This page will document the data transfers from/to PDSF to/from BNL in the summer/autumn of 2009.

I repeated earlier tests I had run with Dan Gunter (see below "Previous results"). It takes onlt 3 streams to saturate the 1GigE network interface of stargrid04.

After replacing network card to 10GigE so that we could plug directly into the core switch quicktest gives:

More work tomorrow.
October 15, 2009
Comparison between the signal from an optical tap at the NERSC border with the tcpdump on the node showed most of the loss happening between the border and pdsfsrm.nersc.gov.
More work was done to optimize single-stream throughput.
Changes resulted in an improved throughput but it is stillfar from what should be (see details below). We are going to insert a 10 GigE card into the node and move it even closer to the border.
Here are the results with those buffer memory settings as of the morning 10/15/2009. There is a header from the first -------------------------------------------------------------------------
measurement and then results from a few tests run minutes apart.

Then I restored the "dtn" buffer memory settings - again morning 10/15/2009 and I got similar if not worse results:

Since the "80Mb/s or worse" persisted for a long time and was measured on various occasions the new numbers are due to the forceth param or the switch change. Most probably it was the switch. It is also true that the "dtn" settings were able to cope slightly better with the location on the Dell switch but seem to be not doing much when pdsfgrid2 is plugged directly into the "old pdsfcore" switch.

Notes on third party srm-copy to PDSF:
1) on PDSF interactive node, you need to set up your environment:
source /usr/local/pkg/OSG-1.2/setup.csh
2) srm-copy (recursive) has the following form:
srm-copy gsiftp://stargrid04.rcf.bnl.gov//star/institutions/lbl_prod/andrewar/transfer/reco/production_dAu/ReversedFullField/P08ie/2008/023b/ srm://pdsfsrm.nersc.gov:62443/srm/v2/server\?SFN=/eliza9/starprod/reco/production_dAu/ReversedFullField/P08ie/2008/023/ -recursive -td /eliza9/starprod/reco/production_dAu/ReversedFullField/P08ie/2008/023/
October 1, 2009
We conducted srm-copy tests between RCF and PDSF this week. Initially, the rates we saw for a third party srm-copy between RCF (stargrid04) and PDSF (pdsfsrm) are detailed in plots from Dan:
September 24, 2009
We updated the transfer proceedure to make use of the OSG automated monitoring tools. Perviously, the transfers ran between stargrid04 and one of the NERSC data transfer nodes. To take advantage of Dan's automated log harvesting, we're switiching the target to pdsfsrm.nersc.gov.
Transfers between stargrid04 and pdsfsrm are fairly stable at ~20MBytes/sec (as reported by the "-vb" option in the globus-url-copy). The command used is of the form:
globus-url-copy -r -p 15 gsiftp://stargrid04.rcf.bnl.gov/[dir]/ gisftp://pdsfsrm.nersc.gov/[target dir]/
Plots from the first set using the pdsfsrm node:
The most recent rates seen are given in Dan's plots from Sept. 23rd:
So, the data transfer is progressing at ~100-200 Mb/s. We will next compare to rates using the new BeStMan installation at PDSF.
Tests have been repeated as a new node (stargrid10) became available. We ran from the SRM end host at PDSF pdsfgrid2.nersc.gov to the new stargrid10.rhic.bnl.gov endpoint at BNL . Because of firewalls we could only run from PDSF to BNL, not the other way. A 60-second test got about 75Mb/s. This number is consistent with earlier iperf tests between stargrid02 and pdsfgrid2.
globus-url-copy with 8 streams would go up 400Mb/s and 16 streams 550MB/s. Also with stargrid10, the transfer rates would be the same to and from BNL.
Details below.

Baseline from bwctl from SRM end host at PDSF -- pdsfgrid2.nersc.gov -- to a perfsonar endpoint at BNL -- lhcmon.bnl.gov. Because of firewalls, could only run from PDSF to BNL, not the other way around. Last I checked, this direction was getting about 5Mb/s from SRM. A 60-second test to the perfsonar host got about 275Mb/s.
Summary: Current baseline from perfSONAR is more than 50X what we're seeing.

Measured between the STAR SRM hosts at NERSC/PDSF and Brookhaven:
Current data flow is from PDSF to BNL, but plans are to have data flow both ways.
All numbers are in megabits per second (Mb/s). Layer 4 (transport) protocol was TCP. Tests were at least 60 sec. long, 120 sec. for the higher numbers (to give it time to ramp up). All numbers are approximate, of course.
Both sides had recent Linux kernels with auto-tuning. The max buffer sizes were at Brian Tierney's recommended sizes.
Tool: iperf
Tool: globus-url-copy (see PDSF to BNL for details). This was to confirm that globus-url-copy and iperf were roughly equivalent.
Tool: globus-url-copy (gridftp) -- iperf could not connect, which we proved was due to BNL restrictions by temporarily disabling IPtables at PDSF. To avoid any possible I/O effects, ran globus-url-copy from /dev/zero to /dev/null.
Below are results from iperf tests bnl to lbl. 650 Mbps with very little loss is quite good. For the uninformed (like me), we ran iperf server on dlolson.lbl.gov listening on port 40050, then ran client on stargrid02.rcf.bnl.gov sending udp packets with max rate of 1000 Mbps [olson@dlolson star]$ iperf -s -p 40050 -t 60 -i 1 -u [ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams [ 3] 40.0-41.0 sec 78.3 MBytes 657 Mbits/sec 0.012 ms 0/55826 (0%) [ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams [ 3] 41.0-42.0 sec 78.4 MBytes 658 Mbits/sec 0.020 ms 0/55946 (0%) [ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams [ 3] 42.0-43.0 sec 78.4 MBytes 658 Mbits/sec 0.020 ms 0/55911 (0%) [ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams [ 3] 43.0-44.0 sec 76.8 MBytes 644 Mbits/sec 0.023 ms 0/54779 (0%) [ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams [ 3] 44.0-45.0 sec 78.4 MBytes 657 Mbits/sec 0.016 ms 7/55912 (0.013%) [ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams [ 3] 45.0-46.0 sec 78.4 MBytes 658 Mbits/sec 0.016 ms 0/55924 (0%) [ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams [ 3] 46.0-47.0 sec 78.3 MBytes 656 Mbits/sec 0.024 ms 0/55820 (0%) [ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams [ 3] 47.0-48.0 sec 78.3 MBytes 657 Mbits/sec 0.016 ms 0/55870 (0%) [stargrid02] ~/> iperf -c dlolson.lbl.gov -t 60 -i 1 -p 40050 -u -b 1000M [ ID] Interval Transfer Bandwidth [ 3] 40.0-41.0 sec 78.3 MBytes 657 Mbits/sec [ ID] Interval Transfer Bandwidth [ 3] 41.0-42.0 sec 78.4 MBytes 658 Mbits/sec [ ID] Interval Transfer Bandwidth [ 3] 42.0-43.0 sec 78.4 MBytes 657 Mbits/sec [ ID] Interval Transfer Bandwidth [ 3] 43.0-44.0 sec 76.8 MBytes 644 Mbits/sec [ ID] Interval Transfer Bandwidth [ 3] 44.0-45.0 sec 78.4 MBytes 657 Mbits/sec [ ID] Interval Transfer Bandwidth [ 3] 45.0-46.0 sec 78.4 MBytes 658 Mbits/sec [ ID] Interval Transfer Bandwidth [ 3] 46.0-47.0 sec 78.2 MBytes 656 Mbits/sec [ ID] Interval Transfer Bandwidth [ 3] 47.0-48.0 sec 78.3 MBytes 657 Mbits/sec Additional notes: iperf server at bnl would not answer tho we used port 29000 with GLOBUS_TCP_PORT_RANGE=20000,30000 iperf server at pdsf (pc2608) would not answer either.
