Parallel Implementation

of some characteristics of softwares for parallel computer algebra. SBSH means Sugarbush. PCLBSTM means PACLIB/STURM and PCGVR PAC/GIVARO. Conclusions. Major problems that appears in the design and implementation of parallel computer algebra systems (on-line scheduling of tasks, distributed garbage collection) are studied in the more general context of modern parallel programming languages. Also, parallel computer algebra focus nowdays on two directions. First, a development effort has to be done to integrate a modern parallel language in a general purpose computer algebra system with its huge libraries of complex algorithms. Second, active research should be done in the design of efficient and portable parallel algorithms for more complex problems.
