i386 (2xPIII800, 1xAMD 850), Linux (RH 6.2), PVM 3.4.3

No. Tried it, but it is slower than at one procesor without PVM :(.

During parsing. When renderings starts, pvmd falls down to reasonable size (under 1MB)

Render ends correctly. Loads are

           host name  [ done ] [ late ]           host name  [ done ] [ late ]
Infinity.localdomain  [11.69%] [ 0.37%]Infinity.localdomain  [ 8.62%] [ 0.00%]
               linux  [79.69%] [ 0.00%]


(Infinity is 2xPIII800, linux is 1xAMD 850, I think, that AMD is much faster for
render, this has influence of loads)
