A Business Day at YALMS

• many screen and video streams uploaded by users 15

• many concurrent video annotation tasks (PDF + VIDEO) 16

• constantly changing popularity distribution of content, needs

dynamic relocations

YALMS: The Big SSD Question

.The Question is..

.... can such a rich multimedia architecture benefit fromSSDs?• WHY1: SSDs have properties different from those of HDDs

◦ read/write, random/sequential

• WHY2: SSDs are becoming cheaper (MLC) so why not to use them?

• WHY3: parallel/multicore processing is not kind to HDDs but SSDscan cope

• WHY4: 50Mbytes/s throughput is not enough any more

Where Are We Now? ExistingResearch

.

Existing Research (1)• roughly, two groups:

1. SSD versus HDD research• filesystem abstraction and scheduling -- load balancing between SSD and HDD 01• SSD as cache memory 0203

2. parallel processing and themulticore• job graph partitioning 18• local Big Data processing 19• multicore streaming 11-- 14

Existing Research: What is Missing?

.In a Nutshell, Existing Research is.....

.

• extremely specialized and is built for one application only

• ... or, in business, the use is very primitive -- a temporary memory buffer

• ... at the same time.. YALMS needs generic load balancing◦ one design fits all

• changes along the timeline should cause changes -- dynamic optimization• ...
