Report from Task1

• Simon Casey

Simon: New OS on PC Bogar. Tested libvma on PC Kare, found: 31Gigbit/s with OS stack, limited by receive. With libvma on receive Gigbit/s . But with libvma on transmit, very poor receive throughput. Richard: With libvma on both TX & RX found TX 95 Gigbit/s running at 8972 bytes (MTU9000). receive with no loss only 50-60 Gigbit/s. Found max data payload only 8968 bytes otherwise send 1 frames and kernel had to re-assemble. Jimmy: JBO 2 PCs built for DTN nodes, dual Xeon with ConnectX-4; OS sci Linux 7.3 (kernel 3.1). Kernel old so could go to later RH or Centos or Fedora. Action: select and install Staring setup of 10Gigabit tests across Europe. Created wiki page for test nodes Action: all to complete the information on the wiki for their nodes. Created wiki pages for data transfer programs Action: send round ssh keys and network originating the ssh call for ACL setup. Update on 100GE to JBO: MoU with JISC(JANET) progressing with draft. Building work at JBO for SKAO new offices so expect diverse BT network link on 3 months - Sep 17?
