Again, thank you for your responses.
So please let me clarify a few points to be sure.
1. 'hergp' is saying that if the issue is that they are using a T1 T2 type multi core SPARC than the issue is not so much the 32 vs 64 bit compile as it is the single threaded vs multi-threaded processing. Correct?
On Windows x86 vs X64 we found that the increase in compiling to X64 is just under 20% (comparing the running of one process on the same input data). Would you expect something similar on SPARC?
2. 'jlliagreis' saying that if it is possible to design our program to be multi-threaded (which I don't think we can) or if we run the program in parallel processes on different sets of data instead of in sequence, then we should be able to see some improvement. However, the amount will depend on the type of bottle neck we are experiencing (which we do not know yet). So for example, if it is straight CPU bound then we should see the best improvement, whereas if it is I/O bound then they may be less improvement, etc.
3. How do I know if we are running T1 or T2 with regard to floating point? I noticed that you said it is niagara based on the sun4v. How do I tell what T level they have?
4. What Solaris SPARC hardware would be better for doing this type of processing? I am not sure we have a choice but I am certainly curious.

One other things. They have two servers. One is a T2 and the other a T3 and specifically they are:SunOS 5.10 Generic_147440-09 sun4u sparc SUNW,Sun-Fire-V245 (T2)
SunOS 5.10 Generic_147440-01 sun4v sparc sun4v (T3)
What does this tell us about single thread / multi-thread or floating point etc?
How does sun4v differ from sun4u? How does T2 differ from T3?
Thank you.

I know that Sun make s a version of Solaris for Sparc platforms and also an x86 (Intel/AMD) release of Solaris. Can an application that runs on Solaris/Sparc also run on a PC running the x86 release of Solaris? Would a different release be required or any re-compling of the application?

Hi,
We are porting our application from 32bit to 64bit.
We tried -xarch=v9, -xarc=v9a and -xport64=full options so that compiler to issue 64bit porting warnings.
But we are not getting any porting warninings
WE are using CC 5.5 compiler on sparc-solaris m/c.

NAME
n2cp - Ultra-SPARC T2 crypto provider device driver
DESCRIPTION
The n2cp device driver is a multi-threaded, loadable hardware driver supporting hardware-assisted acceleration of the following crypto-
graphic operations, which are built into the Ultra-SPARC T2 CMT processor:
DES: CKM_DES_CBC, CKM_DES_ECB
DES3: CKM_DES3_CBC, CKM_DES3_ECB,
AES: CKM_AES_CBC, CKM_AES_ECB, CKM_AES_CTR, CKM_AES_CCM, CKM_AES_GCM
RC4: CKM_RC4
MD5: KM_MD5, CKM_MD5_HMAC, CKM_MD5_HMAC_GENERAL,
CKM_SSL3_MD5_MAC
SHA-1: CKM_SHA_1, CKM_SHA_1_HMAC,
CKM_SHA_1_HMAC_GENERAL, CKM_SSL3_SHA1_MAC
SHA-256:CKM_SHA256, CKM_SHA256_HMAC,
CKM_SHA256_HMAC_GENERAL
CONFIGURATION
You configure the n2cp driver by defining properties in the /kernel/drv/n2cp.conf which override the default settings. The following prop-
erty is supported:
nostats Disables the generation of statistics. The nostats property may be used to help prevent traffic analysis, how-
ever, this may inhibit support personnel.
CRYPTO STATISTICS
Solaris crypto drivers must implement statistics variables. The n2cp driver maintains the following statistics:
cwqXstate State (online, offline, error) of respective cryptographic engine, CWQ X.
cwqXsubmit Number of jobs submitted to CWQ X.
cwqXqfull Number of times when submitting a job that the queue for CWQ X was full.
cwqXqupdate_failure Number of submit job failures on CWQ X.
des Total number of jobs submitted to device for DES operations.
des3 Total number of jobs submitted to device for DES3 operations.
aes Total number of jobs submitted to device for AES operations.
md5 Total number of jobs submitted to device for MD5 operations.
sha1 Total number of jobs submitted to device for SHA-1 operations.
sha256 Total number of jobs submitted to device for SHA-256 operations.
md5hmac Total number of jobs submitted to device for HMAC_MD5 operations.
sha1hmac Total number of jobs submitted to device for HMAC_SHA-1 operations.
sha256hmac Total number of jobs submitted to device for HMAC_SHA-256 operations.
ssl3md5mac Total number of jobs submitted to device for SSL3_MAC_MD5 operations.
ssl3sha1mac Total number of jobs submitted to device for SSL3_MAC_SHA-1 operations.
ssl3sha256mac Total number of jobs submitted to device for SSL3_MAC_SHA-256 operations.
Note -
Additional statistics targeted for Sun support personnel are not documented in this manpage.
