Time Slice Size

• David A. presented some thoughts on time slice sizes and made an argument for why larger time slices are better
  • Main advantage is it saves on header words
  • Also reduces the number of time slice boundaries which can be problematic to deal with during analysis

ERSAP Testing

• Vardan reported recent testing
  • Single stream
  • 2.5 GB/s (1CPU @ 100%)
  • JAVA with byte swapping included

Indra lab

• David A. reported Indra machines were booted back up after power outage last week. All seems OK
