Monitoring in a software development environment

Richard Snodgrass
1984 SIGPLAN notices  
The information collected and processed by a monitor is vital for debugging and tuning programs, and is useful to compilers performing selective optimization.  ...  Measurements of an initial implementation of the relational monitor show that it can efficiently support the conceptual viewpoint of a dynamic database of a program's behavior.  ...  Applying update network optimizations and using an update network compiler results in a processing rate of over 600 data records per second on a dedicated Vax 11/780.  ...

Design Trade-Offs in VAX-11 Translation Buffer Organization

M. Satyanarayanan, D. Bhandarkar
1981 Computer  
Consequently, the extension ofvirtual address space was a primary goal of VAX architects.  ...  One of the major architectural limitations of the PDP-I I has been its small virtual address space.  ...  A more detailed account of how the hardware and software treat trace traps is found in the VAX-11/780 Architecture Handbook.4 The user-written condition-handling routine is linked to the program to be  ...

RISC I

David A. Patterson, Carlo H. Sequin
1998 25 years of the international symposia on Computer architecture (selected papers) - ISCA '98  
Preliminary benchmarks demonstrate the performance advantages of RISC. It appears possible to build a single chip computer faster than VAX 11/780.  ...  Although instructions are simpler, the average length of programs was found not to exceed programs for DEC VAX 11 by more than a factor of 2.  ...  The RISC Project has been sustained by a large number of students. We would like to thank all those in the Berkeley community who have helped to push RISC from a concept to an engineering experiment.  ...
