by an improper cleanup of the worker threads i.e. the cleanup thread is not called early enough. This resulted that the pre-allocated threads no longer are freed and hence the “newthread != NULL” assertion fired. In my case a couple of thread_yield() between
the rounds did the trick, however this is not considered a solution. I haven’t looked at the FT implementation yet but judging from 6 iteration on 64 cores the limit is likely to be reached in iteration 5.

<br>
[@list: sorry for the spam, I'm not sure if Antonio is subscribed and mistakenly replied only to the list...]<br>
<br>
I've investigated a bit and have produced two patches that make the FT benchmark work.<br>
<br>
patch 1 fixes some confusion when creating different cnodes and increases the size of the page cnode by a factor of two. This fixes your immediate problem of not being able to run the FT benchmark. Additionally, changing the page cnode size should now be as
easy as modifying PAGE_CNODE_BITS in include/barrelfish_kpi/init.h.<br>
<br>
patch 2 fixes the FT benchmark itself which was not working because the default stack size on Barrelfish (64kB) is too small for the fft implementation which creates rather large arrays on the stack. This patch is not necessary if you're using a release older
than release2014-08-29.<br>

Hi Antonio,____<br>
<br>
__ __<br>
<br>
Just another thought. I am not sure if the problem at hand is<br>
related to a hard limit on the maximum number of slots in the<br>
SEGCN:____<br>
<br>
__ __<br>
<br>
/* lib/spawndomain/arch/x86/spawn_arch.c */____<br>

261 // XXX: this code assumes that elf_load never needs more<br>
than 32 slots for____<br>
<br>
262 // text frame capabilities.____<br>
<br>
__ __<br>
<br>
The mapping is done with the caps in the SEGCN of the ELF. Can<br>
you verify how many slots you use when loading the ELF?____<br>

I think the CAP error was due to the fact that before<br>
launching the application successfully I mistyped it (after<br>
you launch an application that is not existent is giving the<br>
CAP error problem). I added few printfs in the single slot<br>
allocator code (salloc) and this is the error report right now.<br>

I'm wondering whether this has something to do<br>
with the patch that you<br>
applied... I'm guessing that using BIOS<br>
allocation did not help.<br>
<br>
It might be worth enabling the debug for the<br>
caps system. Can you please<br>
replace the corresponding line in menu.lst with:<br>
<br>
module /x86_64/sbin/cpu loglevel=5 logmask=0x40<br>
<br>
And send us the debug messages?<br>
<br>

<br>
[@list: sorry for the spam, I'm not sure if Antonio is subscribed and mistakenly replied only to the list...]<br>
<br>
I've investigated a bit and have produced two patches that make the FT benchmark work.<br>
<br>
patch 1 fixes some confusion when creating different cnodes and increases the size of the page cnode by a factor of two. This fixes your immediate problem of not being able to run the FT benchmark. Additionally, changing the page cnode size should now be as
easy as modifying PAGE_CNODE_BITS in include/barrelfish_kpi/init.h.<br>
<br>
patch 2 fixes the FT benchmark itself which was not working because the default stack size on Barrelfish (64kB) is too small for the fft implementation which creates rather large arrays on the stack. This patch is not necessary if you're using a release older
than release2014-08-29.<br>

Hi Antonio,____<br>
<br>
__ __<br>
<br>
Just another thought. I am not sure if the problem at hand is<br>
related to a hard limit on the maximum number of slots in the<br>
SEGCN:____<br>

<br>
__ __<br>
<br>
The mapping is done with the caps in the SEGCN of the ELF. Can<br>
you verify how many slots you use when loading the ELF?____<br>

I think the CAP error was due to the fact that before<br>
launching the application successfully I mistyped it (after<br>
you launch an application that is not existent is giving the<br>
CAP error problem). I added few printfs in the single slot<br>
allocator code (salloc) and this is the error report right now.<br>

<br>
Grepping for SYS_ERR_DEPTH_EXCEEDED results in:<br>
kernel/capabilities.c-618- // If lookup<br>
exceeded expected depth then table is malformed<br>
kernel/capabilities.c-619- if (bits_resolved<br>
> vbits) {<br>
kernel/capabilities.c-620-<br>
debug(SUBSYS_CAPS, "caps_lookup_slot: Lookup<br>
exceeded valid bits\n"<br>
kernel/capabilities.c-621- "Cnode<br>
bits = %u, guard size = %u, valid bits = %u\n",<br>
kernel/capabilities.c-622-<br>
cnode_cap->u.cnode.bits,<br>
cnode_cap->u.cnode.guard_size,<br>
kernel/capabilities.c-623- vbits);<br>
kernel/capabilities.c:624: return<br>
SYS_ERR_DEPTH_EXCEEDED;<br>
kernel/capabilities.c-625- }<br>
<br>
I'm wondering whether this has something to do<br>
with the patch that you<br>
applied... I'm guessing that using BIOS<br>
allocation did not help.<br>
<br>
It might be worth enabling the debug for the<br>
caps system. Can you please<br>
replace the corresponding line in menu.lst with:<br>
<br>
module /x86_64/sbin/cpu loglevel=5 logmask=0x40<br>
<br>
And send us the debug messages?<br>
<br>
