At this time, libpeak supports x86, m68k, powerpc (PowerPC 32/64 |
| 4 |
|
|
bits and POWER), sparc and IA-64 processors. |

List of platforms where libpeak is known to have compiled and passed |

Please note that libpeak should be particularly efficient on: |
| 31 |
|
|
|
| 32 |
|
|
Darwin 7.0+ (Mac OS X 10.3+) |
| 33 |
|
|
- kqueue engine |
| 34 |
|
|
- mach semaphores and good multi-threading support |
| 35 |
|
|
|
| 36 |
|
|
FreeBSD 4.9, 5.1+ |
| 37 |
|
|
- kqueue engine |
| 38 |
|
|
- good multi-threading support |
| 39 |
|
|
|
| 40 |
|
|
Linux 2.6+ |
| 41 |
|
|
- epoll engine (be careful to have a recent glib) |
| 42 |
|
|
- good multi-threading support only with a few threads, which is OK |
| 43 |
|
|
for libpeak |
| 44 |
|
|
|
| 45 |
|
|
The epoll engine is probably as good as kqueue except maybe for safe |
| 46 |
|
|
signals handling. Current epoll implementation in libpeak behaves as |
| 47 |
|
|
Level Triggered, but I plan to write later an Egde Triggered version |
| 48 |
|
|
to compare them. Other comparative stats should be available online on |
| 49 |
|
|
PEAK's web site one of these days. |

Performance with Solaris |
| 52 |
|
|
------------------------ |
| 53 |
|
|
If you're using Solaris 8 or more, you should use the alternate LWP |
| 54 |
|
|
threads library implementation (one-level model), which should be more |
| 55 |
|
|
efficient with libpeak than the default two-level threads model. The |
| 56 |
|
|
configure script doesn't enable them automatically for now, but you |
| 57 |
|
|
can enable them easily by setting: |
| 58 |
|
|
|
| 59 |
|
|
export LD_LIBRARY_PATH=/usr/lib/lwp |
| 60 |
|
|
|
| 61 |
|
|
before launching the program that uses libpeak (see man pthreads). |
