Entry  Mon Jul 18 12:00:16 2016, Patrick Coleman-Smith, Report of remote operation of Aida at RIKEN 11/7 to 14/7 

11th July ---------------------------------------------------------------------------------------------------------

09:32 UK time, logged in and power-up all FEEs OK. Setup fine, Temperature Max 12@64

System Checks all fine SYNC count 2243584.

Start Merger and Toggle Pause for no merging.

DAQ start with output enabled.

Toggle Pause in Merger -> “Want First SYNC” with no change.

Tried this several times with the same result.

Checked DAQ statistics => Buffers/sec = 50 to 65, SYNC/sec = 40 to 80  ( should be 384 )

Disabled all ASIC readout and disable all discriminators. DAQ still in GO state.

Fetched new version of ASIC4 with Enable/Disable ASIC readout commands in the “Expert” menu.

SYNC statics now all FEEs are 384/sec.

Merger … Toggle Pause and its fine. 334 items/sec.

DAQ : ASIC4 : Set all slow comparator Thresholds to 250 : Enable ASICs for readout.

Merger now 532811 items/sec.

DAQ SYNC statistics range 307 to 390/sec

LT 22:36 System Checks => Sync counts 6518784 all ok, Sync errors all passed.

LT 23:30 Merger 539826 items/sec. Temperatures => 12@68.12 ; SYNC statistics 361 to 385 ; SYNC counts 8099840 all ok ; Sync errors all ok ; ASIC clock timestamp all ok.

STOP then Power-down all fine.

13th July ----------------------------------------------------------------------------------------------------------------------

Log in and power-up fine.

Backup Merger file ( merge.AD )  and copy latest version from DL. Won’t copy as file already open.

So instead …. Disable ASIC readout, disable Discriminators and run the system.

When Merger is operating , Enable ASIC readout => Merger rate is 8,058,412 items/sec.

LT 19:44 => Temperatures max 12@68.81 , SYNC received 845824 all ok; Sync errors all ok.

LT 20:11 => Merge rate 7,991,198 items/sec, SYNC received 1551359 all ok; Sync errors all ok.

LT 21:07 => Temperatures Max 12@69.00 ; SYNC received 2742272 all.

LT 23:20 => Stopped the whole system.

Kill the Merge process and the Startup process. Copy new Merge.AD successful. Edit Merger startup script to include netint OutputAll 1.

Start up Merger using /MIDAS/Merger/AIDA/Startup in terminal connected to aidas1.

Merger : Setup and configure ; Go ; Toggle Pause All Ok.

Go DAQ   - disable all ASIC readout.

Merger : Toggle Pause ; Merging 8832 items/sec ( = 384 x 23 …. OK )

Connect to TapeServer setup for R3 into /TapeData/July2016 , Go Tape ok.

Merger : Toggle Transfer.

LT 00:08 => enable ASICS for readout. Run for a short while. Merge spinner hesitates for 2 seconds at a time. Merge rate 5,951,471 items/sec. Tape server rate 3,5148 Kbytes/sec.

Stop system, SYNC received 8085504 all ok ; sync error all ok. Power down. Sftp tape data files to nndhcp052 in Daresbury.

14th July -------------------------------------------------------------------------------------------------------------------------

Startup and run the system to tape again R4, ASICs with no discriminators. All fine.

LT 20:19 Enable Discriminators. Merger rate 3.9Mi/sec ( Mega items/second)

LT 20:57 Temperature Max 12@69 , Merge rate 4.2Mi/sec

UK 14:49 Network failure between Daresbury and Edinburgh. Lost contact repeatedly 4 times in a row. Contacted DL network support. No local networking faults.

LT 23:05 Re-connected to Aida in RIKEN. Merger 3.3Mi/sec.

Decided to stop due to concerns about flaky network and leaving the system powered up over the weekend.

SYNC received 7222272 all ok; sync error ok.

Power down. R4_244 is the last file. Written.

The httpd server appears to have died
Entry  Wed Mar 29 05:08:04 2017, TD, Report - medium - delayed or missing authenticated mount requests following FEE64 power cycle messages.log 
This is not, I think, a new observation.

Following FEE64 power cycles we sometimes observe delayed ( ~5-15 minutes ) authenticated mount requests
as the FEE64s mount their root filesystem from the AIDA server aidas1 - see attachment 1. 

There also appears to be an instance of a *missing* authenticated mount request - nnaida10 at 19.51

So this is *a* (but probably not *the*) cause of FEE64 timeouts observed following a FEE64 power cycle
and then waiting 10 minutes before attempting to start the MIDAS DAQ.


I have noticed that these issues appear to be significantly worse when we are using NTFS-mounted USB disks
to backup data from the AIDA server internal disks. Indeed, performance in general is noticeably slower when
using the NTFS-mounted USB disks.

Currently, we attempt to mitigate these issues by either throttling rsync or nice'ing cp.

The analysis of files RIBF127R1/R1_1478 to R1_1486 is appended. This sequence of files should
encompass a correlation reset request (from BRIKEN to AIDA)

There appear to be a number of anomalies

1) MBS correlation scalers observed with one missing 16-bit data value (bits 16-31 or bits 0-15)
   across approximately five files (~20 minutes)

2) The first (presumably) MBS correlation scaler following reset corresponds to a time ~300s (25MHz clock)

I have done a simple test using the system in T9.
Detector on.
Acquisition only ... no Merge
Set pulser attenuation to 2X instead of 10X.

Set Fast Comparator threshold to 50 to be well out of the detector noise.

See attached rate spectrum which shows system operating as I think it should.

Analysing R37_* data files (see https://elog.ph.ed.ac.uk/AIDA/160)

Usinmg MIDASsort, I generate a spectrum showing the time difference (10ns clock cycles)
between sequential ADC data items. There is an offset of 1000.

I observe peaks at 1000, 1200, 1400 etc - as expected

I also observe peaks at +/-10 clock cycles relative to these main peaks - not expected

I also observe some discrete intermediate peaks - not expected

I have investigated this timing using a sort program and R37_0.

If I only work with data from one module there is no problem. Peaks in the time difference spectrum are the
expected 200 apart.

If I then include a second module's ADC data the time difference spectrum starts to look as the one  Tom attached
but with a fixed 45 ticks offset from the '200' peaks.

I conclude the spectra appearance is due to the 500KHz ASIC readout clocks not being synchronized between the
different FEE64 modules.
