RSV Reports for the OSG

by admin posted at 2008-06-11 05:19 last modified 2008-06-11 05:19

Here's a link to the GridView dev server showing the preliminary availability reports for the OSG.  I don't know if the link is permanent or if it will disappear in a few days.

As usual, the plan is to make sure that any interfaces we build match the GridView numbers.

June 9:
  • Continued discussion of CMSSW performance at our site.  Looks finished for awhile.
  • Fixed RAL problem.  Turns out they needed TCP tunings; tunings used were:
    net.ipv4.tcp_window_scaling = 1
    net.ipv4.tcp_timestamps = 0
    net.ipv4.tcp_sack = 0
    net.core.rmem_max = 1048576
    net.core.rmem_default = 87380
    net.core.wmem_max = 131072
    net.core.wmem_default = 32768
    net.ipv4.tcp_rmem = 4096 87380 2097152
    net.ipv4.tcp_wmem = 4096 32768 262144
    net.ipv4.tcp_mem = 65536 87380 196608
    vm.min_free_kbytes = 65536
    vm.overcommit_memory = 2
    Will email these to the T2 list.
