....a conventional compiler, it just operates on the source code. The target architecture are Sun shared memory MIMD machines such as Enterprise Servers or multi processor SPARCstations running Solaris. The programs generated by the system can be directly linked with the Solaris thread library [Sun94] to produce code that runs in parallel. 2.3 Requirements A program to be handled by the system has to meet the requirements listed below. Chapter 3 gives background information regarding these restrictions and shows how to recognize, handle, and overcome them in your programs. Program the ....

....5.4 operating system. When using the threaded version of TSF on this server, a dramatic increase in performance has been achieved. This was only possible after understanding the Solaris thread model and related thread issues. The Solaris thread model consists of threads belonging to two categories [19]. User level threads. Termed unbound threads, they operate within user space without consuming any kernel resources. The user thread is lightweight, and the operation of creating such a thread is 30 times less expensive than executing a new process. Kernel level threads. Termed bound ....

....our emphasis on timing fault management to prompt recovery and adaptation of the computation. 3 The real time library The rt lib real time library is built on top of Solaris 2. 6, a general purpose operating system of the UNIX family offering partial support to soft real time computation [17]. Of course, Solaris is not a fully real time operating system, and hence it would not be able to manage hard real time applications with tight requirements. A key requirement for structuring control architectures for autonomous robots is the availability of effective abstractions for ....

....and ray tracing. We show that Hood delivers efficient performance under multiprogramming. For all the applications, we observe linear speedup whenever the number of processes is small relative to the average parallelism. Our implementation of Hood is built on top of the Solaris thread library [47], and it implements each process as a Solaris Light Weight Process (LWP) It also uses the atomic casxa [46] 64 bit compare and swap instruction of the SPARC v9 architecture) to implement a non blocking version of the work stealing algorithm. All experiments were performed on a Sun Ultra ....

....by binding the thread to an LWP. Binding the time shared thread (TST) to the LWP, ties them together such that whenever the LWP runs, the TST runs, and no other TST may be scheduled to run on that LWP. It was then possible to use the underlying LWP to have the thread scheduled by the kernel. Sunc] The RTTP RTThread had to use the Solaris thread types because there is no other convenient way to create user level threads. Although the BTP is a portable C framework, the internals of the BTP Thread class had to be modified (Figure 1) to get real time threads to work. A design goal of the ....
