Qtc

Quality Threshold Clustering (QTC)

Description: Measures performance of the Quality Threshold Clustering algorithm.

Problem Sizes (number of points, threshold)

• s=1 ( 8*1024, 1)
• s=2 (16*1024, 1)
• s=3 (16*1024, 4)
• s=4 (26*1024, 1)

With these sizes, a run on a Tesla C2070, will take approximately: 3.5, 16, 90 and 550 seconds respectively

Precision: float

Includes PCIe Transfer Time: Yes, in [testName]_PCIe measurements

Parameters

• --s, preselected problem sizes (overrides all other parameters)
• --PointCount, point count
• --DataFile, BLAST data input file name
• --Threshold, cluster diameter threshold
• --SaveOutput, save the resulting clusters in different files
• --Verbose, print cluster cardinalities
• --TextureMem, use Texture memory for distance matrix
• --Dense, use the compact storage distance matrix regardless of problem size

Specific Tests
