9/24/2002 4:01 PM. No FECs, no disks. Integrating FPDP

 

Made a loopback mode in the Collector. This is defined by LOOPBACK.

The Mercury works stable. 

If the output rate is higher than 32 MB/s (330 Hz)  then messages appears:

[0]MasterMode3(): Event Builder queue is almost full, 7046f,7046e,0

If the output rate is close to 33 MB/s then system is saturated.

At this rate the Suspend on RINT0 is shining dimly.

 

There was difficult to debug phatdaq with fpdp. I disabled the fpdp support in slimdaqc and started separate program test_fpdplib which reads the fpdp interface. When I started first time it was only one complain in the collector that dqout was busy for more than 10 ms but after that it works fine at 30 MB/s or 300 Hz. The CPU on usp was 76% user busy. When I CtrlC on phatdaq the CPU dropped to 1% us, 25% sy, 76 % id.

Suspend on FPDP glimmers at ~ 5Hz. Suspend on RINT0

 

Prototype DAQ works at 300 Hz!

 

Prototype = Disks and FASTBUS are not connected, broken slimdaq.

 

No errors in FECs, that sounds suspicious.

 

Applied rate 10kHz, Accepted rate 300 Hz, 30 MB/s
 

 

 

9/25/2002 9:17 AM

Left system running since ~19:00,  usp crashed @ 23:32 after 7.5 MEv.

Sep 24 23:32:38 usp fpdp: fpdp_ioctl maximum transfer size exceeded

9/25/2002 4:11 PM. Running slimdaq with FPDP support.

It works for several minutes and then goes high wired

Todo: debug the system for proper throttling. I.E stop slimdaq, the ROC should react nicely.

By the way performance is similar to yesterday’s.

 

9/26/2002 8::00 PM. Debugging pipelining.

The blocking still not working properly. If slimdaq is paused then collector slows down due to suspended output, output queue in mercury overflows, master sets back pressure and don’t acknowledge, watchdog in EMM complains that Si is not responding and initiates start/stops.

 

Running with writing

The maximum sustained rate is 20 MB/s, still have 40% idle CPU time. The writer queue in average is empty but spontaneously gets overflowed.

Talked to Piotr about L1 and L2. He does not know how the L2 acceptance window is organized in FEC. He suggest to apply shortened L1 not apply L2 and measure BusyL2.

 

Fig. S2091313. Only DAQ Busy applied to the system. The system is unstable at 400+ Hz

 

Fig. S209271502. All busy’s are applied too the system. The system is stable as Swiss watch.

 

FECs on, disk off

System can accept 340 Hz sustained, after that the FPDP begin suspending the system, the event fifo is empty. It can accept bursts at 500 Hz bursts during ~1 sec.

At 340 Hz CPU usage is 25% sy, 2% us, and 75% id!.

 

No FEC errors.

At 1/(2.66 ms) the output queue becomes full and accepted rate drops to 280 Hz

 

At higher rate FEC errors:

Pauses

After applying all busy (L1, L2, MDC) the system works as a Swiss watch. Applied 500 Hz received 300 Hz. On the picture 1432 I see random pauses in data taking which lasts for ~ 20 ms (Solaris ticks?).

Note of 10/03/02. The 20 ms pause was in the code. After removing it the receiving rate increased only slightly – to 330 Hz.

Writing to disk with real data processing

27 MB/s, 100 Hz, event size 0x47000 = 290kB

 

Summary:

Today we ran the new DAQ with FECs under following conditions:

Only Silicon hardware have been tested.

The disk interface was not optimal. Due to a missing SCSI cable it runs only at 40 MB/s (this cable should be delivered soon).
