The phrase "a speedup of a factor" is correct and usable in written English.
It can be used when discussing improvements in performance, efficiency, or processing time, often in technical or scientific contexts.
Example: "The new algorithm achieved a speedup of a factor of three compared to the previous version."
Alternatives: "an improvement by a factor" or "a performance increase of a factor".
Furthermore, a speedup of a factor of at least two was observed over a standard space-marching algorithm using a limited scheme for optically thick scattering media.
For a two-dimensional system with 200 components and 100 points on each boundary, we gain a speedup of a factor of 100 from the new analytic formulation and a factor of 50 from the fast multipole method.
Since genetic algorithms are inherently parallel, the GPGPU computing paradigm leads to a speedup of a factor of 200× in the training phase with respect to the CPU based version.
When using 59 tasks (15 nodes), we observe a speedup of a factor 18.11 compared with using 3 tasks (1 node).
When using 64 tasks (16 nodes), a speedup of a factor 14.16 is achieved compared with using 4 tasks (1 node) (see Fig. 3).
On the largest problem, a parallel speedup of a factor of four is observed when using eight processors.
In this paper, we present a semi-analytical integration scheme that offers a total speedup of a factor 30 compared to the Verlet method on typical MD simulation by allowing over three orders of magnitude larger step sizes.
The speedup of a factor between 10 and 11 is realized.
This algorithm converts the latency bounded computations to throughput oriented ones, and maximizes the utilization of the pipelined hardware that underlies the instruction, achieving speedup of a factor of almost 3.
We achieved speedup of a factor of 120 while preserving accuracy and reliability of the results.
Indeed, whereas Halvade requires ∼48 h on a single node, ∼120 h are required when Halvade is not applied (speedup of a factor 2.5).
