has no tuning parameters for the sun4v architecture, so has to determine them each time.

What versions of Sage build on 't2'

The latest Sage to build on 't2' is 4.3.0.1. Something got broke in 4.3.1, so it will not build.

How do I build Sage on 't2' ?

You need to get your path set correctly, as well as LD_LIBRARY_PATH. You also need to have GNU versions of 'tar' and 'make', rather than use the Sun ones.

The following should allow you to build Sage on 't2'. Everything will be set up for you then.

$ export PATH=/usr/local/gcc-4.4.1-sun-linker/bin:/usr/local/bin2:/usr/bin:/usr/ccs/bin:/usr/local/bin:/usr/sfw/bin:/bin:/usr/sbin
$ export LD_LIBRARY_PATH=/usr/local/gcc-4.4.1-sun-linker/lib:/usr/local/lib
$ tar xf sage-4.3.0.1.tar
$ cd sage-4.3.0.1
$ make
$ ./sage
