Some quick investigation shows significant speed-up with multiple GPU using TF2, however, as shown in the curve below, the speedup is not linear to the number of GPUs used, there is a balance between GPU # vs speed-up efficiency. The efficiency drops quickly after using 4 GPUs. <html xmlns:v="urn:schemas-microsoft-com:vml" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40";> <head> <meta name=ProgId content=Excel.Sheet> <meta name=Generator content="Microsoft Excel 15"> <link id=Main-File rel=Main-File href="file:///C:/Users/zlao/AppData/Local/Temp/msohtmlclip1/01/clip.htm"> <link rel=File-List href="file:///C:/Users/zlao/AppData/Local/Temp/msohtmlclip1/01/clip_filelist.xml"> <style> <!--table {mso-displayed-decimal-separator:"\."; mso-displayed-thousand-separator:"\,";} @page {margin:.75in .7in .75in .7in; mso-header-margin:.3in; mso-footer-margin:.3in;} tr {mso-height-source:auto;} col {mso-width-source:auto;} br {mso-data-placement:same-cell;} td {padding-top:1px; padding-right:1px; padding-left:1px; mso-ignore:padding; color:black; font-size:11.0pt; font-weight:400; font-style:normal; text-decoration:none; font-family:Calibri, sans-serif; mso-font-charset:0; mso-number-format:General; text-align:general; vertical-align:bottom; border:none; mso-background-source:auto; mso-pattern:auto; mso-protection:locked visible; white-space:nowrap; mso-rotate:0;} .xl65 {text-align:center;} .xl66 {mso-number-format:"\#\,\#\#0"; text-align:center;} --> </style> </head> <body link="#0563C1" vlink="#954F72"> GPU # | batch size | time (seconds) | Speed-up -- | -- | -- | -- 1 | 4,096 | 572 | 1 2 | 8,192 | 300 | 1.90667 3 | 12,288 | 224 | 2.55357 4 | 16,384 | 195 | 2.93333 5 | 20,480 | 176 | 3.25 6 | 24,576 | 168 | 3.40476 7 | 28,672 | 164 | 3.4878 8 | 32,768 | 162 | 3.53086 </body> </html>  -- This is an automated message from the Apache Git Service.
