[Librsb-users] librsb on FreeBSD

[Montgomery-Smith, S. <st...@mi...>]

I just got an email from Michele Martone invting me to this mailing
list.  I wrote some FreeBSD ports:
 https://www.freshports.org/math/librsb/
 https://www.freshports.org/math/octave-forge-sparsersb/

The main issue I have with installing librsb on FreeBSD is setting the
variable RSB_USER_SET_MEM_HIERARCHY_INFO.  I have a rather cryptic
message to the port builder that says:

This port needs information about the memory cache system before
building.  You can set this in the variable
RSB_USER_SET_MEM_HIERARCHY_INFO, for example make
RSB_USER_SET_MEM_HIERARCHY_INFO="L2:12/64/3M,L1:64/8/32K"
Finding these values is tricky, but the following steps will help:
        1. read the README file in the source code
        2. build the port misc/cpuid
        3. run the program cpuid
You are on your own in figuring out how to convert the information from
the program cpuid to the value of RSB_USER_SET_MEM_HIERARCHY_INFO.


I found it quite hard to convert the info from the program cpuid to some
reasonable cache values.  This was quite a while ago, but I think it
involved a lot of using google.

If anyone is interested in making this process more automated, I'll
happily send you a sample output from cpuid, and any other help I can
provide.

Thanks, Stephen
