Common use of Throughput Requirements Clause in Contracts

Throughput Requirements. The time to process a job is a function of a number of parameters including whether background of foreground printing is used, complexity of the print job (print quality, number of passes, color settings), load on the network, the CPU (internal HD, amount of RAM, processor), and I/O channel. Three fundamental time metrics are to be used in measuring performance: o Return to application (RTA) o Click to Start printing o Printing o Click to Clunk (just add click to start and printing times). Return to Application (RTA) for Basic and WorkGroup RTA is defined here as the time from starting the printing process (click) to when the host is ready to continue normal working with application (no noticeable performance degradation due to printing process). The generic goal for RTA time equals 10% of the total printing time (click to start plus printing time). This will apply to Eiffel plot suite provided by HP. HP understands that actual RTA time highly depends on specific plot and RIPping computer performance, so a plot suite with specific RTA times defined for each plot will be provided by HP. Reduced RTA is one of the main differentiators of the WG Solution versus the Basic one. This is achieved thanks to the server based architecture where the ripping of the print if performed OEM SOFTWARE DEVELOPMENT AND LICENSE AGREEMENT No 12/00 on the server and so the client workstation is not loaded. This is because in terms of RTA shall be defined two different goals, one for the typical configuration where the client is running on a different workstation than the server, and another where client is running on the same workstation as the server. RTA: client on different workstation than server Under this configuration the Ripping is not done on the client workstation. The WG solution shall provide a RTA for the client which is equivalent to the RTA there would be if instead of a SW RIP, an embedded PS printer was connected to the client. The goal for Eiffel is to obtain same RTA values as DesignJet 1055 when using the PostScript driver (running on same workstation). ICD will provide target numbers for the different plots included in the Eiffel plot suite. RTA: client on same workstation than server

Reduced RTA is one of the main differentiators differences of the WG Solution versus HP SW RIP solution when the Basic one. This RIP is achieved thanks running in the same workstation than the graphics application, compared to the server based architecture where separated scenario (client/server): in the case of 2 different workstations (client and server) the ripping of the print job if performed OEM SOFTWARE DEVELOPMENT AND LICENSE AGREEMENT No 12/00 on the server and so the client workstation is not heavy loaded. This is because in terms of So, RTA goals shall be defined two different goals, one for both: the typical configuration where the client is running on a different workstation than the server, and another where client the standalone ones. Click to Start printing This is running the time since the starting of the printing process (i.e., the users clicks on "print" in the same workstation as application) to the servermoment the printer effectively starts to print. Same requirements than RTA: client on different workstation than server Under this configuration . Mechanical printing time Once the Ripping is not done on RIP starts sending rendered data to the client workstationprinter device engine, a minimum-rendering throughput shall be guaranteed in order to avoid printing stopping in between swaths (which can produce image quality problems). HP will provide additional information with the required rendering throughput (Kbytes/s) for each particular media/print quality combination. The WG solution compression algorithm to be applied to the generated raster data shall provide be the method number 2 as described in the PCL Implementers guide (TIFF Pack bits Encoding). HP is responsible for defining a RTA table of resolutions/print times that meets I/O bandwidth as well as detailed throughput goals for the client which is equivalent to the RTA there would be if instead of a SW RIP, an embedded PS printer was connected to the client. The goal for Eiffel is to obtain same RTA values as DesignJet 1055 when using the PostScript driver (running on same workstation). ICD will provide target numbers for the different plots included in the Eiffel plot suite. RTA: client on same workstation than serverThe contractor is responsible for providing a SW RIP that can provide defined rendering speeds for the plots included in the Eiffel plot suite. A requirement that must be clearly stated (for PQ reasons) is that the printer must not stop printing. So the solution has to guarantee that once data is start being sent to the printer the above Mbytes/sec speeds are guaranteed until the end of the job (assume that the printer starts printing as soon as the first data is received). Click to Clunk, or total printing time This is the total time between the user clicks to print until the printer has printed the job and returns to the "Ready" status.
