IRIX is also (see previous questions) a good system. You should not try replacing IRIX with Linux unless you are a really keen experimenter. Linux support for the SGI is not as good as for the SUN. Do however download all the GNU utilities you can get your hands on. SGI's are even better machines once given the GNU touch. Its worth mentioning that Silicon Graphics has actually pledged tremendous support to Linux. Silicon Graphics Intel based workstation are being shipped that run only Linux.

AIX®: It is displayed by the command - /usr/sbin/uname -m (then remove the last two digits and use the remaining last eight digits; e.g. 0007c29ac400 = 07c29a4c) Linux® (SGI® Altix® / Silicon Graphics Prism®): When available, it is displayed by the command - lmhostid. It can also be displayed by the command cat /proc/sgi_sn/licenseID (remove the 0x prefix from the returned value. e.g. 0x201e8634 = 201e8634). See similar questions...

The 1.1 release will be out "soon" as part of IRIX 6.5; this release has some minor improvements and bug fixes over version 1.0.2 (which is currently shipping). We don't have any concrete information yet on the status of Cosmo Player 2.x for IRIX. We've also gotten lots of requests for a Linux player; there are no plans for this in the immediate future, but it may become more of a possibility as we get closer to releasing the IRIX version.

If you are using a 64-bit OS, you need to add the -o32' option for the compiler, or use gcc. With the SGI compiler, you may also need to play with optimization. Some modules may have exhibit problems unless compiled with -O1' or even '-O0'. Script-Fu requires the POSIX-compliant regex functions, which SGI only supports with IRIX 6.2 and later versions. The GNU version of regex should work just fine, though, and is available at: See similar questions...

In short, Linux is a free, powerful, and stable operating system like Windows98, except Linux is free, powerful and stable. See similar questions...

There are numerous patches designed to provide access to the Intel CPU performance counters. As PAPI began, we used the original Beowulf patch (perf) by David Hendriks. However, as PAPI progressed, we needed some addition features, which I graciously added. This patch used a system call approach and has proven to be exceedingly stable. Yes, no crashes reported.

No. AAA Version 1.7 was the last version of AAA that ran on UNIX workstations. There are no plans to port AAA back to the workstations. AAA runs under Windows on PC and under window emulators on workstations such as SoftWindows or VirtualPC. See similar questions...

Copy your licence file (isl_license.dat) into /usr/ISL/FLEXlm/. The licence file will have been sent to you as an email attachment. The server will start automatically at system startup, this can be controlled using the chkconfig system command. FLEXlm messages are logged to /var/sysadm/isllmgrd/isllmgrd.log. The init script accepts the usual start and stop commands, and also restart, status (which runs lmstat) and reread, which rereads the licence file. See similar questions...

REACT is the set of real-time features that comes standard with every IRIX installation (asynchronous i/o, schedctl, plock, itimers, nanosleep, etc). REACT is not an optional product but an integral part of IRIX. Many of the REACT extensions to IRIX benefit non-traditional, real-time applications such as multimedia and graphics. With multiprocessor systems, REACT also includes features such as processor control and isolation, multiprocessing control, and interrupt routing. See similar questions...

With IRIX 6.5, there are two models for achieving real-time determinism: the processor isolation model and the kernel preemption model. Briefly, here are the definitions for these two models: This model achieves determinism by executing real-time processes at high priority and relying upon preemption, including preemption of kernel processes and interrupts, to ensure that the highest priority runable process always is executing. This model is a superset of the kernel preemption model. See similar questions...

There are ubiquitous context switch benchmarks available that demonstrate a wide variety of results over a wide variety of constraints, conditions and CPU speeds. One benchmark, for which code can be provided, produces the following results for context switches between two processes (NOT threads) on an Origin 2000 system running on an isolated 180MHz MIPS R10000 CPU under IRIX 6.5.10f: Please note that the numbers above are an example of the performance.
